Changes in population-level alcohol sales after non-medical cannabis legalisation in Canada.

ABSTRACT:

Introduction

There is considerable interest in whether individuals substitute cannabis for alcohol and in legalisation's potential to reduce or increase alcohol-attributable harms. This study aimed to determine whether non-medical cannabis legalisation in Canada was associated with initial changes in population-level alcohol consumption.

Methods

This observational population-based study described changes in alcohol sales in Canada between 2004 and 2022. We calculated annual changes in the per capita volume of pure ethanol sold in Canada. We used an interrupted time series approach to examine immediate and gradual changes in per capita price-adjusted alcohol retailer sales value (CAD$) and beer producer sales volume (litres of product) after legalisation.
