no just the thc will cause a positive result and can remain in the system for quite a 2-3 weeks. omeprazole is not even close to the chemical structure of thc. there can be false positive drug tests but those are rare assuming it was tested at a good lab. webmd is incorrect in this instance. i know for a fact that omeprazole and all ppi's (proton pump inhibitors) can most definitely cause a false positive for thc. this is from several physicians (my own pain management doctor for one) and a relative who works for a testing firm that does drug testing for the federal government. yes prevacid or omeprazole can cause a false positive for thc. i tested myself at home in the a. m. and was negative for thc. i tested for the court in the p. m. after taking omeprazole (prilosec) and tested positive for thc. i called the company first check that makes the home test. they told me pantoprazole can cause a false positive but could not say for sure if omeprazole would cause a false positive. they recommend any positive test be mailed to them for mass spectometry testing which could rule out a false positive. twice i was jailed for testing positive and then was released after testing negative the next day when i hadn't taken omeprazole. only one time have i tested positive for thc at my pain clinic. i was extremely embarrassed and shocked! i am 52-years old and have not smoked pot since i was 19. i had just started a trial of omeprazole which my provider asked me about by name. i switched to another acid reducer at her suggestion and had no more problem. now i have done the rounds with these medications and it looks like omeprazole is all that's left. hopefully they will be reasonable. i have ulcerative colitis and gerd!
will omeprazole cause a positive thc result on a drug screen
