Now, I don’t want to somehow talk about the dangers of alcohol or to besmirch the reputation of alcohol, because I think that every society should have intoxicants. We need intoxicants. And every society has always had intoxicants. So alcohol is fine...(intoxicants) make people more interesting, decreases anxiety. Alcohol is associated with a wide range of health-beneficial effects—decreased heart disease, decreased strokes, all of these sorts of things. The same can be true of a drug like marijuana—helps people sleep better, can decrease anxiety at the right doses."
