Will "Cesamet" show up on my work urinalysis as THC as its a man made cannabinoid?

Hello davidjonasarmstrong & welcome to the site. Sorry no one has answered your question, & hope you passed your urine test. For future use, if you have been prescribed this med, and it's legal in your state, then there should not be a problem if you have it in your system. This is what I found about elimination, & hope it helps you:

Elimination: The route and rate of the elimination of nabilone and its metabolites are similar to those observed with other cannabinoids, including delta-9-THC (dronabinol). When nabilone is administered intravenously, the drug and its metabolites are eliminated mainly in the feces (approximately 67%) and to a lesser extent in the urine (approximately 22%) within 7 days. Of the 67% recovered from the feces, 5% corresponded to the parent compound and 16% to its carbinol metabolite. Following oral administration about 60% of nabilone and its metabolites were recovered in the feces and about 24% in urine. Therefore, it appears that the major excretory pathway is the biliary system.

The effects of age, gender, hepatic dysfunction, and renal insufficiency on the metabolism and elimination of nabilone have not been determined.

Wishing you the best...
