Cannabis use during pregnancy may affect pre-natal growth and development. Though more research in this area is needed, cannabis use during pregnancy and breastfeeding may be associated with increased risk of the following outcomes:
- Low birth weight
- Pre-term labour
- Long-term health problems (cardiovascular and mental health)
- Short and long-term learning, development, and behavioural issues
It isn’t possible to predict with certainty which individuals will experience harms from cannabis, but risks associated with cannabis use during pregnancy and breastfeeding has led to the recommendation to avoid using cannabis use if you are pregnant or breastfeeding.
