Study: Alcohol causes more problems than marijuana for high school students

Teen marijuana users report fewer drug-induced problems than teen alcohol users, according to a new study published in the American Journal of Drug and Alcohol Abuse.

New York University researchers looked at high-school student surveys and found that alcohol, compared to marijuana, reportedly led to more unsafe driving, brought greater harm on relationships with friends and significant others, and caused more regrettable behavior. Marijuana, on the other hand, more often led to problems with authority figures, such as teachers, supervisors, and police; less energy; and less interest in other activities.
