A recent study conducted by scientists from the University of Calgary in Canada, in collaboration with colleagues from the United States, has shed light on the potential health risks associated with cannabis addiction. The study, which analyzed data from 60,000 Canadians over a span of eight years, found that individuals addicted to cannabis have a 60% higher risk of developing heart diseases. These findings come at a time when marijuana legalization is sweeping across various countries, and the drug is used by over 200 million people worldwide.
The University of Calgary, where the study originated, is a renowned institution situated in Southern Alberta. It is a hub for various kinds of research, including medical studies. While the university’s website did not provide specific details about this particular study, it is known for its Cumming School of Medicine, which could be the department where this research was conducted.

The Data Speaks
The study collected data from 60,000 Canadians, half of whom were diagnosed with cannabis use disorder. The results were then compared with the other half who did not use marijuana. Between 2012 and 2019, 721 patients addicted to cannabis were found to have developed heart-related issues. These ranged from seizures and arrhythmias to peripheral vascular diseases. This data corroborates a similar study published in the journal Addiction, which also highlighted the increased cardiovascular risks associated with cannabis addiction.

The Underlying Mechanism
While the exact mechanism through which cannabis affects the heart remains unclear, scientists speculate that it may be related to the activation of the endogenous cannabinoid system. This system comprises endocannabinoids, their receptors, and complex downstream signaling pathways. Once cannabinoids enter the bloodstream, they activate G protein-coupled cannabinoid receptors, leading to a series of reactions such as tachycardia, vasospasm, and platelet accumulation.

The Global Context
The implications of these findings are far-reaching, especially considering the increasing legalization and use of marijuana worldwide. Over 200 million individuals globally use cannabis, and 27-34% of them are affected by cannabis use disorder. The absence of treatments and limited access to behavioral interventions make this a significant public health concern. Source: Herald-Review.com
A Word of Caution
While the study provides valuable insights into the potential risks of cannabis use, it is essential to note that the research is still in its nascent stages. Further studies are required to understand the long-term effects and the exact mechanisms through which cannabis impacts cardiovascular health. Nevertheless, these findings serve as a cautionary tale for both medical practitioners and the general public, urging them to weigh the pros and cons before indulging in cannabis use.
The study from the University of Calgary and its American collaborators adds a critical dimension to our understanding of cannabis and its potential health risks. As marijuana continues to gain legal status and social acceptance, such research is invaluable for informing public health policies and individual choices.
