The late 1980s marked the beginning of a sea change in research and in
tervention on tobacco use by young people, when the first studies were
published demonstrating the ease with which adolescents could purchas
e cigarettes. Since then concern with the commercial availability of t
obacco products to youth has grown, becoming deeply entrenched in both
research and policy efforts. This paper reviews the history of restri
ctions on youth access to tobacco, the evidence that commercial source
s of tobacco are available and important to adolescents, and the ratio
nale for various components of policies to restrict access. We also re
view the recent expansion of policies addressing youth access to tobac
co at all levels of government, the tobacco industry response to this
expansion, and issues that have arisen as this expansion has developed
.
