Nick talks to Dr. Amir Englund, a psychopharmacologist at the Institute of Psychiatry, Psychology & Neuroscience at King's College, London. Dr. Englund's research focuses on the effects of cannabis, medical marijuana and specific cannabinoids (e.g. THC, CBD, THCV) on human cognitive function. They discuss topics including: what is the addiction liability of marijuana? What are the acute & chronic cognitive effects of THC, including how it impacts memory & executive function; how the effects of THC can be modulated by cannabinoids like CBD & THCV; the relationship between marijuana & THC and psychosis (e.g. schizophrenia); and more.

Nick talks to Christian Lüscher, MD, PhD, a neuroscientist at the University of Geneva whose lab studies the cellular mechanisms that underlie drug reinforcement, dependence and addiction. Dr. Lüscher talks about the nature of addictive drugs in the brain, how ketamine works, and the latest research from his lab look at how ketamine's unique effects within the brain's reward circuitry enable it to be psychoactive & reinforcing, but have a very low addiction liability (in rodents). He also discusses what this research may mean for the use of ketamine as a therapeutic treatment for depression in humans.
