This directory is intended as a resource for persons requiring knowledge about speaker's bureaus concerned with drug abuse prevention throughout the country. Information is derived from the National Clearinghouse for Drug Abuse Information National Inventory of Drug Abuse Programs, part of a comprehensive computerized information-retrieval system covering the field of drug abuse. The guide reflects only those drug abuse programs which have been brought to the attention of the Clearinghouse and which have reported an active speaker's bureau. No attempt at evaluation or assessment of program effectiveness or the speaker's bureau is made. Identifying data include program name, address, telephone number, and director's name. Three hundred sixty-four programs in 48 states (excluding New Mexico and Oklahoma), District of Columbia, and the Canal Zone are listed. (BL)
