Benzo False Positive Benadryl

Updated

How much Benadryl would have to be taken for a positive Benzo. result? And if that person had not been taking Benadryl for 6 days, would you still expect a positive result?

Since most of the substances that cause false positives are learned through anecdotal experience and testing is only done later, the precise amounts that may cause it usually aren't known, however, it's been known to happen with a single, regular dose of 25mgs.

As to how long you may get a false positive result, the half-life of Benadryl can range from 2 to 8 hours and the length of time it takes for something to be processed out of the human body is usually 5 to 6 half lives, so it may be detectable for anywhere from 10 to 48 hours.

Hello. I just had a drug test 2 days ago and it has come up positive for marijuana. I havent smoked anything for over two months. Could the benadryl i take regularly have anything to do with me not passing the drug test?
