Daily or near-daily use of marijuana has increased among pregnant women to 3.4 percent in 2017, and past month usage has nearly doubled, to 7 percent, since 2002.
Current national guidelines advise women who are pregnant not to use cannabis which has been linked to a variety of birth defects.
A new study surveyed both 10 medical professionals and 10 commercial marijuana sellers to understand their perceptions and knowledge of perinatal cannabis use.
The authors of the study suggest that more training and education need to be given to healthcare workers on this topic, since pregnant women often reported their encounters with medical professionals as generally unhelpful.
