In early February, the U.S. Coast Guard issued a Marine Safety Advisory regarding the use of hemp plant products. The advisory was issued to ensure that mariners, employers and associated organizations were aware of certain product ingredients. A number of items marketed as hemp or cannabidiol (CBD) may contain enough tetrahydrocannabinol (THC) to cause a positive drug test.
In accordance with 46 CFR 16.201(c), an individual who fails a chemical test for dangerous drugs must be removed from duties directly affecting the safe operation of the vessel. The person is also subject to suspension and revocation proceedings against his or her credential under 46 CFR part 5.
