DATA AND METHODS Seven quarters of (NCS) data were combined into two groups pre- and post-legalization periods - to examine changes in cannabis use (overall, daily or almost daily (DAD)), source of product, driving after consumption and riding in a vehicle with a driver who had consumed. RESULTS By 2019, overall cannabis use had increased (16.8% vs. 14.9%), particularly among males, adults aged 25 and older, and in Newfoundland and Labrador, Nova Scotia, New Brunswick, and Alberta. DAD use, at 6.0%, remained stable, as did the prevalence of driving within 2 hours of consumption (13.2%). Riding in a vehicle with a driver who had used declined, overall (from 5.3% to 4.2%) and among females, persons aged 25 and older, and in Newfoundland and Labrador, Ontario and Alberta. Where Canadians reported obtaining their cannabis also changed, with increasing percentages reporting getting some or all of their cannabis from legal sources, and fewer using illegal sources or relying on friends/family. Some provinces experienced more change than others. DISCUSSION While too soon to observe the longer-term impacts associated with the Cannabis Act, early indications based on data collected in the months surrounding enactment suggests some cautions and also some assurances. Ongoing monitoring will be essential particularly given the 2.0 Act modifications and the ever-changing provincial retail and regulatory landscapes.BACKGROUND Parents are central to healthy development in early childhood.
