Almost 4 percent of women between the ages of 18 and 44 and who were expecting a baby reported in 2014 they had used marijuana in the past month, compared with 2.4 percent in 2002. Researchers used data from 10,587 pregnant women.
The results are troubling to medical professionals, however. Previous studies have shown that infants who were exposed to marijuana were more likely to be anemic, have lower birth weight and be placed in neonatal intensive care than infants of mothers who did not use.
“Some sources on the Internet are touting marijuana as a solution for the nausea that commonly accompanies pregnancy,” Nora D. Volkow, director of the National Institute on Drug Abuse said in an online editorial. But “doctors must be aware of the risks involved and err on the side of caution by not recommending the drug for pregnant patients.”
