Poppy seeds come from the opium poppy plant and contain a trace amount of opioids, so it doesn't take much to test positive for drugs after eating a poppy seed bagel, according to the U.S. Anti-Doping Agency.
A positive test for drugs is 300 nanograms per millimeter at St. Joseph's, Rossiter-Pratt said. Studies have shown that a teaspoon of poppy seeds can cause your levels to reach 1,200 nanograms per millimeter, WBAL reported.
After the hospital realized Eden’s drug test was a false positive due to poppy seeds, her case worker closed the file.
Eden said the experience was "traumatizing," and she wrote a letter to the hospital outlining her ordeal and to warn others to be aware of the affects of poppy seeds.
