But there is a caveat. The determination in Clinical Psychology Review was made by a systematic review. If homeopaths want to show that homeopathy works, they simply do a review of homeopathy papers. That doesn't mean it works and so another review won't do much to assuage fears that marijuana addiction is trading one problem for another - in this case, toxic chemicals inhaled in smoke for pain relief that may not be evident.
How flawed is that sort of review? The authors also found that cannabis may help with symptoms of depression, PTSD and social anxiety. When something claims to treat a broad range of disorders which don't share much in common, it is in the land of Dr. Oz miracle cures rather than medicine.

Marijuana legalization is the latest trend for hungry government unions to keep pay raises coming so in the future it will be possible to see if anyone is being helped by marijuana or if it is just a new form of recreational drug use that has been given a health halo. The study was done in Canada and users there are hopeful legalization of marijuana could happen next year.
