When states began legalizing recreational cannabis a couple decades ago, 25 million Americans said they used the drug. That number nearly tripled to 70 million by 2023.
There are a lot of open questions about how it affects us. Why do some people find more pain relief from THC than traditional painkillers? Is it really better for sleep? What are the effects of long-term use?
Host Flora Lichtman is joined by two scientists taking on these kinds of questions: Experimental psychologist Ryan Vandrey, who’s studied the health effects of cannabis for 26 years, and neuropsychologist Natasha Wade, who studies the effects of substance abuse on adolescent brains. She recently analyzed data from 11,000 teens to understand how cannabis affects development.
Guests:
Dr. Ryan Vandrey is an experimental psychologist and professor at the Johns Hopkins University Behavioral Pharmacology Research Unit and helps lead the Johns Hopkins Cannabis Science Lab.
Dr. Natasha Wade is an associate professor in the Department of Psychiatry at UC San Diego and licensed clinical neuropsychologist.
