Cannabis, nicotine use during pregnancy found to increase rate of infant death fourfold

Oregon Health & Science University researchers found that using cannabis and nicotine together during pregnancy increases risks for poor newborn outcomes. The study, published in JAMA Network Open, revealed infants faced higher chances of small gestational size, preterm delivery, and death. Data from over 3 million pregnant patients showed a fourfold increase in infant death risk for users of both substances compared to non-users. Health care providers are urged to counsel patients on quitting either substance to reduce risks. The research aims to inform clinical recommendations and interventions for healthier pregnancies amid ongoing investigations on combined substance usage effects.
