Knowledge and Use of Cannabis in Pregnancy: An Ontario Public Health Needs Assessment in Partnership with the Society of Obstetricians and Gynaecologists of Canada

Studies show poor maternal and fetal outcomes associated with prenatal cannabis use. With the legalization of cannabis in Canada, it is of timely importance to increase awareness of the effects of its use in pregnancy. An anonymous, online questionnaire was used to assess the pregnant population's knowledge, beliefs, and risk perceptions concerning cannabis. Additionally, educational materials on the effects of prenatal cannabis use were evaluated. A potential knowledge gap was found among 9%-19% of participants, who reported that cannabis posed no risk of harm to the pregnant person or fetus. Moreover, minor changes could improve the effectiveness of educational resources.
