A study from the University of Minnesota released this week found a correlation between raising the tobacco buying age to 21 and a decrease in youth smoking. April Wilhelm, Assistant Professor at the U of M and worked on the study.

“8th and 9th graders in Minnesota living in communities with these policies in place, they were much less likely to report use of several of the tobacco products, compared to those in communities without the tobacco 21 policies.”

Wilhelm says the numbers, collected in 2019, showed less of an impact in older teens. She says that may be because the policies are often implemented on a hyper-local level, and older kids are more mobile and able to work around rules in place.
