Self-reported use of marijuana by high-school students is significantly lower today than it was 15 years ago, according to an analysis of CDC data published in the journal Drug and Alcohol Dependence. “People have been very quick to say that marijuana use is going up and up and up in this country, particularly now that marijuana has become more normalized,” study leader Renee M. Johnson, PhD, MPH, an assistant professor in the Department of Mental Health at the Bloomberg School said in a press release. “What we are seeing is that … the rates of marijuana use have actually fallen.”
Current use of marijuana by those between the ages of 12 to 17 has remained largely unchanged over the past decade, while young people’s self-reported consumption of alcohol and cigarettes has fallen to record lows, according to federal data compiled by the Substance Abuse and Mental Health Services Administration.

Authors reported, “Our results are not consistent with the hypothesis that the legalization of medical marijuana caused an increase in the use of marijuana among high school students. In fact, estimates from our preferred specification are small, consistently negative, and are never statistically distinguishable from zero.”
Adolescent consumption of alcohol and tobacco fell to historic lows while self-reported annual use of cannabis held steady, according to survey data released Wednesday by the University of Michigan at Ann Arbor — which has been sampling teens consumption of various licit and illicit substances since the mid-1970s. But you wouldn’t know these facts if you read today’s mainstream media headlines.
