Not touting for illicit use, but research shows that marijuana smokers were less likely to have AFib.
3,950,392 patients were admitted with a diagnosis of HF (Heart Failure) in the United States in 2014. Among these, there were 17,755 (0.45%) cannabis users. In the matched cohort, cannabis users were less likely to have AF (19.08% vs 21.39%; AOR 0.87 [0.77 to 0.98]). In conclusion, cannabis users have lower odds of AF when compared with nonusers, which was not explained by co-morbid conditions, age, insurance type, and socioeconomic status.
