Advocates and lawmakers on both sides of the Tobacco 21 issue are now dissecting the findings of a University of Minnesota study released this week showing a positive correlation between raising the tobacco age and a decline in youth smoking. Researcher and family medicine doctor April Wilhelm said this is just a starting point to better understand the trends surrounding Tobacco 21 policies.

“And it is just really important they are having the effect that we’d like, which is to reduce the adolescent use of tobacco products.”

Wilhelm says the next step for researchers is to find out how policies are being implemented in different ways and what impact those differences have on youth smoking.
