Marijuana legalization linked to rise in heart-related hospitalizations, study finds
Researchers found legalization was linked to faster increases in atrial fibrillation, heart failure and heart attack admissions, based on more than 50 million records.
- An analysis of more than 50 million patient records published in BMJ Open on October 22 links recreational cannabis legalization in the United States to increased hospital admissions for cardiovascular disease.
- Researchers analyzed hospital data from 2012 to 2018, comparing the Western region—which began legalizing recreational sales in 2014—against other parts of the country.
- For each year of legal cannabis sales, admission rates rose by nearly 4% for heart failure, over 3% for heart attack, and over 2% for atrial fibrillation after adjusting for influential factors.
- The authors call for "a cautious approach" to legalization, arguing that findings support reclassifying cannabis as a Schedule III drug to facilitate detailed health research.
- While this observational study cannot establish direct cause and effect, the team notes that legalization is associated with more widespread cannabis use, particularly among older adults facing higher cardiovascular risks.
