In this video we cover what marijuana is and the effects it has on teenagers. We dive into the long-term cognitive effects for teens, whether they are different for teens vs adults as well as limitations and barriers to research.

This video was made by McMaster Demystifying Medicine students Gurratan Gill, Jiawei Sun, Jiawen (Fred) Deng and Simran Saini.
