Medicine Grand Rounds - C. Everett Koop Lecture: Marijuana: A Prescription for Trouble?

Dr. Gunderson follows the growth of the marijuana industry from 2001 when medical marijuana cards were first issued in Colorado, to full legalization for recreational and medical use in 2012. She highlights the exponential growth of an industry that has potentially negative physiologic consequences as well as adverse impacts on communities in Colorado. Analysis of today’s marijuana plants and marijuana derived products show significantly higher THC potency from plants that were grown in the 1970s. She cautions that cannabis is neurotoxic to the adolescent brain, can accelerate the onset of psychosis in teenagers and has the potential to prime the brain for addiction.
