we finally detoxed husband who has been on shabu for about 4 years (not heavy user, but started displaying paranoia etc recently). do we need to enrol him in an inpatient rehab facility? or can he stay clean on his own as he promised (he totally regret using it, sorry for all the pain he gave us)? he promises to visit the doctor and subject to random drug testing too. how addictive is shabu really? he used to be a great, responsible guy who is devoted to his family
