To assess and analyze existing business practices concerning drug use by employees and related employer relationships with manpower and drug addiction control agencies, a survey was taken of the practices of both employers and drug treatment programs with respect to the employment needs of drug users and exusers. To obtain results, questionnaires were administered to employees, drug program personnel, and drug users. Findings include: (1) Drug programs do not see vocational training or job placement as playing an important role in the rehabilitative process, and (2) Employers are actively excluding people with a history of drug problems from the labor forces. Supplementing the survey and questionnaire data is a comprehensive review of the relevant literature and an accompanying bibliography. (Author/SN)
