Like all things, moderation in everything drink, food, pills, excercise, jesus.  Yes there are positive sides it keeps most men at home in front of there computers and tv's without running the streets possibly drunk or high acting out rapes and child molestations. Alot of parents also think if there kids are gonna get high or drink they'd rather them do it at home so as not to harm or injure other folks. Hope this helps. Best wishes
