Cannabis use disorder among insured pregnant women in the US between 2015–2020

Cannabis use has been increasing during pregnancy, according to researchers at Columbia University Mailman School of Public Health and the Columbia University Irving Medical Center. Previous research has observed that past-month cannabis use has more than tripled among pregnant women in the U.S. from 2002–2020, with self-reported cannabis use rising from 1.5% to 5.4% over the 18 years of tracking data.
