You all are biased. All of us know someone who should quit smoking pot, because it can become a problem and denying that it is a problem, if not for you then someone else, only keeps us ignorant. Now I would like to see an article that tells the truth, once in awhile. Marijuana contributes very little to mental dis-ease. Ultimately, the responsibility lies in the user to come back to reality. But just don't sit back and watch. You know someone, give them a little tough love. It'll shape 'em up.
