Chapter 1: What is the main topic discussed in this episode?
Oh hey, it's the lady at the diner weeping into her hash browns, Sally Ward. Pack in as much info right now and let's spark some discussion about weed. The psychology, the botany, the chemistry, the neurology, the legality, and the methodology. I.e. do you hold it in your lungs until you choke? Why do edibles sometimes feel like you will be high until you become dead?
And are any of those tinctures at crystal shops worth it? I tracked down one of the world's best researchers on this. Oh, so excited. Studied biopsychology and anthropology, got a PhD in psychology, went on to do a postdoc in human behavioral pharmacology at Columbia. They're now a professor and the vice chair for research. and the Department of Psychiatry and Biobehavioral Sciences at UCLA.
They're the director of the UCLA Center for Cannabis and Cannabinoids. I was so committed to interviewing this particular person that I waited three years until the scheduling worked out. Every week in our ology staff meeting, I would ask, have we heard back? When will my dreams come true? Finally, they did. And on a Friday afternoon a few weeks ago, I braved campus parking.
and a 90-degree February afternoon, and soon you will hear the results.
Chapter 2: What are the differences between edibles and pre-rolls?
And because we can't discuss the present without a little sprinkling of the past, I also tracked down a wonderful second expert, a sociocultural anthropologist and professor of anthropology at Smith College, and sat in a sunny conference room to ask about their experience both personally and academically researching the social stigmas and attitudes about this plant and
and how they've changed over time in regard to both recreational and medicinal marijuana. Now, I felt you bristle, some of you. Even the word marijuana is contentious. Marijuana is a word that has blurry origins. It may have come from a Central American indigenous term,
Although it wasn't widely grown or used in that part of the world until after Spanish colonization, others say marijuana was coined by anti-drug propagandists who wanted to blame it as a plague to the moral fiber of the US by way of immigration from Mexico. But as it stands, it's the most common word for the psychoactive buds of the plant, cannabis sativa.
Although cannabis as a term is edging that out. And cannabis comes from this ancient, ancient Eastern Iranic people, meaning cannabis. Now, the current legality, it gets very semantic, but hemp is different from marijuana, but both are cannabis sativa.
Now, hemp, it's the same species, but that has less than 0.3% THC, while marijuana refers to cultivars of cannabis with enough THC to be intoxicating when it's smoked or heated or refined. So federal law uses marijuana as a legal term to denote intoxicating plants. I'm already in the weeds with this. And we took two interviews.
We folded them into a two-parter because this is such a huge, interesting, contentious topic socially and scientifically. Honestly, I'm going to cover as much as I can and we've got a part two coming. But anyway, let's first say a quick thank you to patrons of Ologies who make this show possible and submit questions to the guests ahead of time.
Part two is entirely your questions and they are sharp and smart and thoughtful. So stay tuned for that next week. Also, if you need Ologies merch and you do, get yourself a shirt or a tote at ologiesmerch.com. Also, reminder, we have Smologies episodes that are shorter and kid-friendly. They're in their own feed, wherever you get podcasts.
Also, thank you to reviewers who, for no money, help us out so much by simply leaving a review. I read them all. And as proof, thank you this week to... who wrote, when I was a little girl, there was a diagram of a beaver dam at our nature center, and I so badly wanted to live there. It just seems so safe and cozy. Listening to ologies gives me that same feeling.
And sir, this honestly is one of the best compliments I've ever received. Also, newts in a human suit. Glad you liked the New to Brink episode. Ready to review. Also, thank you to sponsors of the show who enable us to donate to a cause each week.

Chapter 3: How has the history of cannabis influenced modern perceptions?
So, you know, opioids, cocaine, those kinds of psychoactive substances. And so I got my graduate degree studying animal models of addiction or substance use disorders. And I was really focused on opioids because opioids are interesting. They can be a very effective therapy for pain, but we also know that they're very addictive.
And so what are some of these variables that contribute to the therapeutic side or might push it to the harm addiction side? And so I spent a lot of time thinking about that. And totally serendipitously, I was thinking about where I was going to do my postdoctoral fellowship. And I ended up at Columbia University.
And at Columbia, they were doing the human counterpart of what we do in animal studies, where they were trying to understand the effects of these psychoactive substances that people use and might develop addiction to. And they were answering questions that...
People really want to know, but are very rarely answerable because essentially we want to know what are the effects of these psychoactive drugs like cocaine and opioids. The real way to know is to actually give the substance to somebody and measure the effects and compare it to a placebo, right?
But- Dr. Cooper says it's very difficult as one might imagine to just willy nilly give people drugs with known and potentially deadly side effects in an ethical manner. Review boards are like, that's a no, I fear. But it got her so excited about applying some animal models to the human neuroscience that could lead to ethical trials to improve public health and impact policy in a
Since many laws are ideally based on solid peer-reviewed studies, how does the research really reflect what is harmful and what's helpful? What an exciting dilemma thought the future Dr. Cooper.
So around that time, I joined Columbia. It was a very hard transition moving from animal to human research. And during that time, states started legalizing cannabis for medical purposes. So California legalized cannabis for medical purposes back in 1996. And other states were pretty slow to come on board.
But at that point in time, in 2007, a couple of states had started legalizing cannabis for medical purposes. And... This was really interesting to me because it's, you know, pharmacology in action. And I was in a lab that was studying the negative effects of cannabis.

Chapter 4: What role do cannabinoids play in the endocannabinoid system?
And here we're having legislation being passed to allow people to use it for medical purposes. So I became interested in understanding, like, where was the science that was leading this public policy? The implication to non-scientists is essentially, oh, cannabis is actually therapeutic for these indications, right?
Mm-hmm.
And so I started doing research and realizing very quickly that the policies were not at all guided by science.
So a decade ago, at least in the U.S., policy was like, yeah, man, go for it. But science was a little lacking at the time. And again, back in 2007, a handful, just 12 states, had legalized cannabis for medical use. And as a Los Angelino, where we have this thing called Cali sober, and it means you don't drink, but like weed, mushrooms, fine.
This was news to me that currently weed is illegal in most of the world. I was like, what? In Canada, though, in Germany, South Africa, Luxembourg, a few other countries, and in 24 of the United States, you can get it for recreational use. In Amsterdam, they have cafes where one can blaze. But it was not always so.
There have been various crackdowns and taxes, a lot of campaigns for prohibition based in really racist and xenophobic ideologies. And in 1970, cannabis was deemed a Schedule I drug. which is the highest level of restriction in this country. And it was seen as having no medicinal benefits and a high likelihood of addiction.
So it is in the same class currently, Schedule 1, as heroin, molly, and quaaludes. But in 1996, California enacted the Compassionate Use Act, and it allowed seriously ill patients to possess, grow, and use medical marijuana, if given the blessing of their doctor. And...
I know legally, according to the federal government here, it's still called marijuana, even though it seems like such a formal name and also antiquated and also rooted in racism. Pot seems like your grandma trying to have a serious talk with you. Weed also feels a little bit like, hello, hello, fellow kids. These days, I guess people call cannabis trees or they say that they garden.
I mean, also a lot of humans just communicate by emojis and in code to circumvent social media censorship. So the leaf emoji it is. But let's take a quick trip back to Massachusetts to chat with an anthropologist who literally studies the legalities and the social stigmas of cannabis for both medicinal and recreational use. And her name is Dr. Caroline Mellie.

Chapter 5: How do THC and CBD differ in their effects on the body?
And the research became more and more relevant as more states started legalizing cannabis for medical purposes. You know, each state was legalizing cannabis for different reasons. California legalized it for 11 reasons. And the last reason was, you know, if your physician thought you might be able to benefit from it. Oh, that was the last one?
Okay, so that was California's 2016 Proposition 64, and it passed with over 58% of the vote. Other reasons why it passed were decriminalization and saving money on law enforcement. Making money for kids programs. I'm making money. Making money. I'm making money.
And you might be shocked to learn that a decade later now, in a state that feeds the world, cannabis is thought to be California's biggest cash crop. And according to a February 2026 release via CA.gov, in the last eight years, California's sticky icky sales have generated more than $7.8 billion in tax revenue. But the money train, it was moving faster than the scholastic bus.
Way more research needed to happen.
And so I became really drawn to cannabis, the plant, as well as cannabinoids, the chemicals in the cannabis plant, to understand, you know, what are the effects of these chemicals? And then, you know, as legalization continued, industry started ramping up as well.
And we started to see that cannabis itself was becoming a very different type of plant than it was like in the 90s or, you know, 80s, 60s. And also products were being made that were quite different, right?

Chapter 6: What are the potential therapeutic benefits of cannabis?
People weren't just like making their own pot brownies at home. There were actually these like artisanal gourmet food products that were being prepared with cannabis infused and other products like now we have the vape pens, right? And so very little work had been done in this area.
So the genie was out of the bottle. The smoke had curled out of the bong.
The business commerce aspect was picking up and it still is picking up. People are using at much higher rates than they were before. But our science is still, you know, it's kind of in its infancy still.
I think it's interesting because I feel like if you're studying opioids, people are like, that's amazing. You must be wanting to end the opioid epidemic. If you're studying weed, people are probably like, Okay. Do you find that the opinions on cannabis are really polarized, like pro or con? Do you find that in your research or in who you present to or your study subjects at all?
It is a really polarizing topic. And I can say that some of the work that I've generated with the help of colleagues has has spurred advocacy from both groups as well as have been demonized by both groups, right? And actually, if you think about it, science should be that way, right?
So we're trying to figure out really what is the evidence, what are the effects so that we can better inform people, which is really important in this day and age.
Yeah.
Yeah.
Well, I'm wondering, because you mentioned opioids too and other addictive substances. And from what I understand, I'm not you, but from what I understand, there are receptors in our brain that say, yum, yum, yum, opioids. And there are also endocannabinoids that we create.

Chapter 7: How does the legality of cannabis vary across different regions?
Yes, I can't, I don't need to imagine it. Social interaction. I love snacks. And so they're really important in our overall homeostasis. And so, yeah, the cannabis plant has chemicals that act at those receptors.
Oh boy, this episode, it's a beast. But real quick, some botanical and cultural history, shall we? So according to the University of Sydney's article, The History of Cannabis, the plant cannabis sativa has been used by humans since at least 2800 BCE.
And Indian Hindus, Greeks, Romans, more cultures have relied on it as a remedy for, quote, a vast array of different health problems, including arthritis, depression, menstrual issues, inflammation, pain, lack of appetite, and asthma. And the word ganja, by the way, I thought that was just a catch-all, but it refers to the female flowers of the plant where most of the cannabinoids hang out.
What about all those floppy leaves? You ask, well, you can't eat them and become stony. It's not like catnip. THC needs heating, and that's called decarboxylation, to convert it from something called THCA, which doesn't do much for you, to just THC, which does a lot for you. So let's chat with Carolyn again to get more history of humans and hashish.
It passed even through the Silk Road. Both the plant itself and the expertise around it passed... from your Asia into the Middle East, India and Africa as well. So it has a really storied history as a treatment. And then there have been many surges of trying to kind of suffocate it too, right? And to ban it across time and space as well.
It's really a medicine that in, especially during its prohibition for so long, was really shaped in kind of interstitial spaces, outside legality, never through randomized controlled trials, right? I think that what comes about is a kind of folk knowledge. We might call them folk healers, right? Who have shaped cannabis medicine over time.
And so let's get back to how these things are just doing their thing. What do those receptors normally do or where do we make those cannabinoids in our body? Those come from like exercise or eating or let's say that you don't live in a place where it's legal or you just don't like getting high. How do we make those usually?
So generally speaking, we think that these endocannabinoids are usually made on demand. So for example, they are made in the cells in your brain and your body. They're synthesized in a way to be able to regulate the body's response to external or internal stimuli.
OK, so, for example, if you're in a particularly anxious situation or anxiety provoking situation, then your body might produce or synthesize those endocannabinoids. But it's really happening all the time, given how critical those endocannabinoids are to our everyday functioning.

Chapter 8: What are the effects of different cannabis strains like indica and sativa?
We don't know. It continues the molecular pathways and mechanisms through which CBD acts have not been fully established yet, but the hype is well established. And there was this Harvard Health article. It just cut to the chase with the headline, CBD products are everywhere, but do they work? Anyone's guess.
It says that when it comes to CBD products, the marketing of an enthusiasm for them has gone way ahead of the science. And It continues, there's no evidence, for example, that CBD cures cancer, as some proponents claim. There is moderate evidence that CBD can improve sleep disorders, fibromyalgia pain, muscle spasticity related to multiple sclerosis and anxiety.
And there's increasing data that CBD may help people overcome various addictions. But yeah. CBD, it's not hanging out in the same watering hole that THC is. So it's not making you high and enraptured with a screensaver or like having the best sandwich of your life, but it can potentially help out behind the scenes.
which is really interesting. CBD though, however, has many different targets, tens of different targets. And it's thought that CBD, based off of a lot of animal studies, that CBD might actually be therapeutic for a wide range of indications without... those side effects or adverse effects that come along with THC.
So you can take CBD until the cows come home, thousands of milligrams, and you will not feel intoxicated. You can take a boatload of CBD and you will not experience memory impairment. That is if the CBD has no THC in it, right? So CBD is very different than THC because people don't immediately feel the effect. And as far as we know, there's no withdrawal from the effects of CBD, right?
So it's fairly benign in that respect. We can talk about some other studies showing that there are other areas where CBD might produce adverse effects, but relative to THC, it's, you know, fairly tame, right? We do know that CBD is a therapeutic for certain indications. In 2018, it was approved by the Food and Drug Administration for certain seizure disorders.
And again, back to Caroline Mellie, who steered her research into the anthropology of cannabis and has been uncovering the racial biases and xenophobia behind certain criminalization and prohibition movements. And the policies and the blocks that researchers still face with this Schedule 1 drug. And this is also obviously spurred by and having impacts close to home for her.
And she shared more of her son's story.
We were eventually able to gain control using sort of typical pharmaceuticals, but the pharmaceuticals themselves have really catastrophic side effects. I think this is one of the really important things to understand about contemporary cannabis medicine, that it really did grow in some ways out of people's desperate circumstances.
