Ontario, Canada: The adoption of medical cannabis access in Canada was associated with reductions in alcohol sales, according to data published in the journal Health Policy.
A Canadian researcher evaluated the relationship between medical cannabis legalization and retail sales of alcohol in various regions of the country over an eight-year period.
The author determined: “This study found a significant negative association between legal medical cannabis sales and liquor store alcohol sales: each cannabis sales dollar was associated with an average alcohol sales reduction of between $0.74 and $0.84. The negative association was robust with respect to several alternative modeling choices.”
He concluded, “From a public health perspective, the results likewise imply that reductions in alcohol-related health impacts might partly offset the increased cannabis-related health impacts that legalization might bring.”
A 2017 analysis of US beverage sales identified a similar decline in alcohol sales following the adoption of statewide medical cannabis legalization laws, as did a 2021 assessment of Youth Risk Behavioral Survey data. By contrast, a more recent study evaluating the impact of adult-use legalization laws in the United States reported an association with increased alcohol use those age 21 and older.
