Urine Toxicology Pearls

Urine Toxicology Pearls

Drug seekers will love this post.
EMedHome.com recently published a set of pearls about urine drug testing that included several things I wasn’t aware of.
Did you know that …
  • Urine levels of “ecstasy” (MDMA) need to be quite high before they will be picked up by the urine drug screen since the tests have a low sensitivity for MDMA?
  • Zantac, Prozac, and labetolol can all cause false positive results for amphetamines?
  • Zoloft and Daypro can cause false positive drug screens for benzodiazepines?
  • Several benzodiazepines are difficult to detect on urine drug screens – including Librium and Versed?
  • Levaquin, Cipro, dextromethorphan (common in OTC cough meds), rifampin, and verapamil can all cause false positive tests for opiates?
  • Standard urine toxicology screens do not usually detect Vicodin, Tramadol, Fentanyl and Percocet?
  • Ingestion of one poppy seed bagel can cause a false positive opiate test?
  • Most drugs are undetectable 3 days after use?
Links to some of the cited articles are here, here, and here.
By the way … if you came across this post in a web search on how to beat drug tests and now think you’ve got it made – don’t worry. There are plenty of other ways that doctors can tell whether or not you’re using drugs.
I’m not giving away all of our secrets.
