Connected Study Reveals Heart Disease Risk with Cannabis Consumption
In a groundbreaking study published in the prestigious journal Heart, researchers have found a significant link between regular cannabis use and the increased risk of heart attacks and strokes. The study, which analysed health data from over 200 million adults aged 19 to 59, suggests that cannabis users face a substantially elevated risk of cardiovascular problems compared to non-users [1][2][3][4].
Key findings from the study include:
- Cannabis users under the age of 50 have up to a sixfold increased risk of heart attack and a fourfold increased risk of stroke [1].
- Chronic cannabis smoking and the use of THC-containing edibles contribute to endothelial dysfunction, impairing blood vessel function and potentially causing heart attacks [1][4].
- The analysis of pooled data found that cannabis use doubled the risk of death from cardiovascular disease [2][3].
- Observational studies show that cannabis users have a 20-29% higher risk of stroke and heart attack, with harmful effects seen in both smoked and edible cannabis forms [4].
- The increased potency of cannabis over the past few decades (THC rising from ~4% in 1995 to over 16% recently) may amplify cardiovascular risks [3].
- Cannabis use has also been linked to irregular heart rhythms such as atrial fibrillation, which raises the risk of stroke and heart failure [3].
While the study does not definitively prove or explain the connection between cannabis use and cardiovascular events, it does highlight a notable and underrecognized risk factor for heart disease. Experts recommend that clinicians screen for cannabis use and counsel patients about its potential heart-related harms, especially for young users and those with preexisting heart conditions [1][2].
It's important to note that cannabis, commonly known as marijuana, is classified as a Schedule I substance under the Controlled Substances Act at the federal level. However, loosening of restrictions in the United States and other nations is providing more data from national surveys, epidemiological studies, and clinical research.
As the use of cannabis continues to rise worldwide, it's crucial to consider the potential risks before using it. Discussing cannabis use with your healthcare provider is advised, especially for older adults and those with existing heart conditions. Further research is needed to understand the long-term health effects of cannabis use.

- The study published in Heart journal reveals a strong link between chronic cannabis use and an increased risk of heart attacks and strokes, particularly in users under the age of 50.
- Research indicates that cannabis smoking and THC-containing edibles can lead to endothelial dysfunction, thus potentially causing cardiovascular problems.
- Findings from the study suggest that cannabis use may double the risk of death from cardiovascular disease and contribute to irregular heart rhythms like atrial fibrillation.
- Considering the potential link between cannabis use and cardiovascular events, it's advisable for individuals with pre-existing heart conditions and older adults to discuss cannabis use with their healthcare providers and be aware of the potential heart-related risks.
