TRANSCRIPT
ASHLEY GLODE: Hello, and welcome to ASCO Education's podcast on medical cannabis, also referred to as medical marijuana. My name is Ashley Glode, and I am an associate professor with the University of Colorado School of Pharmacy.
It's my pleasure to introduce our three guest speakers Dr. Ilana Braun is chief of the division of adult psychosocial oncology at Dana-Farber Cancer Institute, and an assistant professor of psychiatry at Harvard Medical School. Dr. Daniel Bowles is an associate professor of Medical Oncology at the University of Colorado. We're also joined by Dr. Kent Hutchison, a professor of psychology and neuroscience at the University of Colorado Institute of Cognitive Science.
Let's start with a simple but fundamental question. What is medical cannabis or medical marijuana?
ILANA BRAUN: So Ashley, I think that's such a great first question. I think of medicinal cannabis as herbal nonpharmaceutical cannabis products that patients use for medicinal purposes. And typically they're recommended by a physician in compliance with state law.
DANIEL BOWLES: Dr. Braun makes a really good point. And I think it's important to know when patients are referring to medical cannabis, there's a wide variety of different things they could be referring to. Sometimes they would be referring to smoked herbal products, but there are also edibles, tinctures, ointments, creams, all sorts of herbal-based products that people use and call medical cannabis.
And then there are also the components that make up medical cannabis-- largely, the cannabinoids. And I think the big ones people think about are THC and CBD. And sometimes those are used in their own special way. So I think that it's important for us as providers to be able to ask our patients, what is it that you mean when you say, I'm using medical cannabis?
ILANA BRAUN: I think that's such a great point. And I will add I think it's also important to remember that when you offer a medicinal cannabis card to a patient, you're giving them license in most states to access any number of products. It's not an insurmountable challenge, but it's a whole new world for traditional prescribers who are used to writing a prescription and defining what is the active ingredient, how often a patient will take the medicine, by what means.
DANIEL BOWLES: I think the other thing we need to be very aware of, as hopefully people are listening to this across the country and elsewhere, is the laws vary wildly from jurisdiction to jurisdiction about what consists of medical cannabis, who is allowed to use it, and in what quantities. So I think it's really important that as we learn about these and we think about these, we think about how they apply to any of our specific situations in which we live in practice.
KENT HUTCHISON: So it's interesting-- just follow up on what Dr. Braun and Dr. Bowles, what they're saying, those two words-- right-- medical and cannabis. I think the medical part is somewhat easier because it can refer to the reason the person is using. Are they using for medical reasons are they using for recreational reasons, even though that's a blur?
But the cannabis part I think is what's really complicated. And this is what Dan was getting at. All the different products, all the different cannabinoids, I mean all the different bioactive terpenes and everything else in the material, all different forms of administration. That is where it gets super complicated to really define what that is. And then of course, there's so little research w
