Marijuana smokers are more likely to develop potentially deadly heart condition if they smoke it regularly, a study suggests.
Cannabis users were 35 percent more likely to be diagnosed with atrial fibrillation within a decade compared to non-users.
Researchers said the heart condition is the most common type of treated heart arrhythmia that can lead to stroke, heart failure, and other heart-related complications. But it can often go undiagnosed because many people do not experience symptoms.
The latest study, which included data from 23 million patients also looked at the risk of heart arrhythmias among users of other drugs.
Cocaine users were 61 percent more likely to develop AF than people who did not use the drug.
People who used opiates, which can include heroin and prescription drugs, were at 74 percent increased risk of developing severe arrhythmia.
The report, authored by researchers at the University of California San Francisco, was published in the European Heart Journal.
They wrote: ‘Despite exhibiting a weaker association with incident AF than the other substances, cannabis use still exhibited an association of similar or greater magnitude to risk factors like dyslipidemia, diabetes mellitus, and chronic kidney disease.’
