What is the endocannabinoid system? Did you have that friend in high school with the hemp shirt who told you, "The body was designed to smoke pot, man!" That is not as crazy as it sounds. Trevor and Kirk talk to Dr. Robert Laprairie. He is a pharmacologist who studies the endocannabinoid system. Your body produces its own cannabinoids and has receptors that can accept external cannabinoids like THC and CBD. But just because cannabis is natural doesn't mean it shouldn't be used with caution. Dr. Laprairie also discusses interactions with prescription medications and other thing to watch for. But in general Dr. Laprairie is very positive about cannabis research in a post-legalization Canada!
