Theres alot of new research being done about cannabis in relation to mental perception (I tend to think of mental illness differantly than most conventional thoughts) and for the most part its all positive. Talk to any psychiatrist and ask them if you should stop smoking weed. I guarentee you they will either not say anything or they will tell you ,you should keep doing it. Man if it helps do it! My mother and brother both are depressed and I know what thats like to go through.
