What are the chances that a 43-year-old crystal meth addict will get clean?

well it would be pretty hard to do depending on how long he or she has been doing it . for me its been hard 15 years , my body needs it to be normal and i cant do much if i don't have it. its been burned into my system for years and i can think ,do things better and have energy. some people wont agree with this but every body's different. the person could get clean, but i know rehab don't work, you have to want to quite in your own mind , don't associate with any of your old friends or connections , move away from were u lived previously to using. but the thought will always be there and its easy to relapse when things go wrong.
