Recent research suggests that cannabis might not offer relaxation for everyone, as a significant percentage of individuals seeking emergency treatment for cannabis use end up developing new anxiety disorders within three years.
The study, conducted by a team of researchers from Canada and published in the journal eClinical Medicine, is the largest of its kind investigating the link between cannabis use and anxiety. Analyzing data from over 12 million residents of Ontario, Canada, between 2008 and 2019, the researchers identified a notable trend among individuals seeking emergency care for cannabis-related issues.
Led by Dr. Daniel Myran, a Canada Research Chair in social accountability at the University of Ottawa, the study found that those presenting at emergency departments for cannabis use were substantially more likely to develop new anxiety disorders compared to the general population. Even after adjusting for social factors and other mental health diagnoses, the risk was nearly four times higher.
Furthermore, among individuals already diagnosed with anxiety disorders, those who sought emergency care for cannabis use faced a significantly increased risk of hospitalization or additional emergency visits for anxiety within three years. This elevated risk persisted even after accounting for other mental health diagnoses and social factors.
The research also highlighted that individuals across various demographics, including age and gender, were at heightened risk of developing new anxiety disorders after seeking emergency treatment for cannabis use. Notably, men and younger adults appeared to be particularly susceptible to this risk.
While debates continue regarding whether cannabis directly causes anxiety or if individuals use it to cope with existing anxiety, the findings of this study suggest that cannabis may exacerbate anxiety symptoms. The researchers cautioned against heavy cannabis use, warning that it could potentially delay other evidence-based treatments for anxiety and worsen symptoms.
Experts like Daniele Piomelli, PhD, director of the UC Irvine Center for the Study of Cannabis, emphasized the variability of cannabis effects depending on factors such as dosage and individual experience with the drug. Piomelli underscored the dual nature of cannabis, which can have both anti-anxiety and pro-anxiety effects.
Ashley Murry, chief clinical officer of Sana Lake Recovery Center in Missouri, echoed the importance of approaching cannabis use for anxiety management with caution. While acknowledging the potential anti-anxiety properties of CBD, Murry warned about the potential of THC, the psychoactive component of cannabis, to exacerbate anxiety symptoms.
Murry advised individuals, especially those with pre-existing anxiety disorders, to seek guidance from healthcare professionals before using cannabis, as it could lead to dependence and adverse effects.
