Hey there,
i also suffered from an addiction. Have you heard of Teen Challenge? (https://www.teenchallenge.org/) The program is hard, but i went through it and it completely cured me. After twelf years of substance abuse i'm really set free. I#m even a non-smoker now. I couldn't imagine that 2 years ago. I think the best idea is to go somewhere stationary. I know, you miss out some time, but it will pay out. It is way easier to stay clean, if nothing around you reminds you of your addiction. This goes also for people, that would remind you of drinking.
