Ont. study shows cannabis use may increase the risk of developing anxiety disorder, worsen existing anxiety

The study found 27.5% of people who visited an ER for cannabis use developed an anxiety disorder for the first time within three years. In comparison, 5.6% of the general population sought assistance for anxiety in an ER or outpatient setting over three years. Researchers also found that 12.3% of cannabis users with pre-existing anxiety but no record of hospitalization visited an ER or were admitted to hospital because their anxiety symptoms worsened. While people of all ages who had a cannabis-related ER visit were at higher risk of developing new anxiety disorders, the risk was particularly great for males up to age 24. The findings suggest a need for more conversations about potential links between cannabis use and mental health, especially for people who are vulnerable to worsening anxiety or developing it from heavy use.
