As cannabis use rises in popularity, it is increasingly important to understand its health impacts. To create a realistic simulation of human cannabis use, researchers delivered vaporized cannabis to a population of pregnant rats using e-cigarette technology. Offspring exposed to vaporized cannabis exhibited higher degrees of emotional reactivity and social timidity as juveniles, and anxiety-like behaviors in adulthood, compared to those exposed to vehicle exhaust vapor or no vapor. While this study provides early information on prenatal exposure to cannabis, more research is needed to draw reliable conclusions about long-term health effects.
