A new study conducted by researchers at University of North Carolina has found that certain baby soaps used to wash new born babies soon after their birth may be responsible for the rising number of positive tests for marijuana.
The researchers tested the urine samples of babies and found that those that contained even a small amount of any of the five popular brands of soaps, including Johnson & Johnson's Head-to-Toe Baby Wash, J&J Bedtime Bath, CVS Night-Time Baby Bath, Aveeno Soothing Relief Creamy Wash and Aveeno Wash Shampoo, tested positive for tetrahydrocannabinol (THC), which is an ingredient in marijuana.
The researchers were quick to point out that presence of THC in urine samples did not mean that the babies were "high" or experienced any effects associated with marijuana. "Structurally, these things don't look like marijuana metabolites, but clearly they are being recognized by the antibodies used in the immunoassay. And when testing those reagents in increasing concentrations we did see a positive response, albeit really low, just over the point of positive", lead researcher Catherine Hammett-Stabler said.
