I think it's silly to try to subscribe to a set of rules that just aims to get rid of all the bad stuff. It makes more sense to me to simply balance the consumption of these "drugs" (narcotics, alcohol, food, games, children, sports, etc). In fact, don't even call them "drugs"; call them "desire satisfiers". Satisfying any given desire has a cost and a benefit, and we all exist in this huge, messy web of conflicting desires that have varying and dynamic costs/benefits. The challenge of living is trying to balance the satisfaction of all our various desires.
