Strange Reason for Baby’s Positive Pot Test | Baby Soap
Certain soaps usedِ toِ wash babies shortly afterِ birth mayِ causeِ the baby toِ test positive forِ marijuana onِ some newborn screening tests, a newِ study suggests.
In theِ study, urine samples thatِ contained minute amounts ofِ anyِ of fiveِ baby soaps — Johnson & Johnson’s Head-to-Toe Baby Wash, J&J Bedtime Bath, CVS Night-Time Baby Bath, Aveeno Soothing Relief Creamy Wash andِ Aveeno Wash Shampoo — gave a positive result onِ a drug screening test forِ tetrahydrocannabinol (THC), theِ active ingredient inِ marijuana.
The amount ofِ soap inِ the urine needed toِ produce a positive test result wasِ tiny, lessِ than 0.1 milliliters, theِ researchers said.
Why the result?
The researchers aren’t sureِ why theِ baby soaps causeِ the marijuana screening test toِ comeِ backِ positive.
It couldِ beِ that someِ ofِ the compounds inِ the soap haveِ a structure thatِ isِ partly similar toِ THC, orِ itِ couldِ beِ that chemicals inِ the soap change theِ way theِ test works, Hammett-Stabler said.
The test isِ likely showing a positive result becauseِ some residual soap onِ the skin isِ washing offِ intoِ the baby’s urine sample, Hammett-Stabler said.
Piece of the puzzle
One positive test forِ marijuana exposure wouldِ notِ likelyِ beِ enough toِ getِ social services involved withِ theِ parents, Seashore said.
It would only be one piece of the puzzle, Seashore said.
Other factors wouldِ beِ taken intoِ account, suchِ asِ a history ofِ substance abuse orِ lack ofِ prenatal care, Seashore said.
The UNC Chapel Hill nowِ sends allِ positive newborn drug urine tests forِ conformation beforeِ anyِ action isِ taken.
The study, published inِ the June issue ofِ the journal Clinical Biochemistry, alsoِ highlights theِ importance ofِ collaboration andِ communication betweenِ different units ofِ a hospital, theِ researchers said..
