Four More Bullsh*t Marijuana Myths Busted Using the Fed’s Own Numbers

marijuana, facts, NORML, prohibition, states, report,

My apologies for getting this little nugget out to you guys late but you know how it is when you’re trying to pay attention and…well, you know how it is. Nevertheless, guess what I’ve got!?!

The Federal government’s annual report highlighting substance abuse. Now that may not sound interesting when I put it like that but if you look through the 300+ pages like Paul Armentano of NORML did right here. You’ll find even more myth busting information by comparing the data but in the meantime, here’s the breakdown.

Four More Bullsh*t  Mary Jane Myths BUSTED!!!

  • Myth: Marijuana use is prevalent in low income and urban areas thereby justifying the “War on Drug” and aggressive treatment and surveillance of poorer (read: Black and Latino) neighborhoods.

…..combating numerous drug warrior myths and stereotypes (such as the notion that high rates of illicit drug use — yes, the New England states lead in this broader category too — are typically relegated to poorer, urban, more racially diverse areas).

  • Myth: Marijuana use is neither determined nor undermined by state drug laws. People use marijuana if and when they choose to and not because states make marijuana possession laws harder.

…..it should be noted that despite the prevalence of medical marijuana states in these rankings, the authors of the report acknowledge that there is no evidence that the implementation of medi-pot laws is increasing the use of cannabis or other illicit drugs.

  • Myth: Establishing medical marijuana laws do not directly affect an increase in casual marijuana use.

They also call into question the notion that marijuana use among the general population is in any way influenced by the legal status of marijuana.

  • Myth: The Northeast loves them some Mary Jane. Nearly every state in the region made it’s way into the top spots for marijuana use.

The totals in the category ‘marijuana use in the past year among persons age 18 to 25‘ is even more New England-centric, with every northeast state (Connecticut, Massachusetts, Maine, New Hampshire, Rhode Island, and Vermont) all included in the top percentile (along with Alaska, Colorado, New York, and Oregon). In the category, ‘marijuana use in the past month among persons age 26 or older‘ Massachusetts, Maine, New Hampshire, Rhode Island, and Vermont top the list (along with Alaska, Colorado, Hawaii, and Oregon).

So, according this report by the United States government marijuana use is not the big bad monster that they make it out to be. With social concerns and morals aside, I wonder if a level-headed person would read this and ask themselves what the implication of this data means.

At the very least, our government has inflated the seriousness of marijuana’s affects on society. The decision to do so may have caused a  focus of limited state resources on treating a problem that may not have been a priority compared to other social issues.

At the very worst, this data shows a how an entire class of people (poor/brown) have been manufactured into a criminal class justifying the pursuit, expense and time required by the state to prosecute them when their marijuana use maybe less prevalent than in other (upper-class/white) areas. So if the real intent of the state is to pursue those that use illicit drugs the their polices effort to lock up offenders would correlate with drug use. This one theory begs the question of the states willingness to exploit their own criminal justice system to violate the rights of citizens to fund private industries that benefit from such discretion, specifically, the courts, the prisons and the legal industry.

Don’t be intimidated by false marijuana myths, educate yourself and stop the stupid with real data made by the same people that we’re fighting. Shout out to Norml for doing the hard part, now all you have to do is repeat it. Almost like cheating on a test but not. Until next time, people

Marijuana Growers’ Kids In Better Health According To Canadian Study

Canada grow roomBy Steve Elliott of Toke of the Town

A new study from Canada flies in the face of stereotypes regarding the offspring of marijuana-growing parents. Children from homes where cannabis is grown were healthy and drug-free, according to the study — in fact, healthier than other children — leading to questions about why such kids are often removed from their homes.

The research from the Motherisk Program at Toronto’s Hospital for Sick Children indicates the automatic removal of kids from marijuana-growing parents can be worse for the children than allowing them to stay at home, according to Gideon Koren, a University of Toronto professor and the program’s director, reports CBC News.

“After examining 75 of the kids over several years, we came to very clear conclusions that a vast majority of these kids are doing well,” Koren said. “Well fed, well kept, doing well in school and developing well.”

“In fact, the health problems found in this population were actually fewer than those in the general Canadian population,” according to a news release from the Hospital for Sick Children.

Children often enjoyed the lifestyle benefits of having high-income parents — even though that income is made illegally — and taking them away often “does a lot of damage,” Koren said.

“Taking a small child from his or her parents in a well-adapted environment causes fear, anxiety, confusion and sadness — everything that comes from separation,” he said.

When children are found in homes identified as marijuana-growing operations, they are usually removed, separating them from their parents and often placing them into foster care.

The Hospital for Sick Children examined 75 kids between 2006 and 2010 from Ontario’s York Region, just north of Toronto.

canada marijuanaSince 2006, child-welfare workers have learned more about the effects marijuana grow-ops have on children and have changed how they maintain the children’s safety, according to Patrick Lake, executive director of the York Region Children’s Aid Society.

“We have developed a more customize and comprehensive process to determine best response, on a case-by-case basis, while looking for ways to safely maintain children with their parents or relatives,” Lake said.

This was the first study done on the topic, and the findings mean authorities will now see these children differently, according to Koren.

“When police and children’s aid go into that situation, they have to look much more carefully on what happened to that child, and now blanket-wise moving kids out of their homes,” he said.

Upside Down Reasoning in Australia

Because they're in the southern hemisphere, you see.

Researchers based out of James Cook University in Queensland, Australia have been doing some research into cannabis use among the Aboriginal population in the far northern, tropical area of Cape York. The researchers reported their findings at the Tropical Medical Conference in Cairnes last weekend. The researchers stated, presumably with straight faces, that marijuana was causing a 50% rate of mental illness in the Aborigine community. This is like hitting someone with an axe and determining death was caused by their resultant fall to the ground.

The study, if one can call it that, is part of the Cape York Cannabis Project: “a part of the Weed it out initiative run by the Queensland Police Service and James Cook University, the aim of which is to promote Indigenous community action to reduce harms associated with heavy cannabis use in remote communities in the Cape York region.”

The basis of the scientific method is basically: 1. coming up with an idea, 2. testing that idea using experiments and observations and 3. comparing those results to your original idea in order to see if it is valid. On the other hand, there is propaganda: coming up with an idea and then selectively pulling or inventing information that backs your idea in order to make it believable. Which of these two do you think applies to a “study” funded by an anti-cannabis police initiative? The outcome and findings were never in question, thus the findings aren’t scientifically valid. The fact that the spurious results are even getting media attention does a disservice to humanity.

JCU Assoc. Prof. Alan Clough headed the “research” team along with associate Dr. India Bohanna. They determined that, since 50% of the population surveyed reported using marijuana, and 50% of the individuals were reported to have at least one symptom of mental illness, pot was causing the illness.

OH REALLY? So, let’s see: the Australian aborigines, the original inhabitants of the Australian continent, have (since the British colonized Oz in 1788) had their homeland effectively stolen, their culture brutally discouraged, been massacred, and had their children stolen from them, and have a life expectancy 17 years shorter than the average white Aussie, have a high incidence of mental illness because they use cannabis?

Mr. Clough and Ms. Bohanna were both paid to come up with that exact result, and I hope they were paid well to mortgage their professional reputations, because no one can take anything they publish seriously ever again after that preposterous claim.

Medical Marijuana Research Conference To Be Held in Illinois

International Medical Marijuana Research Conference Held This Week Near Chicago
White House sponsors conference only days after it threatens medical marijuana states

Chicago, IL — Starting tomorrow, the International Cannabinoid Research Society (ICRS) will hold its 21st annual symposium in St. Charles, Illinois, just outside of Chicago . Notably, this year’s symposium is sponsored in part by an array of pharmaceutical companies, the U.S. National Institute on Drug Abuse (NIDA), and ElSohly Laboratories, Inc., the federal government’s only licensed source of research-grade cannabis (marijuana) used in therapeutic studies. The symposium features poster presentations by four members of the Multidisciplinary Scientific Advisory Board of Americans for Safe Access — Dr. William Courtney, Dr. Jeff Hergenrather, Jahan Marcu and Dr. Amanda Reiman.

This important public health symposium is taking place less than a week after Deputy Attorney General James Cole inconspicuously issued a memorandum on June 29th to U.S Attorneys, defending the government’s threats of criminal prosecution against local and state officials, as well as others producing or distributing medical marijuana even if such actions are legal under state law. Rarely has the federal government threatened public officials over the development and passage of their own public health laws.

“This symposium and its sponsors shows that medical cannabis is a valid medication that has been recognized and studied by scientists right under our noses,” said Steph Sherer, Executive Director of Americans for Safe Access (ASA), the country’s leading medical marijuana advocacy group. “meanwhile, the federal government continues its antiquated, political campaign to undermine the ability of millions of patients to safely and legally obtain their medication.”

Part of what’s happening this week includes a presentation by Temple University doctoral student, ASA Advisory Board member, and cannabinoid researcher Jahan Marcu, focusing on research around cannabinoid receptors in the brain to better understand how and which parts of the cannabis plant work best with the human body. Marcu previously published findings in the Journal of Molecular Cancer Therapeutics on a study showing enhanced anti-cancer effects with certain compounds found in the cannabis plant. For his presentation in 2009, Marcu received the prestigious “Billy Martin Award” from the ICRS.

Dr. Amanda Reiman will be presenting on dispensary-based research and models for patient access to whole-plant medicine. While an ASA Advisory Board member, Reiman was also a postdoctoral fellow in the School of Public Health at the University of California, Berkeley, and is currently a medical cannabis researcher who regularly presents at ICRS and other related conferences. Reiman’s research on the impact of localized medical marijuana distribution on patients is particularly relevant given the federal effort to undermine the regulation of such facilities.

“The federal government cannot both support medical marijuana and undermine its legal implementation,” continued Sherer. “This contradictory policy must end.” The government has multiple options currently available, not the least of which is a 9-year-old petition to reclassify marijuana now pending before the Drug Enforcement Administration, as well as Congressional legislation recently introduced by Rep. Barney Frank (D-MA), HR 1983, which also calls for rescheduling marijuana from its position as a dangerous drug with no medical value.

Study Claims Marijuana Users Don’t Care If They Lose Money

Graphic: NowPublic
Yikes! We can’t have people caring less about MONEY! This is a capitalistic society, after all!
​ Smoking marijuana makes you care less about money, at least if you believe the conclusions of a recent “scientific” study from an obviously anti-pot bunch of capitalistic Bible-thumpers at Wake Forest Baptist Medical Center.
“Smoking marijuana affects peoples’ impulsivity, attention, memory, cognition and decision-making abilities,” the authors of the study claim in a June 21 news release. “That’s been scientifically proven.” Well, yeah, man, at least if the stuff’s any good.

The researchers claim their findings are “important because they demonstrate a potential, negative side effect of chronic marijuana use.” Hell, in this economy, caring less about money seems like a survival trait, to me.

“Understanding how marijuana influences the perception of what is ‘negative’ may help explain continued marijuana use and aid in the development of effective strategies for treatment therapies,” said lead author Michael J. Wesley, Ph.D., department of Physiology and Pharmacology at Wake Forest Baptist. (Translation: You’re bad, we’re Baptists, and we’re here to help you.)
“Published data suggests that marijuana use is increasing, both recreationally and medically,” said Captain Obvious, I mean Dr. Wesley. “However, the misperception that it’s harmless is also rising. It’s imperative that we begin analyzing the effects of long term, heavy marijuana use.”
Published by Psychiatry Research in the January 2011 issue, Wesley’s study was supported by grants from the — surprise, surprise! — National Institute on Drug Abuse (NIDA), which won’t fund studies unless they are specifically constructed to search for something, anything negative about pot.
Wesley and his fellow researchers on the study are this week attending the annual meeting of the College on Problems of Drug Dependence (that convention certainly sounds like a happening party, doesn’t it?) in Florida. Wesley presented preliminary findings from the study last year at the conference.
NIDA claimed last December that regular marijuana use is on the rise among teenagers, citing an increase of more than 10 percent in students in 8th, 10th, and 12th grades.
In the study, researchers said that marijuana users “performed poorly” on the Iowa Gambling Task (IGT), which is a complex decision-making task in which participants make choices under ambiguous conditions and win or lose money based on their choices.
The goal of the IGT is to use the feedback of the wins and losses to guide future choices toward supposed “safe options” that result in winning more and losing less.
Sixteen “chronic marijuana users” and 16 controls, or non-users, performed a modified IGT in a magnetic resonance imaging (MRI) scanner. Performance was tracked and functional brain activity in response to early wins and losses was examined.
Researchers were looking to see if the perceived “poor performance” of marijuana users was related to differences in brain activity while evaluating the positive and negative information conveyed by wins and losses during the early, strategy development phase of the IGT.
For the control group, after multiple exposures to early large monetary losses, they began to choose “safer,” less negative options on the task. In contrast, the damn potheads, I mean the marijuana users generally failed to alter their selection patterns and continued to make what the researchers deemed “disadvantageous choices” throughout the task.
The researchers said that this was because the marijuana users were “less sensitive to the negative feedback” during strategy development. I call bullshit; the pot smokers obviously just weren’t taking the money game as seriously as the stressed-out straights.
“The marijuana users appear to have a blunted response to losing,” Wesley said uncomprehendingly. “They don’t figure out a strategy to avoid monetary losses and this is associated with a decreased functional brain response to the early, negative information that guides the other group to safer choices.
“The bottom line is that it looks like they don’t care as much if they lose,” Wesley said.
Larger Study Showed No Impact On Decision Making
The results of the study contradict clinical trial data from a large study in 2007 which indicate that marijuana intoxication does not adversely affect decision making. In that study, published in the Journal of Clinical and Experimental Neuropsychology, investigators at New York State’s Psychiatric Institute and Columbia University looked at the impact of acute cannabis intoxication on the decision-making abilities of 36 subjects, as assessed by, you guessed it, the Iowa Gambling Task.
Volunteers in that study completed the IGT once sober and three times after smoking cannabis or a placebo. Though using cannabis increased the time required for subjects to complete their tasks, volunteers’ accuracy was not adversely affected by pot.
“Advantageous card selection and money earned on the task were not disrupted by marijuana,” the authors concluded. “These data are consistent with previous findings that indicated that speed of performance on tests of executive function, but not accuracy, is disrupted in experienced marijuana users during marijuana intoxication.”

Top 10 Cannabis Studies The Government Wishes It Didn’t Fund

10) MARIJUANA USE HAS NO EFFECT ON MORTALITY:
A massive study of California HMO members funded by the National Institute on Drug Abuse (NIDA) found marijuana use caused no significant increase in mortality. Tobacco use was associated with increased risk of death. Sidney, S et al. Marijuana Use and Mortality. American Journal of Public Health. Vol. 87 No. 4, April 1997. p. 585-590. Sept. 2002.
9) HEAVY MARIJUANA USE AS A YOUNG ADULT WON’T RUIN YOUR LIFE:
Veterans Affairs scientists looked at whether heavy marijuana use as a young adult caused long-term problems later, studying identical twins in which one twin had been a heavy marijuana user for a year or longer but had stopped at least one month before the study, while the second twin had used marijuana no more than five times ever. Marijuana use had no significant impact on physical or mental health care utilization, health-related quality of life, or current socio-demographic characteristics. Eisen SE et al. Does Marijuana Use Have Residual Adverse Effects on Self-Reported Health Measures, Socio-Demographics or Quality of Life? A Monozygotic Co-Twin Control Study in Men. Addiction. Vol. 97 No. 9. p.1083-1086. Sept. 1997
8) THE “GATEWAY EFFECT” MAY BE A MIRAGE:
Marijuana is often called a “gateway drug” by supporters of prohibition, who point to statistical “associations” indicating that persons who use marijuana are more likely to eventually try hard drugs than those who never use marijuana – implying that marijuana use somehow causes hard drug use. But a model developed by RAND Corp. researcher Andrew Morral demonstrates that these associations can be explained “without requiring a gateway effect.” More likely, this federally funded study suggests, some people simply have an underlying propensity to try drugs, and start with what’s most readily available. Morral AR, McCaffrey D and Paddock S. Reassessing the Marijuana Gateway Effect. Addiction. December 2002. p. 1493-1504.

7) PROHIBITION DOESN’T WORK (PART I):
The White House had the National Research Council examine the data being gathered about drug use and the effects of U.S. drug policies. NRC concluded, “the nation possesses little information about the effectiveness of current drug policy, especially of drug law enforcement.” And what data exist show “little apparent relationship between severity of sanctions prescribed for drug use and prevalence or frequency of use.” In other words, there is no proof that prohibition – the cornerstone of U.S. drug policy for a century – reduces drug use. National Research Council. Informing America’s Policy on Illegal Drugs: What We Don’t Know Keeps Hurting Us. National Academy Press, 2001. p. 193.

6) PROHIBITION DOESN’T WORK (PART II):
(DOES PROHIBITION CAUSE THE “GATEWAY EFFECT”?): U.S. and Dutch researchers, supported in part by NIDA, compared marijuana users in San Francisco, where non-medical use remains illegal, to Amsterdam, where adults may possess and purchase small amounts of marijuana from regulated businesses. Looking at such parameters as frequency and quantity of use and age at onset of use, they found no differences except one: Lifetime use of hard drugs was significantly lower in Amsterdam, with its “tolerant” marijuana policies. For example, lifetime crack cocaine use was 4.5 times higher in San Francisco than Amsterdam. Reinarman, C, Cohen, PDA, and Kaal, HL. The Limited Relevance of Drug Policy: Cannabis in Amsterdam and San Francisco. American Journal of Public Health. Vol. 94, No. 5. May 2004. p. 836-842.

5) OOPS, MARIJUANA MAY PREVENT CANCER (PART I):
Federal researchers implanted several types of cancer, including leukemia and lung cancers, in mice, then treated them with cannabinoids (unique, active components found in marijuana). THC and other cannabinoids shrank tumors and increased the mice’s lifespans. Munson, AE et al. Antineoplastic Activity of Cannabinoids. Journal of the National Cancer Institute. Sept. 1975. p. 597-602.

4) OOPS, MARIJUANA MAY PREVENT CANCER, (PART II):
In a 1994 study the government tried to suppress, federal researchers gave mice and rats massive doses of THC, looking for cancers or other signs of toxicity. The rodents given THC lived longer and had fewer cancers, “in a dose-dependent manner” (i.e. the more THC they got, the fewer tumors). NTP Technical Report On The Toxicology And Carcinogenesis Studies Of 1-Trans- Delta-9-Tetrahydrocannabinol, CAS No. 1972-08-3, In F344/N Rats And B6C3F Mice, Gavage Studies. See also, “Medical Marijuana: Unpublished Federal Study Found THC-Treated Rats Lived Longer, Had Less Cancer,” AIDS Treatment News no. 263, Jan. 17, 1997.

3) OOPS, MARIJUANA MAY PREVENT CANCER (PART III):
Researchers at the Kaiser-Permanente HMO, funded by NIDA, followed 65,000 patients for nearly a decade, comparing cancer rates among non-smokers, tobacco smokers, and marijuana smokers. Tobacco smokers had massively higher rates of lung cancer and other cancers. Marijuana smokers who didn’t also use tobacco had no increase in risk of tobacco-related cancers or of cancer risk overall. In fact their rates of lung and most other cancers were slightly lower than non-smokers, though the difference did not reach statistical significance. Sidney, S. et al. Marijuana Use and Cancer Incidence (California, United States). Cancer Causes and Control. Vol. 8. Sept. 1997, p. 722-728.

2) OOPS, MARIJUANA MAY PREVENT CANCER (PART IV):
Donald Tashkin, a UCLA researcher whose work is funded by NIDA, did a case-control study comparing 1,200 patients with lung, head and neck cancers to a matched group with no cancer. Even the heaviest marijuana smokers had no increased risk of cancer, and had somewhat lower cancer risk than non-smokers (tobacco smokers had a 20-fold increased lung cancer risk). Tashkin D. Marijuana Use and Lung Cancer: Results of a Case-Control Study. American Thoracic Society International Conference. May 23, 2006.

1) MARIJUANA DOES HAVE MEDICAL VALUE:
In response to passage of California’s medical marijuana law, the White House had the Institute of Medicine (IOM) review the data on marijuana’s medical benefits and risks. The IOM concluded, “Nausea, appetite loss, pain and anxiety are all afflictions of wasting, and all can be mitigated by marijuana.” While noting potential risks of smoking, the report added, “we acknowledge that there is no clear alternative for people suffering from chronic conditions that might be relieved by smoking marijuana, such as pain or AIDS wasting.” The government’s refusal to acknowledge this finding caused co-author John A. Benson to tell the New York Times that the government “loves to ignore our report … they would rather it never happened.” Joy, JE, Watson, SJ, and Benson, JA.

Worth Repeating: Over 50 Studies Show Cannabis is Medicine

​Welcome to Room 420, where your instructor is Mr. Ron Marczyk and your subjects are wellness, disease prevention, self actualization, and chillin’.


Worth Repeating
​By Ron Marczyk, R.N.
Health Education Teacher (Retired)
The quote below, from a news release, is a political statement that is based on incomplete and biased science. Remember, once science is politicized, it is no longer science.
“No sound scientific studies supported medical use of marijuana for treatment in the United States, and no animal or human data supported the safety or efficacy of marijuana for general medical use.”
Not true! An overwhelming number of studies exist to firmly support cannabis as all-purpose medicine and very possibly a strong candidate as a cure for cancer as was originally reported by the National Cancer Institute.
There has never been a single documented primary human fatality from overdosing on cannabis in its natural form in any amount. How’s that for safety!

In addition, cannabis can be vaporized or eaten in sweets, which takes the smoking issue off the table!  And as counter-intuitive as its sounds, evidence exists that cannabis offers a mild protective effect against cancer.

​ I would like to bring attention to the 50+ empirical studies (footnoted below) that may have been overlooked by the FDA in their “thoroughly analyzed search of all the relevant medical, scientific data” on medical cannabis.
“In 2001, the Food and Drug Administration (FDA) and the Drug Enforcement Administration thoroughly analyzed the relevant medical, scientific, and abuse data and concluded that marijuana continues to meet the criteria for placement in schedule I of the Controlled Substances Act. The Food and Drug Administration reiterated this determination in April 2006, stating in a news release:
“Marijuana is listed in Schedule I of the Controlled Substances Act (CSA), the most restrictive schedule. The Drug Enforcement Administration (DEA), which administers the CSA, continues to support that placement and FDA concurred because marijuana met the three criteria for placement in Schedule I under 21 U.S.C. 812(b)(1) (e.g., marijuana has a high potential for abuse, has no currently accepted medical use in treatment in the United States, and has a lack of accepted safety for use under medical supervision).
“Furthermore, there is currently sound evidence that smoked marijuana is harmful. A past evaluation by several Department of Health and Human Services (HHS) agencies, including the Food and Drug Administration (FDA), Substance Abuse and Mental Health Services Administration (SAMHSA) and National Institute for Drug Abuse (NIDA), concluded that no sound scientific studies supported medical use of marijuana for treatment in the United States, and no animal or human data supported the safety or efficacy of marijuana for general medical use. There are alternative FDA-approved medications in existence for treatment of many of the proposed uses of smoked marijuana.” (Source: justice.gov)
Empirically Based Evidence Supporting Medical Cannabis
NORML Foundation/Senior Policy Analyst
“Cannabinoids possess … anticancer activity [and may] possibly represent a new class of anti-cancer drugs that retard cancer growth, inhibit angiogenesis (the formation of new blood vessels) and the metastatic spreading of cancer cells.” So concludes a comprehensive review published in the October 2005 issue of the scientific journal Mini-Reviews in Medicinal Chemistry.
Not familiar with the emerging body of research touting cannabis’ ability to stave the spread of certain types of cancers? You’re not alone.
For over 30 years, US politicians and bureaucrats have systematically turned a blind eye to scientific research indicating that marijuana may play a role in cancer prevention — a finding that was first documented in 1974. That year, a research team at the Medical College of Virginia (acting at the behest of the federal government) discovered that cannabis inhibited malignant tumor cell growth in culture and in mice. According to the study’s results, reported nationally in an Aug. 18, 1974, Washington Post newspaper feature, administration of marijuana’s primary cannabinoid THC, “slowed the growth of lung cancers, breast cancers and a virus-induced leukemia in laboratory mice, and prolonged their lives by as much as 36 percent.”
Despite these favorable preclinical findings, US government officials dismissed the study (which was eventually published in the Journal of the National Cancer Institute in 1975), and refused to fund any follow-up research until conducting a similar — though secret — clinical trial in the mid-1990s. That study, conducted by the US National Toxicology Program to the tune of $2 million concluded that mice and rats administered high doses of THC over long periods experienced greater protection against malignant tumors than untreated controls.
Rather than publicize their findings, government researchers once again shelved the results, which only came to light after a draft copy of its findings were leaked in 1997 to a medical journal, which in turn forwarded the story to the national media.
Nevertheless, in the decade since the completion of the National Toxicology trial, the U.S. government has yet to encourage or fund additional, follow up studies examining the cannabinoids’ potential to protect against the spread cancerous tumors.
Fortunately, scientists overseas have generously picked up where US researchers so abruptly left off. In 1998, a research team at Madrid’s Complutense University discovered that THC can selectively induce apoptosis (program cell death) in brain tumor cells without negatively impacting the surrounding healthy cells. Then in 2000, they reported in the journal Nature Medicine that injections of synthetic THC eradicated malignant gliomas (brain tumors) in one-third of treated rats, and prolonged life in another third by six weeks.
In 2003, researchers at the University of Milan in Naples, Italy, reported that non-psychoactive compounds in marijuana inhibited the growth of glioma cells in a dose dependent manner and selectively targeted and killed malignant cancer cells.
The following year, researchers reported in the journal of the American Association for Cancer Research that marijuana’s constituents inhibited the spread of brain cancer in human tumor biopsies. In a related development, a research team from the University of South Florida further noted that THC can also selectively inhibit the activation and replication of gamma herpes viruses. The viruses, which can lie dormant for years within white blood cells before becoming active and spreading to other cells, are thought to increase one’s chances of developing cancers such as Karposis Sarcoma, Burkitts lymphoma, and Hodgkins disease.
More recently, investigators published pre-clinical findings demonstrating that cannabinoids may play a role in inhibiting cell growth of colectoral cancer, skin carcinoma, breast cancer, and prostate cancer, among other conditions. When investigators compared the efficacy of natural cannabinoids to that of a synthetic agonist, THC proved far more beneficial – selectively decreasing the proliferation of malignant cells and inducing apoptosis more rapidly than its synthetic alternative while simultaneously leaving healthy cells unscathed.
Nevertheless, US politicians have been little swayed by these results, and remain steadfastly opposed to the notion of sponsoring – or even acknowledging – this growing body clinical research, preferring instead to promote the unfounded notion that cannabis use causes cancer. Until this bias changes, expect the bulk of research investigating the use of cannabinoids as anticancer agents to remain overseas and, regrettably, overlooked in the public discourse.”
Thanks, Paul.
The following current research studies all provide overwhelming evidence that THC holds the promise of being a non-toxic multipurpose chemotherapy agent that may have anti-tumor action on many different types of cancer.
THC and synthetic cannabinoids both have similar action on CB1/2 receptors, and seem to work best in combination, just as ingesting cannabis as a whole plant produces its wide spectrum healing effects, such as relieving vomiting, being able eat, having no physical pain and being able to sleep. This is how the body heals itself.
Medical cannabis is a family of unique cannabinoids  that also have antiemetic effects, appetite stimulation, pain relief, and improved sleep, as reported by the National Cancer Institute:   http://www.cancer.gov/cancertopics/pdq/cam/cannabis/healthprofessional/page5
These four medically proven cancer treatment effects of cannabis on their own totally disprove the FDA statement, but with an anti-tumor effect added, as also reported by NCI, this plant becomes a “Swiss survival knife”of medicines.  Imagine that – one drug that treats five different medical conditions at once!
A quick search of Wikipedia yields the following five studies:
“Investigators at Madrid’s Complutense University, School of Biology, first reported that THC induced apoptosis (programmed cell death) in glioma cells in culture”[1a]
“Investigators followed up their initial findings, reporting that the administration of both THC and the synthetic cannabinoid agonist WIN55-212-2 induced a considerable regression of malignant gliomas in animals” [2b]
“Researchers again confirmed cannabinoids’ ability to inhibit tumor growth in animals in 2003″[3c]
“Most Recently investigators at the University of California, Pacific Medical Center reported that cannabinoids possess synergistic anti-cancer properties — finding that the administration of a combination of the plant’s constituents is superior to the administration of isolated compounds alone”[4d]
“Consequently, many experts now believe that cannabinoids may represent a new class of anticancer drugs that retard cancer growth, inhibit angiogenesis and the metastic spreading of cancer cells [5e] and have recommended that at least one cannabinoid, cannabidiol, now be utilized in cancer therapy.”

Gliomas/Brain Cancer
by Paul Armentano
NORML Foundation/Senior Policy Analyst
Gliomas (tumors in the brain) are especially aggressive malignant forms of cancer, often resulting in the death of affected patients within one to two years following diagnosis. There is no cure for gliomas and most available treatments provide only minor symptomatic relief.
A review of the modern scientific literature reveals numerous preclinical studies and one pilot clinical study demonstrating cannabinoids’ ability to act as anti-neoplastic agents, particularly on glioma cell lines.
Writing in the September 1998 issue of the journal FEBS Letters, investigators at Madrid’s Complutense University, School of Biology, first reported that delta-9-THC induced apoptosis (programmed cell death) in glioma cells in culture.[1] Investigators followed up their initial findings in 2000, reporting that the administration of both THC and the synthetic cannabinoid agonist WIN 55,212-2 “induced a considerable regression of malignant gliomas” in animals.[2] Researchers again confirmed cannabinoids’ ability to inhibit tumor growth in animals in 2003.[3]
That same year, Italian investigators at the University of Milan, Department of Pharmacology, Chemotherapy and Toxicology, reported that the non-psychoactive cannabinoid, cannabidiol (CBD), inhibited the growth of various human glioma cell lines in vivo and in vitro in a dose dependent manner. Writing in the November 2003 issue of the Journal of Pharmacology and Experimental Therapeutics Fast Forward, researchers concluded, “Non-psychoactive CBD … produce[s] a significant anti-tumor activity both in vitro and in vivo, thus suggesting a possible application of CBD as an anti neoplastic agent.”[4]
In 2004, Guzman and colleagues reported that cannabinoids inhibited glioma tumor growth in animals and in human glioblastoma multiforme (GBM) tumor samples by altering blood vessel morphology (e.g., VEGF pathways). Writing in the August 2004 issue of Cancer Research, investigators concluded, “The present laboratory and clinical findings provide a novel pharmacological target for cannabinoid-based therapies.”[5]
Five Other Studies Found on pub.Med. Relating to Gliomas
1. Cannabinoid action induces autophagy-mediated cell death through stimulation of ER stress in human glioma cells.
J Clin Invest. 2009 May;119(5):1359-72     Department of Biochemistry and Molecular Biology, Complutense University, Madrid, Spain.
FINDINGS:
Autophagy can promote cell survival or cell death, but the molecular basis underlying its dual role in cancer remains obscure. Here we demonstrate that delta(9)-tetrahydrocannabinol (THC), the main active component of marijuana, induces human glioma cell death through stimulation of autophagy.
The finding of this study describe a mechanism by which THC can promote the autophagic death of human and mouse cancer cells and provide evidence that cannabinoid administration may be an effective therapeutic strategy for targeting human cancers.

FINDINGS:
The development of new therapeutic strategies is essential for the management of gliomas, one of the most malignant forms of cancer. We have shown previously that the growth of the rat glioma C6 cell line is inhibited by psychoactive cannabinoids.  These compounds act on the brain and some other organs through the widely expressed CB(1) receptor. By contrast, the other cannabinoid receptor subtype, the CB(2) receptor, shows a much more restricted distribution and is absent from normal brain. Cannabinoid receptor expression was subsequently examined in biopsies from human astrocytomas.
A full 70 percent (26 of 37) of the human astrocytomas analyzed expressed significant levels of cannabinoid receptors. Of interest, the extent of CB(2) receptor expression was directly related with tumor malignancy.

FINDINGS:
Delta 9-Tetrahydrocannabinol, the main active component of marijuana, induces apoptosis of transformed neural cells in culture. Here, we show that intratumoral administration of Delta9-tetrahydrocannabinol and the synthetic cannabinoid agonist WIN-55,212-2 induced a considerable regression of malignant gliomas in Wistar rats and in mice deficient in recombination activating gene.
Cannabinoid treatment did not produce any substantial neurotoxic effect in the conditions used. Experiments with two subclones of C6 glioma cells in culture showed that cannabinoids signal apoptosis by a pathway involving cannabinoid receptors, sustained ceramide accumulation and Raf1/extracellular signal-regulated kinase activation. These results may provide the basis for a new therapeutic approach for the treatment of malignant gliomas.

Abstract
Gliomas, in particular glioblastoma multiforme or grade IV astrocytoma, are the most frequent class of malignant primary brain tumours and one of the most aggressive forms of cancer. Current therapeutic strategies for the treatment of glioblastoma multiforme are usually ineffective or just palliative. During the last few years, several studies have shown that cannabinoids — the active components of the plant Cannabis sativa and their derivatives –slow the growth of different types of tumours, including gliomas, in laboratory animals.
Remarkably, cannabinoids kill glioma cells selectively and can protect non-transformed glial cells from death. These and other findings reviewed here might set the basis for a potential use of cannabinoids in the management of gliomas.

FINDINGS:
Delta 9-Tetrahydrocannabinol (THC) and other cannabinoids inhibit tumour growth and angiogenesis in animal models, so their potential application as antitumoral drugs has been suggested. However, the antitumoral effect of cannabinoids has never been tested in humans. Here we report the first clinical study aimed at assessing cannabinoid antitumoral action, specifically a pilot phase I trial in which nine patients with recurrent glioblastoma multiforme were administered THC intratumorally.
The patients had previously failed standard therapy (surgery and radiotherapy) and had clear evidence of tumour progression. The primary end point of the study was to determine the safety of intracranial THC administration. We also evaluated THC action on the length of survival and various tumour-cell parameters. A dose escalation regimen for THC administration was assessed. Cannabinoid delivery was safe and could be achieved without overt psychoactive effects. Median survival of the cohort from the beginning of cannabinoid administration was 24 weeks (95% confidence interval: 15-33). 9-Tetrahydrocannabinol inhibited tumour-cell proliferation in vitro and decreased tumour-cell Ki67 immunostaining when administered to two patients. The fair safety profile of THC, together with its possible antiproliferative action on tumour cells reported here and in other studies, may set the basis for future trials aimed at evaluating the potential antitumoral activity of cannabinoids.
CANCER IN GENERAL 
From Paul Armentano at NORML:
In addition to cannabinoids’ ability to moderate glioma cells, separate studies demonstrate that cannabinoids and endocannabinoids can also inhibit the proliferation of other various cancer cell lines, including breast carcinoma,[11-15] prostate carcinoma,[16-18] colorectal carcinoma,[19] gastric adenocarcinoma,[20] skin carcinoma,[21] leukemia cells,[22-23]neuroblastoma,[24] lung carcinoma,[25-26] uterus carcinoma,[27] thyroid epithelioma,[28] pancreatic adenocarcinoma,[29-30], cervical carcinoma,[31] oral cancer,[32] biliary tract cancer (cholangiocarcinoma)[33] and lymphoma.[34-35]
Studies also indicate that the administration of cannabinoids, in conjunction with conventional anti-cancer therapies, can enhance the effectiveness of standard cancer treatments.[36] Most recently, investigators at the University of California, Pacific Medical Center reported that cannabinoids possess synergistic anti-cancer properties — finding that the administration of a combination of the plant’s constituents is superior to the administration of isolated compounds alone.[37]
Consequently, many experts now believe that cannabinoids “may represent a new class of anticancer drugs that retard cancer growth, inhibit angiogenesis and the metastatic spreading of cancer cells.”[38-39]

FINDINGS: One of the most exciting areas of current research in the cannabinoid field is the study of the potential application of these compounds as antitumoral drugs. Here, we describe the signaling pathway that mediates cannabinoid-induced apoptosis of tumor cells. By using a wide array of experimental approaches, we identify the stress-regulated protein p8 as an essential mediator of cannabinoid antitumoral action. Activation of this pathway may constitute a potential therapeutic strategy for inhibiting tumor growth.

FINDINGS:
• Cannabinoids, the active components of the cannabis plant, have some clinical merit both as an anti-emetic and appetite stimulant in patients. Recently, interest in developing cannabinoids as therapies has increased following reports that they possess anti-tumour properties.
• Research into cannabinoids as anti-cancer agents is in its infancy, and has mainly focused on the pro-apoptotic effects of this class of agent. Impressive anti-cancer activities have been reported; actions that are mediated in large part by disruptions to ubiquitous signalling pathways such as ERK and PI3-K.
• However, recent developments have highlighted a putative role for cannabinoids as anti-inflammatory agents. Chronic inflammation has been associated with neoplasia for sometime, and as a consequence, reducing inflammation as a way of impacting cancer presents a new role for these compounds. This article reviews the ever-changing relationship between cannabinoids and cancer, and updates our understanding of this class of agent. Furthermore, the relationship between chronic inflammation and cancer, and how cannabinoids can impact this relationship will be described.

FINDINGS:
Cannabinoids are a class of pharmacologic compounds that offer potential applications as antitumor drugs, based on the ability of some members of this class to limit inflammation, cell proliferation, and cell survival. In particular, emerging evidence suggests that agonists of cannabinoid receptors expressed by tumor cells may offer a novel strategy to treat cancer. Here, we review recent work that raises interest in the development and exploration of potent, nontoxic, and nonhabit forming cannabinoids for cancer therapy.

FINDINGS:
Cannabinoids (the active components of Cannabis sativa) and their derivatives have received renewed interest in recent years due to their diverse pharmacological activities. In particular, cannabinoids offer potential applications as anti-tumour drugs, based on the ability of some members of this class of compounds to limit cell proliferation and to induce tumour-selective cell death.
Although synthetic cannabinoids may have pro-tumour effects in vivo due to their immunosuppressive properties, predominantly inhibitory effects on tumour growth and migration, angiogenesis, metastasis, and also inflammation have been described. Emerging evidence suggests that agonists of cannabinoid receptors expressed by tumour cells may offer a novel strategy to treat cancer. In this chapter we review the more recent results generating interest in the field of cannabinoids and cancer, and provide novel suggestions for the development, exploration and use of cannabinoid agonists for cancer therapy, not only as palliative but also as curative drugs.

FINDINGS:
Cannabinoids, the active components of the hemp plant Cannabis sativa, along with their endogenous counterparts and synthetic derivatives, have elicited anti-cancer effects in many different in vitro and in vivo models of cancer. While the various cannabinoids have been examined in a variety of cancer models, recent studies have focused on the role of cannabinoid receptor agonists (both CB(1) and CB(2)) in the treatment of estrogen receptor-negative breast cancer. This review will summarize the anti-cancer properties of the cannabinoids, discuss their potential mechanisms of action, as well as explore controversies surrounding the results.

BACKGROUND:
Cannabinoids, in addition to having palliative benefits in cancer therapy, have been associated with anticarcinogenic effects. Although the antiproliferative activities of cannabinoids have been intensively investigated, little is known about their effects on tumor invasion. we found that ..

Increased expression of TIMP-1 mediates an anti-invasive effect of cannabinoids. Cannabinoids may therefore offer a therapeutic option in the treatment of highly invasive cancers.

FINDINGS:
Cannabinoids, the active components of Cannabis sativa  (marijuana) and their derivatives have received renewed interest in recent years due to their diverse pharmacologic activities such as cell growth inhibition, anti-inflammatory effects and tumor regression.
Here we show that expression levels of both cannabinoid receptors, CB1 and CB2, are significantly higher in CA-human papillomavirus-10 (virally transformed cells derived from adenocarcinoma of human prostate tissue), and other human prostate cells LNCaP, DUI45, PC3, and CWR22Rnu1 than in human prostate epithelial and PZ-HPV-7 (virally transformed cells derived from normal human prostate tissue) cells. WIN-55,212-2 (mixed CB1/CB2 agonist) treatment with androgen-responsive LNCaP cells resulted in a dose- (1-10 micromol/L) and time-dependent (24-48 hours) inhibition of cell growth, blocking of CB1 and CB2 receptors by their antagonists SR141716 (CB1) and SR144528 (CB2) significantly prevented this effect. Extending this observation, we found that WIN-55,212-2 treatment with LNCaP resulted in a dose- (1-10 micromol/L) and time-dependent (24-72 hours) induction of apoptosis (a), decrease in protein and mRNA expression of androgen receptor (b), decrease in intracellular protein and mRNA expression of prostate-specific antigen (c), decrease in secreted prostate-specific antigen levels (d), and decrease in protein expression of proliferation cell nuclear antigen and vascular endothelial growth factor (e). Our results suggest that WIN-55,212-2 or other non-habit-forming cannabinoid receptor agonists could be developed as novel therapeutic agents for the treatment of prostate cancer.

FINDINGS:
Deregulation of cell survival pathways and resistance to apoptosis are widely accepted to be fundamental aspects of tumorigenesis. As in many tumours, the aberrant growth and survival of colorectal tumour cells is dependent upon a small number of highly activated signalling pathways, the inhibition of which elicits potent growth inhibitory or apoptotic responses in tumour cells. Accordingly, there is considerable interest in therapeutics that can modulate survival signalling pathways and target cancer cells for death.
There is emerging evidence that cannabinoids, especially Delta(9)-tetrahydrocannabinol (THC), may represent novel anticancer agents, due to their ability to regulate signalling pathways critical for cell growth and survival. Here, we report that CB1 and CB2 cannabinoid receptors are expressed in human colorectal adenoma and carcinoma cells, and show for the first time that THC induces apoptosis in colorectal cancer cells. These data suggest an important role for CB1 receptors and BAD in the regulation of apoptosis in colorectal cancer cells. The use of THC, or selective targeting of the CB1 receptor, may represent a novel strategy for colorectal cancer therapy.
