My Son Was Addicted To Heroin, We Found A Doctor

my son was addicted to heroin, we found a doctor in madison to help with his detox and therapy, but now he is addicted to the suboxone. I don't know what to do but he gets very sick even sicker from not taking the suboxone than he did when he wasn't using heroin. I think he should go to a detox center, what do you think?
