With the legalization of cannabis in Canada, being aware of the potentially harmful effects of cannabis on a healthy pregnancy and your baby’s development is important.
While research still doesn’t give us all the answers about the effects of cannabis or CBD on pregnancy and the baby’s development, for now, the only safe amount of cannabis to use while pregnant or breastfeeding is zero.
Why take the chance?
There is not enough clinical evidence to accurately determine the beneﬁts or risks of using cannabis while pregnant or when breastfeeding. Among other reasons, there aren’t standard levels of THC (the main, active ingredient) in cannabis.
Pregnant and breastfeeding women may be hesitant to report if they use and how often they use cannabis, and it is very difﬁcult to factor out the effects of also using tobacco while pregnant or when breastfeeding.
Until we have more definitive answers, not using cannabis or CBD during pregnancy or when breastfeeding is the safest option for you and your baby.
Effects on your baby:
Cannabis in all forms may affect your baby’s brain development and may result in learning and behavioural issues that last throughout their life. Some studies have shown that the use of cannabis during pregnancy, and while breastfeeding, may be associated with increased risk for the following issues:
- Low birth weight
- Preterm labour
- Long-term health problems related to cardiovascular and mental health
- Short- and long-term learning, development, and behavioural issues including low IQ scores, impulsivity and hyperactivity in childhood, some of which may persist into adulthood.
We’re working hard to understand the science, but we’re just not there yet. Not using cannabis during pregnancy and while breastfeeding is the safest option for you and your baby until we know more.
