Ok. Not going to debate this with you. I WAS around AA AND NA long enough to know. Over 2 years total.
How about those "spiritual, not religious" meetings that end with the LORD's PRAYER? I believe there is NO "higher power, spirit, god, godess or doorknob that will help me to not do drugs." I view this as silly, along with the 1st step, second step, third step and 6th and 7th step. Any step that mentions "god" says something about that power doing something for you. Taking away character defects, relieve our obsessions, etc.
I choose to empower MYSELF, rather than "leaving it up to god." Look up ,the origins of AA (which is where NA comes from). Christians trying to preach and convert... The Oxford Group.
NA is great for those who believe in religion of a god, but for others who cannot lie to themselves, it is counterproductive.
BTW: Outpatient rehab is a good first step, as well. That and NA are good for developing friendships with people trying to stay clean. That, in my view, is the best thing about the program.
