Study finds little evidence supporting medical marijuana for treatment of depression

A new study finds little to no evidence that marijuana is an effective treatment for anxiety, migraines, depression and post-traumatic stress disorder, azcentral.com reported.

University of Arizona researchers, working on behalf of the state Department of Health Services, conducted a review of dozens of studies that looked at marijuana use in relation to the four medical conditions and found most of the research did not adequately show medicinal risks versus benefits of marijuana.

According to azcentral.com, both state health officials and medical marijuana advocates agree the lack of scientific evidence is mainly due to the research restrictions on controlled substances.

The study could negatively impact efforts by advocates to expand Arizona’s medical marijuana program to include treatment of anxiety, migraines, depression and PTSD.  While state officials have heard anecdotal evidence that marijuana can help the conditions, they say they will only base their decision on scientific evidence.
