Cocaine metabolite can likewise be recognize in the pee specimen that the medical professional who is performing the procedure.4 Jacobson, et al, studied the effect of use of ophthalmic solution containing cocaine on pee excretion of benzoylecgonine in patients. Out of 50 subjects studied, 47 topics (94%) prove a hopeful screening result for cocaine (as benzoylecgonine) 4 to six hours after receiving eye drops.

Therefore, usage of Novocain during dental measures or usage of various other anesthetic agents, consisting of benzocaine, tetracaine, and lidocaine, need to not cause false-positive cocaine test outcomes in to pee DOA testing.


Both urine and saliva drug testing methods will have actually false positives/negatives native time to time, and in most instances will it is in the same for urine and saliva. Saliva exam seem come have more false negatives as result of the ease of diluting or transforming the sample against the person being tested.
