Based on social research conducted in different countries in Europe, the U.S. and Australia, this anthology is the first to provide detailed insights into small-scale drug distribution. A main focus is the phenomenon of ‘social supply’, i.e. buying illicit drugs from friends, which covers a substantial part of the retail market. For cannabis users, cultivating their own plants is another important source. This volume deals with different social aspects of these non-profit-oriented forms of drug distribution, as well as profit-oriented small-scale dealing. While the illicit drug trade is commonly referred to as a world dominated by ruthless criminals, this book draws a different picture.
