Even though most of the opium is removed from the poppy seeds during processing (usually more than 90%), in some cases, the seeds sold for use in foods still have a significant amount of opium – and thus morphine – on them. The amount of morphine residue left on the seeds depends on how well the poppy seeds are cleaned and processed, which varies depending on the country the seeds are from and how and when they were harvested.

Can the morphine from poppy seeds be detected in a sample?

USADA cannot predict the amount of poppy seeds you can eat and remain below the testing threshold set by WADA. **In most cases, consumption of poppy seeds in foods will not cause a positive doping test.

The opium is composed of roughly 12 percent morphine, which is a narcotic that is prohibited in-competition. According to the World Anti-Doping Agency (WADA) Prohibited List, morphine is a threshold substance, meaning that WADA-accredited laboratories determine if a sample is positive for morphine when the level of morphine in the urine is greater than *1.3 micrograms/mL.

While poppy seeds don’t actually contain morphine, the seeds can become coated by, or absorb, opium extract during harvesting. Opium is the milky substance that is extracted along with the poppy seeds from the seed pod of the opium poppy after all the petals have fallen off.

This beverage is a popular folk remedy in Peru and elsewhere in South America. It’s made with the leaves of the same plant that cocaine comes from. If you drink it, you may want to stop a couple of days before your drug test. Coca tea could affect your screening for up to 36 hours after you’ve sipped it.

Sertraline (Zoloft) is prescribed for depression, panic attacks, obsessive-compulsive disorder, and more. Some drug screens may not be specific enough to tell apart sertraline and benzodiazepines. The latter is an older tranquilizer drug that’s often found in people who overdose on opioids. The faulty test result could happen for several days after you quit your antidepressant.

But having a few G&Ts could also liven up your drug test results.

The construction worker added, “I knew straight away that it had to be the poppy seeds I had eaten and I actually thought 'Great that explains it.'”

So, can eating poppy seeds really lead you to fail a drug test?

And even poor, innocent, tonic water can help you to fail a drug test.

Tonic water was originally drunk for its quinine, an antimalarial drug derived from the bark of the South American cinchona tree.

After receiving the positive results, the Liverpudlian paid £120 for a private hair-follicle test, which came back negative, and obtained a letter from his GP stating he had never been on any prescribed medication, such as morphine or painkillers – which contain opium.

“It is unlikely that a single poppy seed roll, or even a dozen rolls, would result in an individual ingesting enough morphine to have a pharmacological effect.”
