Cannabis Can Trigger Heart Attacks, Arrhythmias, and Rare Cardiovascular Events
A cardiology review summarized evidence that cannabis can trigger acute heart attacks in otherwise healthy young people, promote atherosclerosis, cause arrhythmias, and lead to Takotsubo cardiomyopathy and cannabis arteritis.
Quick Facts
What This Study Found
Cannabis has been linked to acute myocardial infarction in young, otherwise healthy individuals; atherogenesis acceleration; cardiac arrhythmias; Takotsubo (stress) cardiomyopathy; and cannabis arteritis. The only definitive treatment for these conditions is complete abstinence.
Key Numbers
The review described specific cardiovascular conditions: acute MI, atherogenesis, arrhythmia, Takotsubo cardiomyopathy, and cannabis arteritis. Complete abstinence was identified as the definitive treatment across conditions.
How They Did This
Narrative review examining the long-term cardiovascular effects of THC, covering pathophysiology, clinical features, and management of cannabis-related cardiovascular conditions.
Why This Research Matters
Cannabis is often perceived as cardiovascularly benign, especially compared to tobacco. This review highlights that THC can cause serious and potentially life-threatening cardiovascular events, particularly in young users who might not otherwise be at cardiac risk.
The Bigger Picture
As cannabis use becomes more mainstream, cardiologists are seeing more cannabis-related cardiovascular events. The fact that these can occur in young, healthy individuals without traditional cardiac risk factors is particularly concerning and underrecognized.
What This Study Doesn't Tell Us
Narrative review format means no systematic search or quality assessment. Many of the cardiovascular associations come from case reports and case series rather than large epidemiological studies. The relative risk compared to non-users is not well quantified.
Questions This Raises
- ?What is the dose-response relationship between cannabis use frequency and cardiovascular risk?
- ?Are CBD-only products associated with the same cardiovascular risks?
- ?Should heavy cannabis users undergo cardiovascular screening?

What do these levels mean? →Frequently Asked Questions
Can cannabis cause a heart attack?
Yes. Case reports and clinical evidence have linked cannabis use to acute myocardial infarction, sometimes in young people with no other cardiac risk factors. The mechanism involves THC effects on heart rate, blood pressure, and coronary artery function.
What is cannabis arteritis?
Cannabis arteritis is a condition similar to Buerger's disease where blood vessels, particularly in the extremities, become inflamed and narrowed. It has been reported in heavy cannabis users and can lead to tissue damage if cannabis use continues.
