Hello from JustAnswer. This is Dr. Love.

There is no evidence that an antiseptic mouthwash would cause a false positive salivary drug test for cocaine. It is important to realize, though, that there is a fair amount of false positive tests, even in people that are not taking any medicines or recreational drugs. It is intrinsic to the nature of the test, which is why a confirmatory test should be done for any positive screening test result. We really do not know why most false positive occur, particularly in people that do not take any other medicines or recreational drugs, but once the confirmatory test shows a negative result, we also do not worry about the reason for the false positive result.

You do not say why the test was done, but she should insist that a confirmatory test be done, such as GC/MS.

If I can provide any additional information, please let me know.
