Teens who Use Marijuana: High School Students

State: California
Measurement Period: 2019
This indicator shows the percentage of high school students who used marijuana one or more times during the 30 days prior to the survey.

Why is this important?

Among youth, illicit drug use is associated with heavy alcohol use, tobacco use, delinquency, violence, and suicide. Marijuana is the most commonly abused illicit drug in the United States. Marijuana intoxication can cause distorted perceptions, impaired coordination, difficulty thinking and problem solving, and problems with learning and memory. Many research studies have shown that marijuana's adverse effects on learning and memory can last for days or weeks after the acute effects of the drug have worn off. Chronic marijuana use can lead to addiction. Addictive behaviors may result in harmful effects on social functioning in the context of family, school, work, and recreational activities.
