OTIS, Teratology Society, SMFM, NSGC Team Up to Shed Light on Prenatal and Postnatal Marijuana Exposure Effects

BRENTWOOD, TN – From plant form to CBD oil, with increasing legalization of marijuana across U.S. states, there comes the need for more information on its impact should a consumer become pregnant. Birth defects experts from the Organization of Teratology Information Specialists (OTIS), the scientific non-profit society that provides the MotherToBaby no-cost service, are offering the latest data surrounding marijuana exposure in pregnancy and lactation during a free webinar for healthcare providers on May 2, 2019 at 12p Pacific/3p Eastern.

“If I use edibles instead of smoke marijuana, that should be safer during pregnancy and breastfeeding, right?” – It’s just one of the many questions the MotherToBaby service, which answers questions about exposures during pregnancy and breastfeeding via phone, text, live chat and its website, is now receiving on a regular basis according to Christina Chambers, PhD, MPH, MotherToBaby president and professor of pediatrics at the University of California, San Diego. Dr. Chambers also heads up Mommy’s Milk Human Milk Research Biorepository, the first-ever research database of human breast milk which produced a ground-breaking study last year suggesting that marijuana can linger in breast milk for far longer (up to six days) than previously thought. “As more states legalize marijuana for medicinal and recreational use, it’s critical we look at how it’s impacting the next generation,” she said.

The webinar, “Sifting through the Smoke: The Latest Research Surrounding Marijuana Exposure in Pregnancy and Breastfeeding,” is a collaboration with the National Society of Genetic Counselors (NSGC) and, in addition to OTIS/MotherToBaby, will include presenters representing the Teratology Society and the Society for Maternal-Fetal Medicine (SMFM). The webinar is free and aimed at healthcare providers and researchers; registration is required at the following link:

“Older studies have suggested that if a mother uses marijuana during pregnancy, she might be at risk for having a smaller baby born early and/or having it experience developmental delays,” said Sarah Obican, MD, a Maternal-Fetal Medicine subspecialist at the University of South Florida, director of MotherToBaby’s Florida affiliate, and Dr. Chambers’ co-presenter for the webinar. “However, marijuana is produced today at a higher potency level, so it’s critical we stay vigilant in our research to better understand its impact,” she added.

The webinar is expected to run approximately one hour and presenters will be available to answer questions from attendees.
