What will the coast Guard do about a substituted or adulterated specimen?
The act of adulterating or substituting urine specimens submitted for drug testing, is by definition, a refusal to test. The Coast Guard would initiate Suspension & Revocation proceedings against a licensed or documented mariner that adulterates or substitutes their specimen, seeking revocation of their license or document. Marine employers must report substituted or adulterated specimen incidents to the USCG if a licensed or documented mariner is involved.
