In this episode, I discuss cannabis (aka marijuana), including the biological mechanisms underlying its effects on the mind and body, its known medical applications, its impact on libido, creativity, hunger, hormones and more. I also cover the known adverse health consequences of chronic and even acute (one-time) use and the factors that determine if cannabis is helpful or harmful. Additionally, I detail how the various strains of cannabis: sativa, indica and hybrid strains, can produce such divergent effects depending on the strain type, THC-to-CBD ratio, total dosage, and frequency of use. I review why cannabis can impact speech patterns and one’s propensity to develop anxiety/depression during and after use and, in some individuals, paranoia. As the legal landscape for cannabis is rapidly evolving, this episode should interest a wide audience, including former/current cannabis users, those in the medical, sports, law enforcement, and educational communities and, of course, children, teenagers, and parents.

My guest is Casey Halpern, M.D., Chief of Stereotactic and Functional Neurosurgery and Professor of Neurosurgery at the Perelman School of Medicine at the University of Pennsylvania. Dr. Halpern’s research and clinical practice focus on using deep brain stimulation to treat compulsive and movement disorders (e.g., binge eating disorders, bulimia, obsessive-compulsive disorder (OCD) and Parkinson’s disease essential tremor, dystonia). We discuss using deep brain stimulation to help patients who suffer from movement and compulsive disorders and applying this treatment to patients afflicted with binge eating. We also explore applications of this technology to other conditions such as OCD, anorexia and tremor, and the future therapeutic directions of the use of non-invasive brain stimulation approaches, including transcranial magnetic stimulation and ultrasound, for the treatment of other psychiatric illnesses and conditions. This episode will interest those curious about the biology of eating, anorexia, bulimia, compulsive thoughts and behaviors, and movement. For the full show notes, visit hubermanlab.com.

In this episode, I explain how nicotine impacts the brain and body, including its potent ability to enhance attention, focus, and alertness, increase blood pressure and metabolism and reduce appetite. I discuss nicotine’s ability to increase the action of neurochemicals, including dopamine, norepinephrine, and acetylcholine and activate sympathetic (alertness-promoting) neural circuits. I also discuss common nicotine delivery methods, such as cigarettes, vaping, dip, and snuff, and how they each create their own unique experience and how they, but not nicotine itself, cause cancer and other adverse health effects. I also explain science-based tools to permanently quit smoking cigarettes or vaping, including peer-reviewed clinical hypnosis tools, antidepressants, and alternative nicotine replacement (patches, lozenges, gums etc.). As nicotine is one of the most widely used substances with billions of users — most of whom report wanting to quit — this episode ought to be of interest to former/current nicotine users, those who want to quit smoking or vaping and/or those interested in learning the biology behind how nicotine impacts the brain and body.
