He says there are many good reasons for the FDA to be concerned about home drug tests. If it's a positive, I'm going to say, hey, Johnny, you've been using drugs. Maybe it's not a positive. Maybe it's a false positive. Morin says eating a poppy seed bagel can make someone test positive for opium or heroin use.
Some cough syrups can also cause a false positive.
Morin says it's part of the FDA's legally mandated role to review products to make sure they are labeled effectively to inform parents of such possibilities. He says even products that seem simple, like a Dixie cup urine test, oftentimes raise more complex issues, such as who a home testing company is allowed to share information with. For example, an insurance company finds out that two of your kids seem to be using drugs, because they're testing positive. And they drop those children from your home insurance policy. I mean, there's any number of things that can happened.
