Study: Marijuana usage nearly doubles risk of a heart attack


According to a study by researchers from the University of Toronto, smoking Cannabis between the ages of 18 to 44 nearly doubles the risk of a heart attack.

The Daily Mail reports that researchers came to this conclusion after studying a group of 33,000 people in that age group who had previously experienced at least one heart attack.

They found that 1.3% of Cannabis users had a heart attack, compared to only 0.8% for those who didn’t.

The study also discovered that the problem was most pronounced among those who used cannabis at least once a week.

Researchers conducted the study due to growing concerns from other studies indicating that Cannabis usage negatively affects a person’s cardiovascular system.

MRI scans conducted by London’s Queen Mary University in 2019 discovered that those smoking Cannabis had a greater likelihood of a thickening of the walls of the heart’s main pumping chamber, the left ventricle. This reduces blood flow and can increase the chances of having a stroke.
