Ever since recreational cannabis was legalized across Canada in 2018, researchers have been studying what that decision changed for Canadians.
We’ve learned, for example, that some patients immediately left the medical cannabis system, presumably to use recreational products instead. Conversely, legalization appeared to have no effect on Canadian alcohol sales.
We’ve similarly seen how cannabis retailing has evolved since it became legal.
Retailers suffered from product shortages during legalization’s first six months, but steadily expanded soon after. Canada went from having some 210 stores in April 2019 to 3,500 in April 2023. The ensuing competition pushed prices down 28 percent during that period.
Meanwhile, provincial governments have tried various regulatory approaches. Some initially restricted the number of stores to avoid tempting non-users. Québec still has 10 times fewer stores per capita than Ontario does as a result. Other provinces have set minimum prices to discourage people from overindulging. For example, Ontario won’t let wholesale prices drop below $2.28 per gram.
These developments in business and government policy prompted my latest research. I wanted to understand what effect retail expansion had on cannabis use. To do this, I analyzed consumer responses on government surveys collected between 2019 to 2023. I then compared these responses to the recreational cannabis consumer price index and the numbers of licensed stores in each province.
Did Canadians consume cannabis more widely, more frequently and at younger ages as it became more accessible and affordable? The answer was mostly no.
