Does embalming fluid cause you to test positive for PCP?

Embalming fluid typically contains formaldehyde and other chemicals, but some people colloquially refer to "embalming fluid" when discussing a substance called phencyclidine (PCP), which is a hallucinogenic drug. If someone has ingested PCP, they may test positive for it, but the chemicals in actual embalming fluid do not cause a positive test for PCP. Therefore, if the substance in question is indeed PCP, it could lead to a positive test, but embalming fluid itself does not cause such a result.
