Cannabis use has become increasingly common in Canada, with many viewing it as a safe or even beneficial substance. However, a recent study conducted by the Bruyère Research Institute, University of Ottawa, The Ottawa Hospital, and ICES challenges this perception. The study examines the potential risks associated with heavy cannabis use and its link to anxiety disorders.
Methodology
Published in eClinicalMedicine, this extensive study analyzed health records from over 12 million individuals in Ontario, Canada, covering the period from 2008 to 2019. Researchers focused on individuals who visited the emergency department (ED) due to cannabis use, comparing their outcomes with those of the general population who had no prior diagnosis or treatment for anxiety.

Key Findings and Statistics
Increased Risk of Anxiety Disorders
The study found that 27.5% of individuals who visited the ED for cannabis use were diagnosed with a new anxiety disorder within three years. This rate is nearly four times higher than the 5.6% incidence observed in the general population, indicating a significant correlation between cannabis use and anxiety disorders.
Severity of Anxiety Among Cannabis Users
Additionally, 12.3% of cannabis users required hospital or ED care for severe anxiety, compared to just 1.2% in the general population. This finding highlights the potential severity of anxiety symptoms among cannabis users.
Demographic Insights
The research identified young adults (ages 10–24) and men as the demographics most at risk of developing anxiety disorders related to cannabis use. Notably, heavy users whose ED visits were primarily due to cannabis use faced a 9.4 times higher risk of needing hospital care for anxiety.

Implications of the Study
Understanding the Causality Dilemma
A major question arising from the study is whether cannabis use causes anxiety disorders or if individuals with anxiety are more likely to use cannabis for self-medication. While the study does not provide a definitive answer, it suggests that cannabis use could exacerbate anxiety rather than alleviate it.
Health Misconceptions and Risks
The study challenges the common misconception that cannabis is inherently safe or beneficial for health. The authors caution against using cannabis to manage anxiety symptoms, as it may delay appropriate medical treatment and potentially worsen anxiety over time.
