Have you talked to an addiction counselor about your plan? Are there any kids in your home? Is he currently participating in NA or attending therapy? My stepdaughter is a heroin addict, and moving back to her mom's house did not help her. She ended up leaving needles and heroin around the house, and stole from the family.
You aren't wrong for wanting your son to beat heroin addiction. It is good for you to educate yourself about his addiction, and find support for yourself. You didn't cause you son's addiction, you can't cure it, and you can't change him.
