Minnesota Youth Cannabis Use Declined in 2025, New Survey Finds

Survey Data Shows Decline Following Legalization

Minnesota youth marijuana use dropped in 2025, contradicting predictions that adult-use legalization would drive adolescent consumption higher. State health officials released the data tracking consumption trends among middle and high school students in the two years since Minnesota enacted its adult-use cannabis law in May 2023.

It's the first comprehensive look at youth use patterns since legal sales began. Opponents of legalization cited youth access concerns during the 2023 legislative debate. They argued normalization of adult use would increase adolescent experimentation.

Minnesota's Adult-Use Market Context

Minnesota launched adult-use sales in August 2023, becoming the 23rd state to legalize recreational cannabis. The state's Office of Cannabis Management oversees licensing for cultivators, processors, and retailers under a regulatory framework that includes strict advertising restrictions and age-verification mandates.

Revenue from the legal market exceeded $180 million in its first full year of operation, according to state tax data. By the end of 2024, the OCM had issued 47 retail licenses statewide, concentrated in the Twin Cities metro area and Duluth.

The cleanest read on the 2025 data is that regulated markets with enforcement infrastructure don't drive youth use upward.

National Pattern Holds in Minnesota

Minnesota's youth-use decline aligns with data from Colorado, Washington, and other early-legalizing states, where adolescent consumption remained flat or fell post-legalization. A 2024 CDC analysis found no statistically significant increase in youth cannabis use in states with legal adult markets compared to prohibition states.

Researchers point to several factors. Regulated retailers face steep penalties for selling to minors, reducing access compared to unregulated dealers. Public health campaigns funded by cannabis tax revenue target youth prevention. Legal markets also reduce the social normalization effect of black-market transactions in schools and neighborhoods.

What Happens Next

The Minnesota Department of Health plans annual youth-use surveys through 2030 to track long-term trends. State legislators allocated $12 million in cannabis tax revenue to prevention programs in the 2025 budget cycle—funding school-based education and community outreach in counties with high adolescent use rates.

The next data release is scheduled for May 2027. Advocates will watch whether the decline holds as the retail market matures and product availability expands beyond the initial rollout phase.
