Research Highlights:

• As more people across the U.S. use marijuana for medical and recreational reasons, two new studies suggest its regular intake may damage heart and brain health.
• In one study, daily use of marijuana raised the risk of developing heart failure by about one-third, even after considering other factors, compared to people who reported never using marijuana.
• In a second study, older people with any combination of Type 2 diabetes, high blood pressure and high cholesterol who used marijuana, significantly increased their risk for a major acute heart or brain event while hospitalized, compared to those who reported not using marijuana.
