This article summarizes the theoretical underpinnings, substantive con
tents and limitations of comprehensive social-influences-based drug ab
use prevention programming. This type of programming has produced the
most consistently successful preventive effects. There is some evidenc
e that one major parr of these programs changing social norms, is an e
ssential ingredient for successful drug abuse prevention programming.
Research suggests that these effects may not be contingent on the use
of refusal assertion training, a prototype activity of social-influenc
es-based prevention programs. Because programs when disseminated to th
e public, often contain only a subset of lessons from the social influ
ences curriculum there remains the potential error of implementing a c
ombination of lessons that may not be effective. Further there is evid
ence that other types of prevention programming such as physical conse
quences programming, may be successful in some situations Finally soci
al-influences-based programming may not be as effective with some subp
opulations such as high-risk youths.
