Some hospitals randomly test newborn babies to see if they were exposed to marijuana in the womb.     If the baby tests positive for marijuana exposure then there may be an investigation done by child protective services.     This may see fine to many, but now a study has found that the use of baby shampoo and soaps may cause a false positive in these tests.    Time Magazine reports that the false positives are not only in the baby products but in other soaps and shampoos.   They also say that the false positive will not be found in more sophisticated tests that are done in outside laboratories.     They soaps may cause false positives for marijuana exposure, but researchers have said that they do not have do not cause the intoxicating effects of marijuana exposure.

Some of the products that gave the false positive in the study are:

  • Johnson & Johnson’s Bedtime Bath
  • Johnson’s Head-to-Toe Baby Wash
  • CVS Night-Time Baby Bath
  • CVS Baby Wash
  • Aveeno Baby Soothing Relief Creamy Wash
  • Aveeno Baby Wash & Shampoo
