A new study has found that common baby soaps and shampoos are triggering positive results for pot tests conducted on babies.
“Commonly used baby soaps and shampoos, including products from Johnson & Johnson, Aveeno and CVS, can trigger a positive result on newborns’ marijuana screening tests, according to a recent study. A minute amount of the cleansing products in a urine sample — just 0.1 milliliters or less — was found to cause a positive result.”
“Researchers at the University of North Carolina, Chapel Hill, began studying the issue after an unusually high number of newborns in their nursery began testing positive for marijuana exposure. Newborn screening for marijuana at hospitals, particularly among babies of women who are considered at high risk of drug use, is not uncommon: at U.N.C. Chapel Hill, 10% to 40% of newborns are tested…”
“Soaps that were specifically associated with false-positive marijuana test results include Johnson & Johnson’s Bedtime Bath, CVS Night-Time Baby Bath, Aveeno Baby Soothing Relief Creamy Wash and Aveeno Baby Wash & Shampoo.”
“The problem is almost certainly not limited to these products, however. Researchers also tested ingredients used widely in soaps and shampoos, including polyquaternium-11 and cocamidopropyl betaine, which both elicited positive marijuana test results. So far, there is no explanation as to why the chemicals interfere with the test’s function, but importantly, they aren’t intoxicating; they don’t cause symptoms of marijuana exposure in children. The researchers think minute amounts of the substances were simply washing off the babies’ skin into their urine samples and confounding the screens.
(Teenagers will have a new excuse for positive drug tests: “I’ve been using baby shampoo, man!”)
I am joking about the teenagers but the problem is babies could in theory be removed from their mother’s care because of these false positive tests. So the doctors either need to take the screenings further or the women need to know this can happen to defend themselves.
So what do you make of these products causing false positives? Would this worry you? Would you stop using them?
