NA isn't just for smack slammers and crack heads. Check it out? I was a 40-year pot head and couldn't have gotten clean without peer help.
And on the sober thingy, smoking pot or taking Xanax without a prescription isn't the definition of the term in my book. I tried the eliminating one drug at a time thing. Didn't work out real well.
If you think you have a problem you probably do. And there is no barometer to how many pills you take to qualify for NA. I do NA and AA and have never seen someone laughed at for having a desire to get off their poison of choice.
