29 CFR Part 1630, Regulations to Implement the Equal Employment Provisions of the ADA (Title I Regulations with amendments issued through May 2016)

(1) General policy. For purposes of this part, a test to determine the illegal use of drugs is not considered a medical examination. Thus, the administration of such drug tests by a covered entity to its job applicants or employees is not a violation of §1630.13 of this part. However, this part does not encourage, prohibit, or authorize a covered entity to conduct drug tests of job applicants or employees to determine the illegal use of drugs or to make employment decisions based on such test results.
