maybe you should tell his parents.maybe they can get him into a rehab. i do not know.i know this friend of your is on the way to self destruction if he does not want any help to get off of them. you are right,so many, many people in the u.s.a. are on one drug or another. there is nothing we can do about it.all we can do is learn to take care of ourselves. my son is the addict in my life. if you could make them quit using,he would not be clean today.he does not want to quit so there is noway i can make him.it is a terrible feeling to see the ones you love or care about self destruct themselves. keep coming back. i will say a prayer for your friend & for you too.
