As cannabis use becomes more mainstream—especially among adults 40 and older—many are asking: What does cannabis do to the heart? Can it help, hurt, or both? While the science is still evolving, there’s growing interest in how cannabis affects cardiovascular health.
At County Road Cannabis, we believe education is essential for responsible use. This guide offers a beginner-friendly overview of the relationship between cannabis and the heart, using insights from emerging studies and safe-use best practices.
The Basics: How Cannabis Interacts with the Cardiovascular System
Cannabis affects the endocannabinoid system, which is linked to the regulation of blood pressure, heart rate, and inflammation. Depending on the strain, dose, and method of consumption, cannabis can lead to different effects:
-
Short-term THC use may increase heart rate and dilate blood vessels, leading to lowered blood pressure in some people.
-
CBD appears to have anti-inflammatory and vasodilatory effects, which may support vascular relaxation.
-
High doses of THC, especially in edibles, have been associated with elevated heart rate and, in rare cases, heart palpitations.
These effects can vary significantly depending on the user’s age, health status, and history of cannabis use.
What the Research Says (So Far)
Current research offers both potential benefits and cautions:
-
A 2020 review in Nature suggested that CBD could offer cardiovascular protective effects, especially for those with hypertension or stress-related inflammation.
-
A 2022 study published in Journal of the American Heart Association highlighted a potential increase in cardiovascular risk from high-THC products in those with pre-existing heart conditions.
-
Other studies are exploring THC’s role in increasing heart rate—a consideration for those with arrhythmias or high blood pressure.
More research is needed, but the general takeaway is: moderation matters.
