Legalization of marijuana doesn't increase teen usage

In a research paper published Sept. 7 in the Journal of the American Medical Association Network Open, Sam Safford and three other authors share research that shows the use of marijuana in high school students did not increase following the passage of recreational marijuana legislation in those states.

In fact, the data shows that legalization may lead to a decrease in marijuana use by teens. 

“In the fully adjusted models, medical marijuana law adoption was associated with a 6% decrease in the odds of current marijuana use and a 7% decrease in the odds of frequent marijuana use,” the study states.

Safford, who joined MSU this semester, published the paper with D. Mark Anderson (Montana State University-Bozeman), Daniel I. Rees (Universidad Carlos III de Madrid) and Joseph J. Sabia (Center for Health Economics and Policy Studies, San Diego State University).
