Positive and negative effects of marajuana?

+ and - Improvement of chronic pain is a positive. Negative effects include anxiety, paranoia, memory problems, disorientation, depression, sleepiness, "a-motivational syndrome"
Positive overrated. Sure marijuana might be useful for nausea in end-stage cancer, for simulating appetite and for glaucoma pain but for everything else, i believe it's overrated. More studies demonstrate major issues than positive benefits. Check out http://alvinblin.Blogspot.Com/2012/01/cannabis-use-is-it-really-safe-part-3.Html.
