No: Some people think because it has "caine" in it that it could show up as cocaine, but it is a completely different chemical with no overlap with any drugs of abuse. Test kits do not test for it, and confirmatory tests like gas chromatography/mass spectroscopy will determine exactly what it is if there is any question on the screening tests.
