A study of US hospital records found that admissions for several cardiovascular conditions rose faster in the Western region after recreational cannabis sales became legal there. Researchers analyzed 50,042,564 discharge records from 2012 to 2018, comparing the West with other regions. For each year of legal sales, adjusted admission rates were just over 2% higher for atrial fibrillation, nearly 4% higher for heart failure and just over 3% higher for heart attack. The observational analysis found no statistically significant changes for the other cardiovascular outcomes studied and cannot establish cause and effect.

00:00Heart attack admissions rose just over 3% per year of legal cannabis sales in western United States.
00:06Researchers found those increases outpaced regions where recreational cannabis remained illegal.
00:12Before legalization, the western region had lower admission rates for the heart conditions studied,
00:17but that pattern changed after the region's first legal recreational cannabis sales.
00:22Researchers analyzed more than 50 million hospital discharge records, covering 2012 through 2018.
00:30Heart failure admission rates increased nearly 4% per year of legal cannabis sales.
00:35Admissions for an irregular heartbeat also rose faster after legalization.
00:39Those increases remained even after researchers accounted for factors that could influence the results.
00:45But researchers could not track illegal cannabis use or separate smoking from other methods.
00:50So whether legal recreational cannabis caused the faster rise in heart admissions remains unknown.
