" The other, more uplifting, explanation is that the meetings offer social support. Like everyone else, alcoholics and drug addicts are capable of remarkable feats of self-control in order to gain social acceptance. In fact, that desire for peer approval is often what got them in trouble initially. Most people don’t enjoy their first taste of alcohol or tobacco. Most people are scared to put unfamiliar drugs into their bodies. It takes real self-discipline to inject yourself with heroin the first time. Teenagers will disregard everything—their own fears, their parents’ warnings, physical pain, the possibility of going to jail or dying—because they’re convinced that social acceptance requires them not only to take risks but to do so in a cool, seemingly unconcerned manner. They exert self-control to overcome their inhibitions and more self-control to hide their negative feelings. "
