A recent large-scale study has revealed surprising findings: cannabis use may be worse for heart health than cocaine. While cannabis is widely used today for relaxation, pain relief, and even medical treatment, researchers warn about its serious risks to the heart.
Cannabis Use Linked to Higher Heart Risks
The study, published in the journal Heart, analyzed data from over 432 million people worldwide. It found that cannabis users face a 29% higher chance of heart attack, a 20% higher risk of stroke, and more than double the risk of dying from heart disease compared to non-users.
Stronger Cannabis, Greater Danger
Cannabis products today contain much higher levels of THC, the active chemical that affects the brain and body. This increase in potency raises concerns about stronger effects on the heart. In countries like Germany and parts of the U.S., cannabis is becoming more accessible, leading to more frequent and heavier use, especially among young people.
Regular Use Increases Stroke and Heart Attack Risk
While occasional cannabis use may not pose a major risk, regular use—particularly among younger adults—significantly raises the chances of stroke and heart attacks. For example, an Australian study found weekly cannabis users were nearly five times more likely to have a stroke or mini-stroke. Similarly, young cannabis users in the U.S. were found to have a 36% higher risk of heart attack.
Cannabis Outperforms Cocaine as a Heart Risk
One striking finding from a French hospital study showed cannabis was a stronger predictor of heart attacks than cocaine, even after accounting for tobacco and other drug use. This challenges common perceptions about cannabis being a “safer” drug.
Higher Death Rates from Heart Disease
The research also showed that cannabis users who suffered heart attacks were more likely to die from heart-related causes. A UK study found that heavy cannabis use increased heart-related death risk especially among women.
Medical Benefits Do Exist, But Caution Is Needed
Despite these risks, cannabis does have proven medical uses. It helps manage chronic pain, eases chemotherapy side effects, and reduces seizures in some epilepsy patients. However, experts warn that the growing strength and variety of cannabis products require stricter health warnings.
Experts Call for Tobacco-Style Warnings on Cannabis
Health experts recommend treating cannabis like tobacco: not criminalizing it, but discouraging use and protecting people from secondhand exposure. They stress the need for more research on how different cannabis components affect heart health.
