Had to look it up and seems Parsifal is right that you would been to eat a lot of poppy seeds to get a buzz but apparently you don't need to eat that much to get a positive drug test.It’s possible that even just one bagel or muffin highly loaded with poppy seeds can lead to a positive urine drug test.
Drug screening is becoming more common as part of the recruitment process for jobs. It’s also required if you’re trying to qualify for medical or life insurance.
If you’re going to be taking a drug test, it’s a good idea to avoid any products containing poppy seeds for at least two or three days before the test. That poppy seed cake may taste delicious, but it could cost you your job or insurance coverage.
