“But our study shows that in utero exposure to cannabis has the opposite effect on children, causing them to have increased levels of anxiety, aggression, and hyperactivity compared to other children who were not exposed to cannabis during pregnancy.”įor this study, researchers from Icahn Mount Sinai and CUNY examined placental gene expression and early childhood behavior and physiology in a long-term study of 322 mother-child pairs who were drawn from an ongoing New York City-based study of stress in pregnancy started in 2009.
“We know that cannabinoid signaling plays a role in modulating stress, which is why some people use cannabis to reduce anxiety and relax,” said Yoko Nomura, Professor of Psychology at CUNY Graduate Center and Queens College and first author of the paper. In line with this softening public opinion, cannabis has emerged as one of the most consumed recreational drugs of abuse during pregnancy, yet the impact of maternal cannabis use on fetal and childhood development is not clear. Women who use cannabis during pregnancy, potentially to relieve stress and anxiety, may inadvertently predispose their children to stress susceptibility and anxiety, according to a study conducted by researchers from the Icahn School of Medicine at Mount Sinai and the City University of New York published Monday, November 15, in the Proceedings of the National Academy of Science (PNAS).Īs legalization of recreational cannabis progresses across the world, many people mistakenly believe that cannabis use is without significant health risks.
