Cannabis Legalization in Canada: Are We Seeing More Harm Than Expected?

Описание: How has cannabis legalization impacted public health? In this powerful presentation, Dr. Daniel Myran, a public health physician and researcher, unpacks the data behind hospital visits, poisonings, psychosis, and cannabis-involved driving since legalization in Canada.

Using national health administrative data, Dr. Myran reveals critical trends:
🚸 A 9-fold increase in pediatric cannabis poisonings, with legal edibles contributing significantly—especially outside of Quebec, which imposed stricter edible regulations.
🧠 Rising cases of cannabis-induced psychosis and a troubling link to long-term schizophrenia, especially in young males.
🚑 Significant increases in hospital visits for hyperemesis syndrome, a severe vomiting condition tied to high-potency cannabis use.
🚗 A 500% increase in cannabis-involved traffic injury emergency visits, raising concerns about impaired driving.

Dr. Myran also discusses whether commercialization—rather than legalization alone—may be driving these harms. He argues that strict regulations, like Quebec’s model, are effective in mitigating some risks while preserving the benefits of legalization, such as reducing criminal penalties.

This video is essential viewing for anyone interested in public health, cannabis regulation, policy reform, and the real-world effects of cannabis legalization.
