I think it can be part of a useful recovery program, but is not in and of itself enough to promote recovery. For example, don't let your self get involved in the "If only, I can fix or come to terms with X, then I'll be able to stop..." trap. That's a recipe for continued use.
You need a plan and support for stopping, and strategies to deal with cravings too.
