As the studies reported throughout this volume make abundantly clear, the college environment is flooded with alcohol and drugs and a student who wishes to abstain must swim against the tide. For no students is it more important to abstain than for those already in recovery from substance abuse and addiction. Although other factors, such as social identity and social support (see Chapter 7 by H.H. Cleveland et al., this volume), are certainly important to the recovering adolescent, a strong sense of personal identity can help a student resist the pressures, both internal and external, to use substances because ultimately only the addict himself or herself can choose to follow a path out of active addiction.
