Does Ecstasy ever contain PCP?
Q: I recently ate a White Superman "roll", which is the word I choose to call Ecstasy, since X isn't always MDMA these days. I was told it that it contained heroin, and it sure felt like that was the case. A friend who ate the same kind of roll had to take a drug test, and he tested positive for PCP use. Since he hadn't taken any PCP, he felt sure that the PCP must have been from the roll. Have you ever heard of any Ecstasy containing PCP?

A: None of the assorted "Superman" Ecstasy tablets with analyses posted at (between 1999 and 2008) were reported to contain PCP. However, several contained chemicals other than MDMA, including BZP, caffeine, diphenhydramine, ketamine, MDA, MDE, methamphetamine, and TFMPP.

As of April 2, 2009, there were only 18 tablets described at that contained PCP (out of 1657 tablets tested). The PCP results were all reported between 2000 and 2003, so we have not seen PCP as a component of an Ecstasy tablet for a while, and it doesn't appear to be a common adulterant; however, it is possible that it could be making the rounds again. has only reported a single occurrence of a tablet containing heroin, so heroin-containing 'rolls' are nearly unheard of.

Other substances can give a false positive result for PCP in some types of drug tests. The immunological assay for detecting drugs of abuse in urine that is most widely used is the EMIT test, which has been pegged as having a 4-34% false positive rate according to Ur-ine Trouble by Kent Holtorf. PCP is only detectable in urine for 3-7 days after use. If your friend was tested more than a week following his consumption of the roll, it is possible that the tablet contained a substance that causes a false positive, such as dextromethorphan (DXM) or ketamine, which are both often found in ecstasy tablets. Both of these can produce sedative-type effects that might subjectively be mistaken for heroin. Medications that can cause false positives for PCP include duloxetine (Cymbalta) and venlafaxine (Effexor).

Although focuses entirely on lab-tested materials, there are other sites, such as and, that include subjective pill reports from users. Keeping in mind that such reports ARE subjective, they may nevertheless help to paint a picture of what one might be dealing with in times of uncertainty.
