Temporal Changes in the Cross-Sectional Associations between Cannabis Use, Suicidal Ideation, and Depression in a Nationally Representative Sample of Canadian Adults in 2012 Compared to 2002.

ABSTRACT:

Background

With the recent legalization of nonmedical cannabis in Canada, it is important to document previous associations between cannabis use and major depressive episode and suicidal ideation, as well as the extent to which these associations have changed over time.

Methods

This study uses pooled data from the 2002 and 2012 Canadian Community Health Survey's Mental Health Component, which are repeated cross-sectional surveys of nationally representative samples of Canadians 15 to 60 years of age (n = 43,466). Binary logistic regression was performed, applying weighting and bootstrapping, to examine the association between at least monthly use of cannabis and past 12-month suicidal ideation and major depressive episode (MDE).

Results

At least monthly nonmedical cannabis use was associated with an increased odds of MDE and suicidal ideation, and both associations strengthened in 2012 compared to 2002. Canadians using cannabis at least once a month in 2012 had 1.59 (95% confidence interval [CI], 1.11 to 2.27) times the odds of experiencing suicidal ideation and 1.55 (95% CI, 1.12 to 2.13) times the odds of experiencing MDE compared to those who used cannabis at least once a month in 2002. This temporal change remained after controlling for other substance use.

Conclusions

Monthly cannabis use was consistently related to both suicidal ideation and MDE, and these associations were stronger in 2012 compared to 2002. The findings of this study provide a baseline for the association between cannabis use and suicide and depression in the Canadian population that should be reevaluated now that nonmedical cannabis has been legalized.

Project description:ObjectiveWith significant levels of mental distress reported by populations, globally, the magnitude of suicidal ideation during and beyond the COVID-19 pandemic is a central concern. The goal of this study was to quantify the extent of pandemic-related suicidal ideation in the Canadian population during the first ten months of the pandemic and identify sociodemographic and pandemic-related stressors associated with increased risk of ideation.MethodData were derived from three rounds of a mental health monitoring survey, nationally representative by age, gender, household income, and region, delivered online in May 2020, September 2020, and January 2021. Bivariate analyses were used to quantify the proportion of respondents in Canada reporting suicidal ideation by sociodemographic factors and pandemic-related stressors. Unadjusted and adjusted multivariable logistic regression was used to study the association between suicidal ideation and correlates within four pandemic-related stressor categories (financial, relationship, substance use, COVID-19 exposure).ResultsOf the 7002 respondents, 6.2% (n = 433) reported experiencing suicidal thoughts or feelings as a result of the pandemic within the two weeks prior to taking the survey. In terms of sociodemographic factors, suicidal ideation was more commonly reported among those who were not cisgender, <65 years-old, single, Indigenous, LGBT2Q+, and who experience a pre-existing mental health condition. After adjusting for sociodemographic factors, indicators across all four pandemic-related stressor categories were associated with two or more times the odds of suicidal ideation.ConclusionDisparities in COVID-19 related suicidal ideation have persisted throughout the first year of the pandemic for specific sociodemographic sub-groups and those who have faced stressors related to finances, relationships, increased substance use, and COVID-19 virus exposure. To best address these disparities and to prevent a transition from suicidal ideation to action, appropriate planning, resources, and policies are needed to ensure health and well-being for everyone.
