Smoking, vaping or eating marijuana is linked to a significantly higher risk of heart attack and stroke, even if a person had no existing heart conditions and did not smoke or vape tobacco, a new study found. While both daily and non-daily users had an increased risk of heart attack and stroke compared to nonusers, stroke risk rose 42% and the risk of heart attack rose 25% if cannabis was used daily, the study found. The risk climbed as marijuana use time accumulated. “Cannabis smoke is not all that different from tobacco smoke, except for the psychoactive drug: THC (tetrahydrocannabinol) vs. nicotine,” said lead study author Abra Jeffers, a data analyst at Massachusetts General Hospital in Boston who researches tobacco and smoking cessation. “Our study shows that smoking cannabis has significant cardiovascular risks, just like smoking tobacco. This is particularly important because cannabis use is increasing, and conventional tobacco use is decreasing,” Jeffers said. The study’s findings mirror other research that has found daily use of marijuana is linked to an increase in coronary heart disease, heart attack and stroke, said Robert Page II, a professor of clinical pharmacy and physical medicine at the University of Colorado Skaggs School of Pharmacy and Pharmaceutical Sciences in Aurora, Colorado. “The findings of this study have very important implications for population health and should be a call to action for all practitioners, as this study adds to the growing literature that cannabis use and cardiovascular disease may be a potentially hazardous combination,” Page said in a statement. The study, published last week in the Journal of the American Heart Association, analyzed data on 430,000 adults collected from 2016 through 2020 through the Behavioral Risk Factor Surveillance System, a national phone survey performed each year by the U.S. Centers for Disease Control and Prevention. People in the survey ranged in age from 18 to 74, with an average age of 45. Nearly 90% of adults did not use marijuana, while more than 63% had never used tobacco. Among current marijuana users, nearly 74% reported smoking as the most common form of consumption; 4% were daily users, while 7% used less than daily. Nearly 29% of daily marijuana users and 44% of non-daily users never used tobacco cigarettes. Younger adults — defined as men under 55 and women under 65 years old — who used marijuana had a 36% higher risk of coronary heart disease, heart attack and stroke regardless of whether they also used traditional tobacco products. The American Heart Association advises people to refrain from smoking or vaping any substance, including cannabis products, because of the potential harm to the heart, lungs and blood vessels.
