Small but significant decreases in adolescent abuse of tobacco, alcohol, an
d marijuana in recent national surveys allow clinicians to feel some optimi
sm about defeating the specter of substance abuse. It appears that changing
the perception of risk and increasing adolescent disapproval of substance
abuse are key goals. For every adolescent, reducing risk factors while iden
tifying and enhancing protective factors optimizes an individual's opportun
ity to avoid potentially harmful behaviors. While focusing energy and commi
tment on each adolescent, however, clinicians cannot ignore the need for wi
der social change because the proximal adolescent domains of individual, fa
mily and school factors are interrelated and embedded in the community and
societal contexts. Every sector in society plays a crucial role in preventi
ng adolescents from experimenting with and continuing to abuse tobacco, alc
ohol, or illicit drugs, from parents, physicians, educators, and policy mak
ers to every adult invested in the health and well-being of adolescents.
