Weeding Out the Grass: Brain Power!

Created by : 
National Institute on Drug Abuse

Students learn about one of the most commonly abused drugs in the United States, marijuana. A goal of this module is to use science to dispel the myth that this drug is harmless. Marijuana has a strong physical impact on the brain and body. For young people, whose brains are still developing, the effects of marijuana are even more serious. Following the lesson, the Challenge activity is a marijuana bingo game. Additional activities include a research-based presentation, a media log, the student magazine, the CD-ROM, and handouts. This is one of six modules designed for students in grades 6-9 to learn about the brain and the effects of drugs on the body.
