Marijuana use does not have an association with cardiovascular disease.

Subjects were excluded if they were children (<18 years old) or had missing data for marijuana use or cardiovascular disease. Age, gender, race/ethnicity, body mass index (BMI), income, exercise, tobacco use, alcohol use, and depression were all considered as potential confounders.

Researchers told while “previous literature has shown that marijuana use has a negative impact on cardiovascular health, our study suggests that users and non-users of marijuana did not have an association with the prevalence of cardiovascular disease.”

They even went further and said “there is no link to marijuana use and an increase in cardiovascular disease. Furthermore, there may be a link between marijuana use and lowered risk of cardiovascular disease.”


Cannabis usage before and/or after exercise could boost pleasure, motivation, and performance whilst facilitating post-exercise recovery.

To prevent cardiovascular disease, regular exercise is a good habit to have, and this study from Florida International University shows the possibility that using cannabis could become an additional protection.
