Will poppy seeds show up on a routine drug test i ate poppy seeds for lunch then i had a drug test later on that day. now i am worried that i might fail it because of the poppy seeds.

Even : Even though the drug, opium, is from a different part of the poppy plant, there is a possibility of failing a drug test after eating poppy seeds. It was actually tried on a myth busters episode and has been written about on snopes.Com (see below)! luckily, many tests have taken this into consideration, so will only register much higher levels of opiates as an actual "positive" on a drug test than you can get from eating poppy seeds. Good luck!

Yes: Depends, however, on the cut off level used for opiates in the urine and of course how dilute the urine was.
