Eating poppy seeds will not always result in a failed drug test. : The common myth about eating poppy seeds can lead to failing a drug test has a solid foundation in reality, as heroin, morphine, codeine, and other opiates are created from the plants. But Indiana University sheds some light on the reality of the situation, pointing out that only the seeds of opiate poppies cause false positives. For those who have eaten the offending poppyseeds, however, there are ways to determine whether or not the opiate traces come from narcotics or a harmless bagel.
