Footnote 1

Tests for statistical significance were done using regression analyses of the variables across waves of the survey. Follow-up contrasts were conducted to examine year to year comparisons.

Footnote 2

All reported increases and decreases in the text are statistically significant changes unless it is stated that the percentage is “unchanged”. At times the text may state that the difference is unchanged, even though the numbers are not identical. This occurs when the difference between numbers is not statistically significant. The statistical significance is indicated in the text description tables located under each figure. For additional details about the survey and methodology, refer to 2018 Canadian Cannabis Survey, the 2019 Canadian Cannabis Survey, the 2020 Canadian Cannabis Survey, the 2021 Canadian Cannabis Survey, 2022 Canadian Cannabis Survey, and the 2023 Canadian Cannabis Survey.

Footnote 3

When recruited, respondents were informed that the survey was about cannabis. This may have created a participation bias, where people who use cannabis may have been more likely to complete the survey. For this and other methodological reasons, the CCS prevalence estimates for cannabis use may be higher than reported in other Canadian population level surveys.

Footnote 4

The question regarding driving after cannabis use changed from 2018 to 2019, and remained consistent from 2019 onwards (2020, 2021, 2022, and 2023). In 2018, the question only asked if the person drove within 2 hours of any cannabis use. From 2019-2023 two questions were asked: drove within 2 hours of smoking/vaping cannabis and drove within 4 hours of ingesting cannabis. In order to compare 2018 responses to those in other years, questions were combined to capture driving within 2 hours of smoking/vaping and/or within 4 hours of ingesting cannabis.
