DEPRESSION & Cannabis studies completed

Depression is a tough thing. There are more than 350 million people worldwide that suffer from depression. One of the saddest things to me about depression is the lack of effective medications that a person can take. Doctors almost always prescribe pharmaceuticals for depression, many of which have harmful side effects. Whenever you see a commercial on TV for a depression medication, the list of potential side effects is usually longer than the segment of the commercial dedicated to how well it works. I have seen many pharmaceutical commercials list ‘thoughts of suicide’ as one of the main potential side effects.

A study was recently released which found that marijuana can be an effective treatment for depression. Marijuana of course doesn’t cause the side effects that pharmaceuticals do. Per the Huffington Post:
