CHICAGO (AP) — Marijuana’s main mind-altering ingredient was detected in nursing mothers’ breast milk in a small study that comes amid evidence that more U.S. women are using pot during pregnancy and afterward.
The new study involved 50 nursing mothers who were using pot and provided breast milk samples to researchers at the University of California, San Diego. Lab testing found small amounts of THC, the psychoactive chemical that causes marijuana’s “high,” in 34 of 54 samples up to six days after they were provided. Another form of THC and cannabidiol, a pot chemical touted by some as a health aid, were detected in five samples.
The study authors said “it is reasonable to speculate” that exposing infants to THC or cannabidiol “could influence normal brain development,” depending on dose and timing.
The results echo findings in case reports from years ago, when pot was less potent than what’s available today, said study co-author Christina Chambers, a pediatrics professor. It’s not known if the amounts detected pose any risk, but she said her research team is studying children whose moms’ were involved to try to answer that question.
Research has been hampered by federal government restrictions based on its view that marijuana is an illegal drug.
That has contributed to a stigma and shaded doctors’ views, said Keira Sumimoto, an Irvine, California, mother who used marijuana briefly for medical reasons while pregnant and breastfeeding. She said smoking a joint daily helped her gain weight when she was sick before learning she was pregnant, and eased childbirth-related pain, but that she quit because of backlash from marijuana opponents.
