PCP...
It can show up as PCP in drug screens
Yes! Lamictal will show a false positive on drug screens. You can have a lab use a maspectrometer specifically for PCP in order to officially rule it as a "false positive."
Yes
can percocet cause a false positive for pcp
Nothing, large amounts is possible to show a false positive for PCP though (unlikely).
It can cause a false positive for PCP or Opiates depending on the quality of the test.
yes, but it is out of your system with in 3 - 7 days
Unless a person placed PCP in their mouth and kept it there while french kissing, testing positive from kissing someone who has used PCP shouldn't be a concern.
AnswerI take effexor xr. It is along the lines of an ssri. It cross reacts with the pcp test and can yield a false positive result.AnswerSame with Cymbalta, an SSNRI which also affects dopamine uptake in addition to serotonin and norepinephrine. Also, just in case - ketamine will definitely show up as PCP, as the two drugs are chemically related.AnswerTaking over the counter cough medicines, anything contained Dextromethophan(DXM). Or if you have been given Ketamine, recreational or from the hospital.Many ecstasy pills out there are not pure MDMA and are "piperzines" which contain PCP. You can get testing kids that check to see if the pills you have contain PCP and other harmfull drugs. If you buy cocaine sometimes its not exactly pure and it can be cut with PCP.AnswerDextromethorphan (cough syrup), diphenhydramine (Benadryl) and ibuprofen (Advil) all cross-react with PCP tests. If I had to take a stab, I'd say you took some Advils.
