A team of researchers from the United States and the United Kingdom assessed health outcomes in a cohort of nearly 10 million patients hospitalized for acute myocardial infarction (AMI).
They reported, “Cannabis use was associated with lower risks of cardiogenic shock, acute ischemic stroke, cardiac arrest, PCI [percutaneous coronary intervention] use, and in-hospital mortality.”
The conclusion is consistent with those of other studies finding that heart disease victims with a history of cannabis consumption possess greater in-hospital survival rates compared to controls. Other studies have similarly reported increased in-hospital survival rates among cannabis consumers suffering from cancer, COPD, gastroparesis, pancreatitis, HIV, burn-related injuries, traumatic brain injuries, and various other types of severe trauma.
Interesting, I recall recently reading that marijuana use is worse for heart attacks.

And another study (can’t find it at the moment) that claimed that there is a noticable increase in your risk of having a heart attack while smoking.
