you did not say who this is but it does not really matter. what matters is he has some one he can control & make them help keep him high. him being high is not going to help with the cure. he needs medical treatment & not drugs. i bet if you quit he would get it. it is not your responsiblily to help him. you say u are tired of it but u keep doing it. i hope he gets the help he really needs.prayers going up for him & you. i know it is hard to see someone we love suffer as he is.
