USCG Merchant Marines

DOT Drug Test for Merchant Marines or US Coast Guard | Health Street

The US Coast Guard is meticulous when it comes to their drug testing requirements. If you are applying for a Merchant Mariner's license, Captain's License, or some other duty covered by USCG regulations, then you need to get a USCG Merchant Marines Drug Test. However, it's not just any test, and you can't just go to any clinic or lab.
