Researchers from Montana State University, San Diego State University, and the University of Colorado-Denver are saying marijuana usage may have a direct effect on lowering suicide rates for men from 20-39 years old.
From 1990 to 2007 researches analyzed 12 different states that had legalized medical marijuana at the time. During the study, data showed that suicide rates were nearly 11 percent lower where marijuana usage was medically legalized compared to states where the drug was not.
The authors of the study say the relationship between marijuana legalization and suicides among young men are consistent with the idea of marijuana being used to cope with stressful life events. However, alcohol consumption was considered a factor as well.
Besides Washington and Colorado legalization, 18 other states permit medical marijuana usage.
