i have NEVER heard of someone who is NOT using drugs or alcohol entering REHAB......AFTER kicking, AFTER doing outpatient, and AFTER using suboxene and then getting off of it. i'd be surprised a treatment center would admit him.............rather like going into the hospital when you are not sick just in case.........
you do seem to have a rather glorified impression of this man and wearing a cheerful set of rose colored glasses. but BEWARE, heroin addiction is not glorious and is not easy to completely overcome.
