Isn it true, though, that people can only become sober through attending a 12-step group, like AA or NA?
No, but that is a common myth or misconception. No single group or method has a monopoly on sobriety. People recover through a variety of different ways. Some people benefit from attending Alcoholics Anonymous meetings. However, research and experience have shown that many others recover with the help of SOS or another support group. Some people even quit drinking or using drugs on their own, or with the support of family and friends. Still others achieve sobriety by working one-on-one with a psychotherapist. In short, different strokes for different folks!
