Substance abuse remains an increasing problem in the late 1990s especially among young people. This resource contains over 30 exercises designed to expand participants' understanding of the issues surrounding illegal drug use. All the exercises are photocopiable as worksheets or as overhead projections, for use with young people, and are accompanied by full instructions for use. They should be suitable for use by teachers, youth workers, probation officers, those working with offenders, and indeed any professional having responsibility for groups of young people. The workbook can also be used in conjunction with the companion volume, Understanding Drugs: a Handbook for Parents, Teachers and Other Professionals which provides a complete background reference.
