SAPlist is the #1 online directory for Substance Abuse Professionals (SAPs)

If a DOT employee has a positive test result, a refusal to submit to testing, or a violation that doesn’t involve a test, they must complete a SAP return-to-duty process before returning to DOT safety-sensitive functions.

SAPlist will help you find qualified SAPs so you can set up a face-to-face assessment.
