Well, I start out with I've been smoking for 10+ years and am no where near bi-polar or any other medical condition. I have a short temper and am moody, but I was born that way.

On the flipside, my brother has something going on, not quite sure what it is or what meds the doctors have him on. But basically, before he left for college, everything was fine. While there, he started smoking. Now, he went to college in Kansas and we were in New Jersey; according to him, all he smoked was weed. But he came back one semester and was wierd. I mean, he would just start talking out of nowhere or laugh to himself for no reason. Ended up he tried to kill himself and that's when my mother started aggresively seeking help for him. It's been years and he's on meds, but he's almost back to 'normal'. But the question remains was it the weed that brought it on, did he get hold of bad shit, or was it some other factor.
