Hi guys, I found a couple of scientific studies on depression and cannabis that might interest you. The first is pretty high tech "Cannabinoids promote embryonic and adult hippocampus neurogenesis and produce anxiolytic- and antidepressant-like effects" http://www.jci.org/cgi/content/abstract/JCI25509v1 This is about a synthetic cannabinoid. This next one is way more readable- "Decreased depression in marijuana users" http://marijuana.researchtoday.net/archive/3/3/268.htm . If you want to research it further, just do a search on --cannabis abstract depression--and you'll get all the latest studies.
