This seminar assesses the early public health impacts of the legalisation of cannabis production, sale and use in Canada and 24 states in the USA.

It addresses the following questions:

  • How did cannabis legalisation come about in the USA and Canada?
  • What regulatory models have been adopted?
  • What have been the short-term effects of legalisation on cannabis markets, products, and prices?
  • How has legalisation affected patterns of cannabis use and cannabis related harms to physical and mental health?
  • What may be the longer-term effects of cannabis legalisation over the next decade or so?
  • What are the potential implications for Australian cannabis policies?
