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.”
Changes in marijuana laws are not associated with increased use of the substance by teens, according to data compiled by Washington’ Healthy Youth Survey and published by the Washington State Institute of Public Policy.
The enactment of state laws legalizing the use and distribution of cannabis for medical purposes has not caused an increase in marijuana use by adolescents, according to the results of a federally funded study published this week in Lancet Psychiatry. Investigators concluded, “[T]he results of this study showed no evidence for an increase in adolescent marijuana use after the passage of state laws permitting use of marijuana for medical purposes. … [C]oncerns that increased marijuana use is an unintended effect of state marijuana laws seems unfounded.”
Another study has once again affirmed that the enactment of statewide medical cannabis laws is not associated with increased rates of adolescent marijuana consumption. According to data published this week in the American Journal of Public Health, the passage of medical marijuana laws in various states has had no “statistically significant … effect on the prevalence of either lifetime or 30-day marijuana use” by adolescents residing in those states.
