My daughter's ex-bf's parents send him to Canada to get this treatment.. and imo I don't think it has helped him at all. He is a deceitful manipulative and abusive user that even though he is no longer on heroine.. he is still using MJ, and ordering phenazepam from the internet and shooting that up., and doing acid and pulling the wool over his parents eyes..It is not a 1 time treatment. He used to go every 3 months, then got warrants for not showing up to work detail and stopped going..
