Marinol?

[QUOTE=Hobb C. Peatfingers;152418]Does anyone know what the USCG stance is on a lisecned mariner being prescribed Marinol, temporarily, and terminates the prescription before his next hitch? Or something?? i have nerve pain related to shingles, cannabis helps a lot, but that’s a no no. Marinol is a prescription synthetic version of THC. I wonder if it’s worth getting a prescription?[/QUOTE]

This won’t give you a definitve answer, but it indicates that you will need to go through a complicated process. Note in particular the part about DOT disclosing the usage and discussing possible safety risks with your employer:
