The Drug-Free Workplace Act of 1988 (41 U.S.C. 81) is an act of the United States which requires some Federal contractors and all Federal grantees to agree that they will provide drug-free workplaces as a precondition of receiving a contract or grant from a Federal agency.
Although all covered contractors and grantees must maintain a drug-free workplace, the specific components necessary to meet the requirements of the Act vary based on whether the contractor or grantee is an individual or an organization. The requirements for organizations are more extensive, because organizations have to take comprehensive, programmatic steps to achieve a workplace free of drugs.
