Association Between Self-Reported Prenatal Cannabis Use and Maternal, Perinatal, and Neonatal Outcomes
A 2018 Canadian study reports increased incidence of preterm birth and low birth weight among children prenatally exposed to cannabis. The legalization and subsequent increase in use of cannabis calls for further studies investigating the effects of maternal cannabis use on infants; however, covariates make it difficult to make definitive conclusions. Individuals who use cannabis during pregnancy are also more likely to be younger, low-income, and receive inadequate medical attention during pregnancy, all factors which can impact birth weight and gestational length. Although evidence may point to cannabis use during pregnancy influencing preterm birth and birth weight, many other factors can impact these outcomes.
