Preventing relapse into substance use means first helping the teenager
to develop a state of recovery. This involves completing a First Step
of a 12-Step program, whereby the teenager accepts that drugs and alc
ohol have been destructive in his or her life and that moderate use is
impossible. Thus, abstinence is necessary in a productive life. Paren
tal support is also established. The two more common causes of relapse
are being in the presence of alcohol- and drug-using peers and the pr
esence of co-existing psychiatric problems.
