Cannabis use linked to higher stroke and cardiovascular disease risk

Key Points:

• A study of nearly 450,000 American adults found that cannabis use is linked to an increased risk of stroke and cardiovascular disease, with both casual and heavy users showing higher odds compared to non-users.
• Low-frequency cannabis users (1-5 days per month) had 23% higher odds of cardiovascular disease and 40% higher odds of stroke, while heavy users (16-30 days per month) had 21% higher odds of cardiovascular disease and 25% higher odds of stroke.
• The study found no significant link between cannabis use and heart attacks, and the method of consumption (smoking, vaping, edibles) did not affect the cardiovascular risk.
• Researchers cautioned that the study is observational and cannot prove causation, with limitations including reliance on self-reported data and lack of information on THC potency or dosage.
• Experts advise patients not to stop prescribed cardiovascular medications based on this preliminary study but recommend that doctors routinely inquire about cannabis use similar to questions about tobacco and alcohol.
