While lawmakers and politicians have been coming out in droves to endorse the legalization of medical and even recreational marijuana, the medical establishment hasn’t been as supportive. But the tide could be turning: The American Journal of Public Health has just published a study suggesting that states that legalize medical marijuana can expect a reduction in suicide rates.

A team of economists looked at state-by-state statistics on suicide rates over a 17-year period, from 1990 to 2007, comparing data from states that voted to legalize medical marijuana with those that kept it criminalized. According to their calculations, in the three years following legalization, the suicide rate dropped, on average, 10.8 percent among men in their 20s and 9.8 percent for men in their 30s.

“The negative relationship between legalization and suicides among young men is consistent with the hypothesis that marijuana can be used to cope with stressful life events,” wrote the authors.
