In certain instances, the answer is yes; poppy seeds will show on a drug test. The consumption of poppy seeds can cause a person to fail a drug test because such seeds can contain small amounts of morphine, which will show up as an opioid on a drug screen. Whether or not poppy seeds will produce a false positive drug screen depends on the amount, type, and frequency of consumption. If you are worried that your drug test might be falsely positive, it is best to avoid ingestion of poppy seeds or discuss any recent consumption of poppy seeds with your provider. Your provider might then decide to order additional confirmatory testing.
