Do poppy seeds affect drug tests?
Poppy seeds don’t have nearly enough opiates to intoxicate you. But because drug tests are exquisitely sensitive, consuming certain poppy seed food products can lead to positive urine drug test results for opiates – specifically for morphine, codeine or both.

Under most circumstances, opiate concentrations in the urine are too low to produce a positive test result. But certain food products – and it’s generally impossible to know which ones, because opiate content does not appear on food labels – contain enough opiates to produce positive test results. Moreover, because of overlap in opiate concentrations and morphine-to-codeine ratios, it can sometimes be challenging to distinguish test results that are due to the consumption of poppy seeds from those that are due to the use of opiate drugs.

This is not a problem with most workplace drug testing. Test results are reviewed by a specially trained physician called a medical review officer. Unless the physician finds evidence of unauthorized opiate use, such as needle marks or signs of opiate intoxication or withdrawal, even relatively high concentrations of opiates in the urine that produce positive test results are generally ruled to be negative.

It turns out, though, that drug testing in the military is different, and poppy seeds pose potential problems. One such problem, as highlighted in recent news reports, concerns service members who test positive for codeine and assert a “poppy seed defense.” They are still regarded as having taken codeine, sometimes with serious consequences, such as a disciplinary action or discharge from the service.

Drug tests are extremely sensitive and consuming certain poppy seed foods can actually lead to positive urine drug tests. Other foods can set off a drug test, but it's nearly impossible to tell which ones will. 

During most workplace drug tests, a trained physician will list the results as negative unless they see other evidence of opiate use such as needle marks, intoxication, or very high concentrations of opiates in the system. The military on the other hand may take serious disciplinary action if they find any opioids in a drug test, even if the culprit is only poppy seed foods. 

To answer the question, Yes, poppy seeds can set off a drug test, but it generally does not result in a positive test unless they are being ultra strict.
