Poppy Seed Drug Test Episode

I want to know how much worse the Drug Test Failure would be say
if they ate a Can of Poppyseed.
Or ate The Poppy Seed Patitza or what I do is take the Can of Poppyseed
and roll it up in Pillsbury Crescent Rolls. As in the Poppyseed Cake and Pastry filling
made by a company Called Solo.
