A new study from Curtin University has found that children exposed to maternal cannabis use during pregnancy and the postnatal period are three times more likely to develop behavioral disorders. The research, published in Psychiatry Research, analyzed data from over 222,600 Australian mothers and children, revealing a significant link between maternal cannabis use disorder (CUD) and disruptive behavioral conditions.
Key Findings
Lead researcher Abay Tadesse, from Curtin’s School of Population Health, stated that maternal cannabis use disorder increased the risk of childhood behavioral issues such as oppositional defiant disorder (ODD) and conduct disorder (CD).
“Our research showed maternal cannabis use during pregnancy increased the risk of disruptive behavioral disorders by 3.56 times, while postnatal use increased the risk by 2.95 times,” Mr. Tadesse said. “With an estimated one in five Australian pregnant women using cannabis, our findings underscore a growing public health concern.”
Long-Term Implications
Professor Rosa Alati, Head of Curtin’s School of Population Health, emphasized the potential long-term effects of maternal cannabis use on children’s mental health. “Cannabinoid ingredients can cross the placenta and enter breast milk, potentially affecting brain development. This research provides critical evidence to shape health policies aimed at minimizing harm,” Professor Alati said.
The study suggests that intervention strategies should be implemented to reduce cannabis use among women of reproductive age. Additionally, further genetic and environmental research is needed to fully understand the link between maternal cannabis exposure and childhood behavioral disorders.
Broader Context
While the study highlights a significant association, researchers acknowledge that other genetic, environmental, and social factors may contribute to these behavioral outcomes. The findings add to the ongoing debate regarding the risks associated with cannabis use, particularly in vulnerable populations such as pregnant and postpartum women.
