Babies testing positive for cannabis use
A SHOCKING number of babies are testing positive for marijuana use, according to a scientific study in the United States.
Baby wash, baby shampoo and bedtime bath soap are all seemingly innocent products used every day.
But scientists at the University of North Carolina have found them to be the culprit behind a spike in false positive marijuana results in babies’ urine, says the study published in the journal Clinical Biochemistry.
The study found it had to do with how baby urine is captured.
Tests for tetrahydrocannabinol (THC) – the active ingredient in marijuana – usually get more than just urine, and these tests were capturing the soap residue on the babies’ skin.
The scientists say none of these soaps actually contain any marijuana, it is just that something in the soap triggers the false positive.
They ultimately decided this was an important study to let hospitals know that when a test comes back positive for marijuana they should do a blood test too. |
