The "British System" is known world-wide as a highly effective means of managing heroin addiction. Drs. Strang and Gossop have for many years been actively involved in research into clinical practice. In this book, they present an overview of British drug policy set in the context of international activities, with contributions from key figures in the field, covering both historical and contemporary aspects of the evolving "British System." Several contributors give previously unrecorded accounts of events during critical phases in the evolution of the UK response to illicit drug use, while others outline the critical issues within today's policy reviews.
