A friend of mine is a drug addict. addicted to hydrocodone, oxy's and roxy's. He will not admit the latter 2. Has lost a lot of weight. Has become irrational at times. Does not think clearly a lot. Most importantly , lately he is "crashing". Unable to function at all. What can I do for him. I am watching him die and he will not listen to reason. Even though he has to know the addiction is what is causing his body to shut down. Any help is appreciated
