Sharp uptick in pregnant women using marijuana during a key time in baby’s development

11/6/18–The number of pregnant women who say they used marijuana over the last two decades has nearly doubled, according to federal data. While still rare, prenatal use is growing. Between 2002 and 2016, marijuana use in pregnant women rose from 2.85 percent to almost 5 percent, according to data from the U.S. National Survey of Drug Use. Of the 12,000 women ages 18 to 44 surveyed, 3,500 who said they used the drug were in their first trimester of pregnancy, a critical time in a baby’s development.
