THC in Pregnancy: Mouse Study Reveals Alarming Effects
6 Jan
Summary
- Prenatal THC exposure in mice leads to increased anxiety.
- Offspring show altered decision-making skills post-exposure.
- Below-average birth weight is a noted effect in exposed mice.
Scientists are investigating the impact of THC exposure during pregnancy, using mice as a model. Research at the University of Saskatchewan involves exposing pregnant mice to THC smoke daily throughout their gestation period. The study, now in its second year, aims to uncover how THC affects fetal development and the subsequent behavior of the offspring.
Preliminary findings from these experiments reveal several concerning effects in the offspring of THC-exposed mothers. These include heightened anxiety levels, impaired decision-making skills, and a tendency toward lower birth weights. Researchers measure anxiety through maze tests where exposed mice show less exploratory behavior.
Additional studies from other universities corroborate these findings, suggesting potential links between prenatal cannabis use and later-life issues such as anxiety and cognitive challenges in children. Health Canada also notes risks including lower birth weight and alertness in newborns. Experts emphasize that while more data is needed, current evidence is not reassuring, and advise against cannabis use during pregnancy and breastfeeding.
