I always find these studies amusing! You can do anything in MODERATION and be productive. They base their studies on someone that smokes an ounce a day or drinks a quart a day. Of course their going to be fucked up! Didn't see any mention of coffee or donuts though! What happens to the human psychy and productivity if you weigh 500#s from your ass to the floor? Use and abuse shouldn't be put into a general catagory! :thumbsup:
