FF - much good advice has already been posted above so I don't have much else to offer except a couple of things... This situation is waaaay beyond your capability. Everything you have described can only be helped by sound, professional help from experienced personnel at an inpatient facility. No disrespect but Carmela is exactly right - your friend WILL eventually rob you & your family and do ANYTHING to buy that fix he craves. I have seen and heard stories like this that seem to have the addicted person floating from place to place and friend to family member preying on their good nature and empathy. Those people only end up with heart break, guilt and an empty wallet until the addict finds another person to help him out. God bless and good luck.
