How long does the drug from poppy seeds stay in your system?

I believe when you schedule a drug test that they say 24 hours for things like that. However, any time you take a drug test there’ll be a form you fill out asking if you’ve taken anything that could cloud your results falsely: prescriptions, foods, etc. Just put down anything you can think of. Or, you could try to find a way to flush.

Poppy seeds contain morphine. If you eat poppy seeds, you will excrete morphine in your urine, which may result in a positive urine test for opiates. However, the morphine level in your urine after eating poppy seeds is very low — typically below the detection threshold for most drug screening tests — and the morphine is usually cleared from your body within four hours.
To avoid any problems, don’t eat poppy seeds before a drug test. If you are required to provide a urine sample after recently eating poppy seeds, tell the person collecting the sample or the doctor overseeing the testing that you recently ate poppy seeds and to take that into account.
By the way, the amount of morphine in poppy seeds is extremely low, so they won’t give you a morphine “high” — no matter how many you eat.

The poppy seeds should already be out of your system. It should stay in your system for as little as 4 hours to as long as 96 depending on how many you ate. Tell your doctor, or whoever is doing the test that you had poppy seeds about a week ago. I am sure everything will be fine, so don’t worry.
