If his own mother who is a social worker has established her boundaries and refuses to deal with him, then he is definitely in trouble...
If he says he is in recovery but is suspected of abusing his Valiums and you or someone knows or can verify it because he comes up short every month on his pill count, etc..., someone (don't know who) should confront him and tell him he's full of crap and in relapse (does he have a sponsor or any 12 step friends?)......sorry but i have prior experience with all of this and coddling and telling people in recovery what they want to hear rather than what they need to hear is a form of enabling.......and using under the guise of 'it's a dr.'s prescription' is a line that is an old rationalization used by addicts for ions...
I took care of a patient years ago who was 32 years old when I came to care for him with severe type 1 diabetes, he was partially blind and had severe neuropathy when I first took care of him....basically acted like your fellow, except in a nicer manner, thank God...but myself, the agency, his mom, etc couldn't force him to do anything....well by the time he died at age 35 he had a heart attack, was on peritoneal dialysis, lost both legs, (in that order) and basically died in what i would term "suicide by noncompliance".....it was a shame too because he really was a sweetheart....he just couldn't get past all his losses, dwelt on them, and no matter what interventions were attempted continued to be non compliant....i guess his attitude was i'm going to do what i want to do and enjoy what i can, but unfortunately it was at his own detriment......i always have to wonder how much longer or better things could have been had he been compliant....but i'll never know...to quote frank sinatra, he did it his way.....
sad, but bottom line...it was his right....

i hope someone can get through and intervene with your patient before it is too late.....
you know that tv show "Intervention" on A&E? well the disabled are not exempt from that...maybe a group of family/friends/caregivers/people he may know in recovery could stage one....don't know if an addictions counselor is available but it could be a starting point....addicts need to be confronted.....
hope this helps, and tell him someone is praying for him
