Crystal Meth Anonymous
Crystal Meth Anonymous was also born out of AA. After witnessing an upsurge of crystal meth addicts joining AA to get sober, one former addict began this offshoot in 1994. He figured meth addicts could benefit from a 12-step model, but they needed their own tailored version of support. Turns out, that hunch was right, as today you can find over 600 CMA meetings worldwide.
