do poppy seeds make you test positive for weed

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.

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.

However, it may be possible to exceed the morphine threshold by eating foods with poppy seeds and USADA can’t predict how long morphine or morphine metabolites from poppy seeds will stay in your system. The most conservative approach would be to avoid poppy seeds a few days before and during competitions.

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

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.

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.

Research shows that morphine and codeine can sometimes be detected in the urine up to 48 hours after ingestion of poppy seeds from some pastries, such as bagels, muffins, and cakes (see reference one for a free article on this topic).

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.

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.

These medications usually won’t interfere with your drug screens. But in rare cases, a few antibiotics are known to trigger inaccurate test results. Rifampin, which treats tuberculosis, might show up as opiates in some rapid urine screens. What’s more, the false positive result may be possible even more than 18 hours after you’ve swallowed a single dose of the antibiotic.

False-positive drug test results have been reported in multiple drug classes. Some of the more common classes include cold and allergy products, pain medications, and drugs for infections:

As previously mentioned, confirmatory testing with GC-MS will identify individual drugs or metabolites in a sample, and almost eliminate the chance for a false positive result.

There have also been reports of people using products such as Visine eye drops to adulterate urine samples to cause a false-negative result for THC from marijuana. Ingredients in Visine, such as the preservative benzalkonium chloride or the borate buffer may decrease the concentration of 9-carboxy-THC in the initial urine immunoassay; however, upon confirmatory testing with GC-MS this metabolite will still be detected. 1

The increased use of onsite, workplace random drug testing and home-testing kits emphasize the need for reliable, confirmatory testing. Negative consequences of false-positive drug testing can include 1 :
