After reading that FF I've tried to help friend(s) in the past but if hes that heavy into that shit I'd drop him off at the nuthouse if he doesn't have insurance a local social worker can fill out welfare stuff unless his parents are well off and can help I don't know what else you can do to really help him. Before you know it his bike and your car will be on craiglists for $100.00 all joking a side if he gets sick and starts throwing up all over the place your really in for it get him the fuck outta there!
