Since the legalization of cannabis in Canada in 2018, there has been a rise in cannabis use across different populations, including pregnant women. A recent study revealed a troubling increase in cannabis use disorder (CUD) among pregnant individuals, jumping by more than 20% after legalization. As cannabis becomes more accessible, it's important to understand the risks associated with its use during pregnancy and how it can affect both mothers and their babies.
What is Cannabis Use Disorder?
Cannabis use disorder (CUD) refers to a pattern of cannabis use that leads to significant impairment or distress. Symptoms include cravings, an inability to reduce usage, and continued use despite harmful effects. This disorder, which can develop with regular use, becomes especially concerning during pregnancy because of the potential impact on both maternal health and fetal development.
Why Cannabis Use During Pregnancy is Risky
Cannabis, particularly its psychoactive component THC, can cross the placenta and affect the developing fetus. Some of the potential risks include:
- Low birth weight: Babies born to mothers who use cannabis during pregnancy are more likely to have lower birth weights, which can lead to other complications.
- Preterm birth: Cannabis use has been associated with a higher risk of preterm labor, which increases the chances of developmental delays and long-term health issues.
- Neurodevelopmental issues: Exposure to cannabis in utero has been linked to problems with attention, memory, and behavior as the child grows.
One of the biggest concerns is that cannabis may interfere with the development of the baby's brain, leading to cognitive and behavioural issues later in life. Additionally, using cannabis during pregnancy could increase the risk of attention deficit disorders, such as ADHD, and may be linked to autism spectrum disorders.
