Heart disease is the second leading cause of death in Canada, claiming more than 48,000 in a year. Additionally, about 741,800 Canadian adults over age 20 currently live with the effects of a stroke. 

In a recent meta-analysis, researchers scrutinized 24 cannabis research articles that investigated the drug’s impact on cardiovascular risk factors—cholesterol levels, obesity rates and diabetes—and cardiovascular events, including stroke and heart attack. 

Does cannabis affect heart health? We lack the data that says it does, though cannabis may be connected to a lower risk of obesity.

However, we dug up five facts about marijuana consumption, and it's relationship to cardiovascular health.


1. Low doses of THC appear to activate pro-cardiovascular health effects, while high doses seem to have a net negative.

2. High-CBD marijuana could improve the rate and speed of recovery following a heart attack and stroke. 

3. Cardiovascular events only represent 2% of all medical reports related to cannabis.

4. Synthetic cannabinoids like “K2” and “Spice” pose the highest risk of heart and health complications. Consumers are warned not to purchase this synthetic marijuana, for more than just the risk to heart health. 

5. THC increases heart rate by as much as 20-50 beats per minute to compensate for the reduction in blood pressure caused by THC.
