Oh, yes, it certainly can. So can several other commonly used medications such as antidepressants. They are chemically related but do not have the effects of cocaine. Getting a confirmatory test or a hair test (these are done with MASS SPECT CHROMATOGRAPHY... think CSI) will get the real answer.
The dipstick screen is NOT reliable.
