Cocaine, AIDS and i.v. drug use.

The papers in this volume cover a wide range of important topics. Yet many other equally important topics are not addressed. These include: (1) emerging trends in the epidemiology of HIV and drug use, such as the evidence that crack use may lead many of its practitioners to engage in high risk sex; (2) ways to deliver HIV prophylaxis to infected drug injectors, sexual partners, or perinatally infected children; and (3) the effectiveness of standard outreach in encouraging risk reduction. They do, however, provide important information about how to deal with both cocaine use and AIDS. They also raise many fruitful issues for additional research.
