Researchers examined records of more than 21,000 mothers who gave birth at a large academic medical center from 2014 to 2020. They found that 7.3 percent of babies born to Black mothers received newborn drug testing compared to 1.7 percent of babies born to White mothers.
Racial differences in newborn drug testing remained consistent after the enactment of recreational cannabis legalization in 2018. Newborn drug tests were more likely to be positive for THC after the passage of recreational cannabis laws but the racial disparity in testing remained the same.
“This study finds racial disparities in newborn drug testing unrelated to obstetrical risk,” the authors concluded. “Our findings strongly suggest that changes in policies regarding drug testing and reporting at the hospital and state level and improvement measures focused on the health, well-being, and dignity of Black birthing people are needed to reduce health inequity for Black parents and their newborns.”
