depends on the type of drug test....and i correct my previous statement, on the show MythBusters apparently ppl who ate 3 poppy seed bagels tested positive for opiates in the same day. maybe there is hope for that excuse...
Poppy seeds cause false positives for opiatesPoppy seeds do contain trace amounts of morphine, but it would require about 100 poppy seed bagels to reach enough to cause a positive (failed) test result. Poppy seed-filled pastries (such as hamantashen), on the other hand, do in fact contain enough to potentially cause a false positive.[33]
An episode of MythBusters tested this legend, and found that as little as three poppy-seed bagels was enough to cause a positive result for the remainder of the day they were eaten (though participants tested clean the following day).[39] The results of this experiment are inconclusive, however, because a test was used with an opiate cutoff level of 300 ng/mL instead of the current SAMHSA recommended cutoff level used in the NIDA 5 test, which was raised from 300 ng/mL to 2,000 ng/mL in 1998 in order to avoid such false positives from poppy seeds.[40] Nonetheless, as stated before, foods with a very high density of poppy seeds are best to be avoided as they can potentially cause one to cross even the higher threshold.
