The only thing you probably should be really worried about medically, is the high blood pressure and the strain on his heart. But, its not much worse than a lot of coffee or intense cardio. Cocaine isn't the worst drug out there, albeit, very psychologically addictive. Your friend is an adult, and has to make adult choices, this just happens to be one of them. As long as he doesn't get carried away and it begins to affect his life (ie. selling his car for more blow
), then you just have to let him run his course. But don't go calling the drug abuse hotline if he snorts a bump or two every few weeks.
