This technical assistance paper is designed to give trainers guidance on teaching the development and use of substance-abuse lessons found in "Street Law: A Course in Practical Law." The paper provides background on the lessons, a rationale for using the lessons, and sample agendas to use in training. "Street Law" contains substance abuse lessons in the areas of criminal law, juvenile justice, torts, family law, housing law, and individual rights and responsibilities. The substance abuse prevention lessons are designed to encourage young people to examine the consequences of substance abuse from the perspective of both individuals (victims, legislators, judges and law-enforcement personnel) and society as a whole. An index of alcohol, drug, and tobacco related materials found in"Street Law" and an evaluation form to be used in conjunction with "Street Law" materials can be found in the appendix. (TSV)
