My experience is that many of the negative side effects of recreational drugs come from the culture in which they are taken, and the habits associated with them. Taking ecstacy, for example, often involves staying up all night and dancing. I also feel terrible if I deprive myself of sleep without taking drugs, but I tend not to do that so often. So are the drugs dangerous, or are we just failing to construct heathy social norms around them?
