Study finds increased cannabis use during pregnancy

Cannabis use more than doubled among pregnant women in the United States during the period 2002-2017, according to data collected from 467,100 women aged 12-44 who participated in the National Survey on Drug Use and Health (NSDUH). After adjusting for age, race/ethnicity, and family income, past-month cannabis use, daily/near cannabis use, and number of days of cannabis use all increased among pregnant women. Cannabis use was more common during the first trimester than during the second and third. In addition, cannabis use for medical purposes was relatively rare, but just as frequent among pregnant as non-pregnant women.
