Study: Adult-Use Cannabis Regulations Associated with Self-Reported Declines in Youth Use
The enactment of laws regulating the use of cannabis by adults is associated with short-term declines in self-reported cannabis use by young people, according to findings published today in the journal JAMA Pediatrics.
“Ensuring the safety of our kids is always a top priority,” said NORML State Policies Coordinator Carly Wolf. “And the best way to do that is to regulate cannabis, bring products behind a counter, and phase out the illicit market.”
A team of researchers from Montana State University, the University of Oregon, the University of Colorado, and San Diego State University assessed teen cannabis use rates, as reported by the Youth Risk Behavior Survey, in states that had legalized either the medical or the recreational use of cannabis.
After adjusting for individual- and state-level covariates, authors reported that states with “recreational cannabis laws were associated with an eight percent decrease in the odds of cannabis use and a nine percent decrease in the odds of frequent cannabis use.” By contrast, states with medical cannabis laws only were not associated with any statistical changes in youth use.
They concluded: “Consistent with the results of previous researchers, there was no evidence that the legalization of medical cannabis encourages cannabis use among youth. Moreover, the estimates reported … showed that cannabis use among youth may actually decline after legalization for recreational purposes. This latter result is consistent … with the argument that it is more difficult for teenagers to obtain cannabis as drug dealers are replaced by licensed dispensaries that require proof of age.”
An abstract of the study, “Association of cannabis laws with teen cannabis use,” appears online here. Additional information is available from the NORML fact-sheet, “Cannabis Regulation and Teen Use Rates,” here.

NORML’s mission is to move public opinion sufficiently to legalize the responsible use of cannabis by adults, and to serve as an advocate for consumers to assure they have access to high-quality cannabis that is safe, convenient, and affordable.
