Nightsd- Nar anon and Al anon provide support for the friends/family of substance abusers. Often the friends/family are enablers although perhaps not in every case. For me, codependency means allowing one's mental/physical/emotional state to be a function of an addicts' mental/physical/emotional state. Because such codependency can be destabilizing, friends/family often need to detach from their addicted loved ones and create personal boundaries to maintain some peace/sanity in their lives.
