poppy seed test


Definition Poppy seed test is a popular term for a urine test for morphine and codeine which is positive both in individuals who have recently used heroin and in those who recently ate poppy seeds, which are found in various baked products, in particular poppy seed bagels.

Until 1998, the US National Institute on Drug Abuse–NIDA set the cutoff for detecting opiates at 300 ng/ml. The problem with this cutoff was that a person consuming poppy seeds–e.g., 3 teaspoons, has levels of up to 1200 ng/ml 6 hours after the poppy seedfest, resulting in false positive results for heroin use and giving rise to the so-called “poppy seed defence” that has been by attorneys zealously defending those accused of heroin abuse. The NIDA has revised its cutoff for codeine and morphine to 2,000 ng/ml; the US military bumped its cutoff to 3,000 ng/ml to avoid the false positive issue. The best way to differentiate heroin use and casual poppy popping is to measure 6-MAM (6-O-monoacetylmorphine) in the hair, which is an indicator of long term heroin abuse. 6-MAM can be measured in the urine, but is only positive on the day of ingestion.
