Framing the issues

The use of psychoactive substances is commonplace in many parts of the world, despite the efforts of policymakers, government officials, public health advocates, and concerned citizens to prevent, eliminate, or control it. If previous experience can serve as a guide, in the future many countries will face periodic drug-use epidemics, followed by aggressive policy responses to suppress them. Continued endemic drug use generates a patchwork of policy responses that never quite keep up with the problem. The scientific evidence on the impact of policy constitutes the core interest of this book and consists of three broad approaches: programmes to prevent drug use, treatment and harm-minimization services that help heavy drug users change their behaviour, and supply control programmes to restrict access to illicit substances. This book suggests that public health concepts provide an important vehicle to coordinate supply control and demand reduction.
