How THC Affects the Cardiovascular System
THC, the main psychoactive compound in cannabis, can temporarily increase heart rate and blood pressure. These changes may put extra strain on the heart, especially in people with existing cardiovascular conditions.
Can THC Cause Heart Problems
Some studies suggest that THC use may be linked to a higher risk of heart rhythm issues and, in rare cases, heart attack or stroke. The risk may be higher for older adults or those with heart disease.
What the Research Says
Research is still evolving, but health authorities note that cannabis can pose serious heart risks for vulnerable individuals. For more details, see the American Heart Association overview on cannabis and heart health.
