Personally I think it would, since he is basically self medicating with alcohol, replacing it with mmj. If he isn't a alchy, he should know, or be told that the alcohol is only hurting him, might numb the senses in the short term, but in the long term it will be eating away at his liver, and mmj would be safer, and add functionality to the person while medicated.

and while I'm making an appearance in the thread might as well ask, any suggestions on strains for depression/anxiety. Don't currently live in a mmj state, but still would be good to know..
