Diphenhydramine Fail Drug Test

Updated

i just failed a drug test for thc.. could that had been caused by taking 100mg of diphenhydramine hcl, and 100mg of hydroxyz pam the night before, for sleep? if so, when they send it off to the lab, will they be able to tell that it was not a positive test from marijuana?

NO. It will NOT show positive when testing for THC/Cannabis. Drug testing techniques have advanced dramatically on all fronts. Generally, a positive result indicating THC/Cannabis, to use the example, means the client has been using THC/Cannabis. False positives (with VERY limited exception) due to interaction is these days is a myth.
