People With Both Cannabis and Alcohol Problems Had the Highest Rates of Suicidal Thinking During the Pandemic

In a Saskatchewan survey during COVID-19, suicidal ideation was most common among those with both problematic cannabis and alcohol use (25.8%), and younger adults (16-34) were most likely to experience all three problems together.

What This Study Found

Suicidal ideation prevalence was highest among dual substance users (25.8%) compared to alcohol-only (23.2%) or cannabis-only (18.7%) problematic use. Younger age (16-34), changes in other substance use, pre-existing mental health diagnoses, and low resilience were independent predictors. LGBTQIA2S+ identity and pandemic stress predicted problematic cannabis use specifically.

Key Numbers

666 respondents; 25.8% suicidal ideation among dual cannabis/alcohol problem users; 23.2% alcohol-only; 18.7% cannabis-only; 16-34 year-olds most likely to experience all three; LGBTQIA2S+ identity associated with problematic cannabis use

How They Did This

Cross-sectional analysis of 666 Saskatchewan residents aged 16+ from March 2022 data collection by MHCC-CCSA. Trivariate probit regression modeled the joint occurrence of suicidal ideation, problematic alcohol use, and problematic cannabis use simultaneously.

Why This Research Matters

The pandemic highlighted the intersection of mental health and substance use crises. Understanding that these problems cluster together, especially in younger people and those with pre-existing conditions, can guide targeted intervention during future public health emergencies.

The Bigger Picture

This study reinforces that suicidal ideation, alcohol problems, and cannabis problems frequently co-occur and share risk factors. Treating them as separate issues may miss the interconnected nature of these crises, especially during periods of societal stress.

What This Study Doesn't Tell Us

Cross-sectional design during a pandemic may not reflect typical patterns. Self-reported measures may underestimate substance problems and suicidality. Single Canadian province limits generalizability. Cannot establish causal relationships between variables.

Questions This Raises

  • ?Did the pandemic create new co-occurrence patterns or amplify existing ones?
  • ?Would integrated substance use and mental health interventions reduce all three outcomes?
  • ?How do these patterns compare post-pandemic?

Frequently Asked Questions

Does using cannabis and alcohol together increase suicide risk?

This study found the highest rates of suicidal thinking (25.8%) among people with both cannabis and alcohol problems. However, it cannot prove the substances caused the suicidal ideation, as underlying factors like mental health conditions likely contribute to both.

Who was most at risk during the pandemic?

Younger adults (16-34), people with pre-existing mental health diagnoses, those with low resilience, and individuals who changed their substance use patterns during the pandemic were most likely to experience suicidal ideation alongside substance problems.
