The Man Who Discovered THC

The HIGH TIMES Interview with Dr. Raphael Mechoulam


By Nico Escondido

Mechoulam The Man

The history of Israel marks it as a place of intense spirituality for many religions, most notably in Jewish, Christian and Islamic cultures. Ironically, a much more recent counter-culture can also point to the Holy Land as a major component of its heritage, not to mention the ground zero, of sorts, of the modern medical-marijuana movement.

In 1964, at the Weizmann Institute of Science in Rehovot, Israel, Dr. Raphael Mechoulam – along with his colleagues, Dr. Yehiel Gaoni and Dr. Haviv Edery – succeeded in the very first isolation and elucidation of the active constituent of cannabis, D9-tetrahydrocannabinol, also known as THC. The discovery of the THC compound – now almost 50 years ago – started a revolution in thinking about cannabis that carries on to this day.

Dr. Mechoulam is currently a professor of medicinal chemistry and natural products at the Hebrew University of Jerusalem. His total synthesis of THC, as well as other cannabinoids such as cannabidiol (CBD), is the cornerstone of the burgeoning medical-cannabis industry. Furthermore, his major contributions in the field of organic chemistry and the interaction of human and plant biology have led to the discovery of cannabinoid receptors in the human brain and the endocannabinoid system in the human body.

Dr. Mechoulam was kind enough to give his time for an exclusive interview with HIGH TIMES at his university laboratory in Jerusalem. It is very plausible that Dr. Mechoulam may one day win a Nobel Prize for his work and contributions in these fields. But it is his courage in introducing a previously little-researched plant to the world – a plant that is rapidly proving itself as nothing short of miraculous – that make Dr. Raphael Mechoulam The Man.

Let’s start at the beginning. Tell us a little bit about what the marijuana scene was like when you began working with cannabis.


It was a South American problem, really. Nobody was smoking it in the US except for a few musicians – a few black musicians, you know. Incidentally, it seems to have something to do with – well, ah, how can I explain that? Maybe understanding the music better, or hearing the music better. Especially jazz musicians. But that was it.

So then how did your research with cannabis come about exactly?


Well, when my friend [Dr. Yehiel Gaoni] and I started working on it, I was 32 years old. And when I initially asked for a grant, I sent it out to the NIH [National Institutes of Health] in the US. I asked for a research grant, but they said, “No, no, no. It is not in our interest. Let us know when you have something more relevant for us.” But then, soon after we isolated THC, they decided it was relevant work.

And so, when we started working, essentially nobody was working on that – and the reasons were probably legal. You couldn’t really do it in the US, at least, and the US was, at that time, the only place that there was any serious research going on … and the UK. The laws were such that you had to have guards all over the place. You can’t see an American professor with graduate students and having three guards around him.

So we had just isolated THC and, to the world’s surprise, they [NIH] came over to see our work. We had 10 grams of THC isolated from hashish, so they took it back with them, and most of the initial research in the US was done with our THC.

And so here [in Israel] we had no problem working because, you know, here – well, the laws are the same, but the application of the law is a little bit different. They knew I was not going to go outside and start selling marijuana; they didn’t assume that I will do that. We were able to work on it for a couple of years, though essentially nobody else was around, so we published quite a bit – and that was in the mid-’60s. So that was it.

We know that your interest lies in the connection between chemistry and biology, but what was the intent for you with cannabis? Did you think back then that there was medicinal value in cannabis?


No, no, it’s a natural product. If you look at the other illicit drugs that are throughout the world, morphine came out of opium or poppy plants, and cocaine came out of cocoa leaves – and these were discovered 150 years ago. Morphine was isolated in the early 19th century, and cocoa and cocaine in the middle 19th century. And surprisingly, THC – the active component of cannabis – was not known, which seemed very strange.

And I know why it was not isolated: because the techniques were very complicated. See, morphine and cocaine are so-called alkaloids, namely a natural product that contains a nitrogen [atom] on the molecule, and it can give us salt; it precipitates as a salt. And so you have salt: Cocaine is a salt, morphine is a salt – very easy to prepare. It turned out that THC does not have a nitrogen, and it is present in a mixture of compounds – we know that there are about 60 of them now. And they didn’t have the techniques to isolate them in the past. So a few people tried here and there, actually some very good people – one of them [Lord Alexander Todd] got the Nobel Prize for something else. But they never succeeded in isolating the pure substance, and so they never knew whether they had one compound or many compounds, and so on.

So the impetus was really that cannabis was being used and you knew of its use, yet there was no real research? I’m trying to figure out why it was cannabis that you guys went to instead of, say, boswellia or some other plant.


Well, my interest is in natural products that have some biological activity, and there are a huge number of natural products and plants that have activities. I probably have the best library, at least in Israel, with books and publications on natural products, on plants – you name it, we can find it. And let’s say, just for the fun of it, here is this dictionary of plants found in southern and eastern Africa – all plants with medicinal properties. So you can pick out any one of them and just open it – say buchu. Okay, it is a natural product. It lists some of the known herbal remedies. It’s also used for relief of rheumatism.

Is it true? Is it not true? I just opened the book – I have no idea. So there are thousands of them, and you have to decide what you want to work on, and one has to choose something that makes sense. And here I know that this [cannabis] is something that makes sense – namely that it has a compound within the plant that has obviously active products – and it turned out to be interesting.

But at that time, you didn’t know about cannabinoid receptors in the human body?


No, as a matter of fact, that came much later. You see, there are mistakes in science, too. People didn’t realize that there were receptors. As a matter of fact, an excellent group in Oxford with Sir Bill Paton, Sir William – probably pharmacologist number one in the world, a good friend of mine – he had said there were no receptors, and for very good reasons. Those reasons are probably too complicated to explain for a journal or a magazine ….

Well, try us anyway.


Basically, the reasons were, you see, when something [like a molecule] binds to a receptor, it has to have a specific stereochemistry. You have two hands, they’re identical … well, they’re not identical: If you put one on top of the other, they’re just the opposite – they are mirror images of each other, they are not identical. So it is true for many of the natural products: They can have two images, mirror images, but only one of them is the natural product – the other probably doesn’t even exist. We could synthesize it, but it’s not the natural product. In this case, the natural product [THC] has the activity. If both of them have activity, then chances are it does not bind to anything biological like a receptor, an enzyme or something like that, because the receptor itself is asymmetric.

So if this is the receptor [holding up one hand], you can have only one thing binding to it, but not its mirror image … only one of them. And it turned out that both of them were active – both mirror images of THC. One of them was natural; the other one we had synthesized; both of them worked. So Bill said, “No, it can’t be. There cannot be a THC receptor.”

Well, it turned out that they were not very good organic chemists. They were buying the raw material, the starting material [for their testing], that already had the two images – with the mirror image being synthetic – and you cannot separate them at that point. So if you have even 20 percent of the wrong stereoisomer, then you end up with a completely wrong stereoisomer. So both compounds tested as active, and thus they thought there would not be a human receptor.

But then we actually did some better work, I think, as we found out that it was not true – because only one mirror image was, in fact, active [laughing]. So, for the 20 years since we discovered the chemical material [THC], we all went along the wrong pathway! So when we discovered that only one of them was active, another good friend of mine in St. Louis finally found the first receptor.

Dr. Howlett?


Yes, correct, Dr. Allyn Howlett. And so Dr. Howlett found the receptor … and, basically, if you have a receptor in the body, it’s not because there is a plant out there. It doesn’t work that way – it works only because there is something in your body which will activate that receptor. So we went after those compounds that activated it. And we found the compound in the brain that activated it.



[Also known as N-arachidonoylethanolamine or AEA, anandamide is a naturally occurring cannabinoid produced in the human body for use as a neurotransmitter. It was first isolated and described by the Czech analytical chemist Lumír Ondřej Hanuš and the American molecular pharmacologist William Anthony Devane in Dr. Mechoulam’s Hebrew University laboratory in 1992. The name is derived from the Sanskrit word ananda, which means “bliss” or “delight.”]


We know there are so many different cannabinoids – THC, CBD, CBN, CBG, etc. Do they all bind with the CB1 and CB2 receptors?


Only THC – and only THC is psychoactive. So, as it binds to the CB1 receptor, it causes the activities that are known as cannabis activities. That’s it, period. None of the others – well, at least not significantly; there are a little bit here and there – but no other compound out of the 60, or whatever they are, binds.

There is a lot of interest now in the United States within the medical movement to find cannabis strains that are high in cannabidiol or CBD.

Well, this is something that I made a big fuss about. You see, with illicit cannabis – which is a huge, huge thing in the States – there is no interest in having anything else but very high levels of THC, because THC is the compound that attaches [to the brain’s cannabinoid receptors] and is psychoactive. Nobody’s interested in CBD because it causes no activity. But it is – from a medical point of view – very important, because it’s an anti-inflammatory and does all kinds of interesting things. It even blocks some of the undesirable effects of THC.

Under THC – of course, you’ve never smoked marijuana [laughing] – but seriously, when you have not smoked and then do and the doses are high, you may have an acute loss of memory. I mean, you don’t remember everything as it should be remembered. And if you have enough CBD, you block that kind of memory loss.

I was interested in the cannabidiol. But if you look at the cannabis that’s being grown illicitly in the US – and it’s a small business [chuckling], probably the number one agricultural product, I’ve been told, in terms of money – there is little or no CBD in there.

There was a medical meeting recently in the US, and I went there. I gave the opening lecture, and I told them you can’t [not have CBD]. You have to have CBD, and that’s it. So they’re trying to get CBD now in medical marijuana, which is the right thing to do.

A lot of the people that we meet around the world are searching for these CBD-rich strains. Now, with the lab testing going on in the medical community – you know, with gas-chromotography machines and mass spectrometers – people are really trying to look closely at it. But compared to THC, the CBD and CBN results are usually negligible; the CBD is always less than 1 percent. However, they’ve now found two or three strains that have around 8 percent CBD.

What do you mean, they have to find the strains? I mean, in Lebanon, they have been growing cannabis for the last, I don’t know, 300, 400 years or whatever. Lebanese hashish contains 5 percent THC and about 5 percent CBD. So go to Lebanon, take a strain from there, period – why make a fuss? We isolate cannabidiol from hashish. We don’t synthesize it; we isolate it. We do a lot of work on CBD.

So we go to the police, we pick up a couple of kilos of hashish – not marijuana. We pick up several kilos of hashish, isolate the cannabidiol and get a nice crystalline product. THC is an oil; CBD is nicely crystally. And then we make all kinds of things from CBD. So why make a fuss? Go to Lebanon and buy a few strains. Or in India – there are a lot of strains in India.

And where does the CBD bind to if not the CB1 and CB2 receptors?


Oh, no, it does not bind …. Well, it’s more complicated – it does not bind to the cannabinoid receptor. It does all kinds of other things. It prevents adenosine – that’s another compound in the brain – from going where it should go. It also acts on something else, on serotonin. We have seen, for example, some work we did here on a disease which has a nice name, but it’s a sinful disease: hepatic encephalopathy. Now hepatic encephalopathy, if you are drunk – really seriously drunk – then you have hepatic encephalopathy. Alcoholics can destroy the liver, and liver failure then causes central-nervous-system changes. They have destroyed their liver, and after destroying the liver, they start destroying the brain. That’s hepatic encephalopathy.

Now, we can cause hepatic encephalopathy to mice [in lab tests] and then see the changes that happen in the brain. They can’t walk well and all kinds of other things. We give them CBD, and it improves their conditions tremendously. And that was through one of the serotonin receptors. Now, serotonin is a nice compound – it has 15 or 16 receptors, maybe more. But this receptor we used was serotonin receptor 1A.

So [CBD] works in a variety of ways and, surprisingly, it has no side effects. Very strange. I would have assumed that something that has so many pathways to it, then it will have some side effects – and it has no side effects. As a matter of fact, it is completely nontoxic. One of the least toxic compounds that I’ve seen is cannabidiol – very strange.

Many years ago, NIH thought that they should look at the toxicity of CBD, because people were smoking both THC and CBD, both of which are present in marijuana: “Well, we know a little bit about THC; we know nothing about cannabidiol. Does it cause anything” – I don’t know, destroy the brain or whatever? And so they did a very thorough study of the toxicity of CBD and found essentially none … which is very positive.

NIH is probably one of the best institutions in the world. They really do excellent work, and I can only admire the people who decided to set up NIH, I don’t know, 30, 40 years ago.

Then what would be your guess as to why, with the NIH being in the United States, why the US has such a hard time getting federal regulation for medicinal cannabis? Right now it’s only state by state, and the federal government is very adamant about not allowing marijuana to become legal for medicine. Yet, like you said, there is all this great research going on over there, they are at the forefront of a lot of this, so where is the gap here? 

There is a huge amount of research going on – but I’m not sure, because many of the states do have regulations for medical marijuana. And the president actually made some noise that he wants to do it – to allow the federal government to do it. Now, why didn’t he? Probably he didn’t have enough power to do it, because chances are that these regulations have to go through the various committees and so on, and he was not sure he could get enough support.

Every administration has people where Mr. A does that and Mr. B does this and then they have a fight. Mr. B is the person that wins, and that’s it – it’s like all administrations. I was head of the university many years ago; I know that that’s the way it works.

Politics ….


Yes, exactly.

But wasn’t it the politicians who were responsible for all of this? Didn’t one politician spur the NIH’s decision to give you the research grants after you first isolated THC?


Yeah, well, they [NIH] didn’t have a single grant on cannabis at that time, but the National Institute of Mental Health did, I think. As I said earlier, the NIH wrote me that they don’t want to, they won’t give me money, because it’s not interesting or relevant. And then, all of a sudden, I get a phone call from the head of pharmacology at NIH, and they’re now interested. So I asked him: “What happened, all of a sudden, that you have great interest?” Well, it turned out that a senator had called NIH – his son smoked pot, and he wanted to know whether it would destroy his mind!

And just like that, the government got NIH to change direction. They don’t want to fight the senators because they need their support, and they looked around and [said] “Aha!” – they don’t support grants on marijuana, so they asked me if I was still working. We had just isolated THC, and that was it.

Do you remember the name of the senator? We can send him flowers.


No, but even if I did … I wouldn’t tell you. Anyway, he’s probably dead by now.

A Brief Overview of Concentrates

Concentrates are just that, the active ingredients (THC & Cannabinoids) that has been extracted from the marijuana plant material. There are several methods of extraction. The quality of the concentrate can range from poor to extremely high. Using different types of tools and methods yields different concentrates, viscosities and potencies

Concentrates can be extracted several ways with the three most common being: cold water, BHO (Butane hash oil) and CO2. Medical marijuana patients are using more and more concentrates today mostly because of their high THC and Cannabinoid content and that they are relatively easy to find in collectives at reasonable prices. Below is a brief introduction of the three more popular extraction methods and types of concentrates they produce. Hit the jump for more information on concentrates.

Cold water extraction produces a concentrate that ranges in color from light golden beige to black depending on the purity. Generally the lighter the color, the purer melt you will have (no residue). Cold water concentrates are better known as bubble hash and should be dry. It can come in different consistencies from a powder to putty like texture. The concentrate and process for cold water extraction is all organic because it only uses ice and cold water, which makes it great to use in any culinary dishes.

The second most popular extraction method is BHO or Butane Hash Oil extraction and the process uses butane to pass over the marijuana plant material. Neither the concentrate nor the process is considered organic. Although it’s not organic, BHO concentrates are used in many culinary dishes. It’s easily identified because it’s not oily like the cold water extractions. You may hear BHO’s go by other names such as: goo, earwax, wax, glass, shatter and moon rocks at collectives and dispensaries.

The last method of concentrate extraction mentioned here is CO2 extraction and it’s very similar to BHO extraction except that dry ice isn’t flammable. Dry ice is shaken over the marijuana plant material or added to a bubble hash process to knock off the gland heads from the buds. The heads stay intact because of the cold temperatures. The finished product is a fine crystal powder and must be kept frozen or very cold or else it will liquefy or turn into a big blob at room temperature. The concentrate is also known as Crystals, Gold Dust, 95%THC and Sugars.

Concentrates can vary in strength and completely depend on the quality of the strain used when making them. They can be consumed by either ingesting them, smoking them with flowers or by using any of the custom smoking devices that have been created such as skillets, globes, nails, smashers and vaporizers.

How To: Make Weed Wine (Recipe)

Cannabis is often added to alcohol to make a quick and effective drink that will keep. However, we suggest consuming this red wine concoction on the night of making, and of course sharing it. This simple recipe serves 6-9 people and is an easy way to rid yourself of any trimmed leaves you may otherwise be discarding.


  • 1 bottle of good red wine
  • 4 cloves
  • 1/4 teaspoon of nutmeg
  • 1/4 teaspoon of cardamom
  • 1/2 teaspoon ground cinnamon
  • an orange to stick the cloves into
  • 28 grams (1 ounce) of trimmed cannabis leaves


Combine ingredients in a large pan and warm gently for 2 hours. Then strain and serve.

  • 1 French baguette
  • 1 ½ tbsp. butter
  • 3 tbsp. cannabutter
  • 4 eggs
  • 1 cup milk
  • ¼ cup sugar
  • 3 tbsp. maple syrup
  • 1 tsp. vanilla extract
  • ½  tsp. salt
  • powdered sugar


Lightly butter a 13 by 9-inch (32.5 by 23-cm) baking dish.  Cut the baguette crosswise at an angle into 8 slices. Each should be about ¾ inch (2 cm) thick.  Using a small bowl, cream the  pair of butters together until thoroughly combined.  Now spread the butter onto a single side of each of your 8 slices and then arrange them butter side up in your prepared baking dish.

Next, whisk together the eggs, sugar, milk, syrup, vanilla, and salt. Pour the mixture over the bread and press the slices down into it before covering the dish and allowing it to refrigerate for 8 hours.

When ready to cook, preheat your oven to 350°F (180°C). Once heated, place the uncovered baking dish in the oven and bake for 45 minutes or until the tops are golden brown. Dust them with powdered sugar and serve.
