New research from Alberta links cardiovascular disease with cannabis use

Nov 6, 2023 | 5:00 PM

Recent research published in the journal Addiction found adult Canadians with cannabis use disorder (CUD) had a 60 per cent higher chance of developing cardiovascular disease (CVD) than those who do not have cannabis use disorder.

The study considered 60,000 adult Canadians without previous cardiovascular issues and focused on information from health databases in Alberta.

In addition to a 60 per cent higher chance of those with CUD developing cardiovascular disease, the study found people with CUD who do not currently take any prescription medications, had few medical issues and did not regularly visit health clinics have a 1.4 per cent higher risk of developing cardiovascular disease.

“The observation that individuals without co-occurring medical illness, no prescriptions, and fewer health service visits had a higher risk of first-time cardiovascular disease events is an interesting finding from our study,” said lead researcher Anees Bahji.

“However, it’s important to note that our study was observational in nature, and we did not explore the specific mechanisms behind this observation. This is an area that requires further research to better understand why certain subgroups may be at higher risk, and it may involve a combination of lifestyle factors, genetic predisposition, and other variables that were not within the scope of our study.”

Bahji also stated the reasons those with CUD are far more likely to develop cardiovascular disease can be speculated, but is not yet known.

“The specific mechanisms through which cannabis consumption may increase the risk of cardiovascular disease are an important area of ongoing research …potential factors that researchers are exploring include the acute effects of cannabis on heart rate, blood pressure, and vascular function, as well as the chronic impact of cannabis on inflammation and other cardiovascular risk factors. However, it’s essential to note that this topic is complex, and further studies are needed to elucidate the exact pathways involved,” he said.

Cannabis use disorder is classified by the Centers for Disease Control and Prevention (CDC) in the United States as an individual that is “unable to stop using marijuana, even though it’s causing health and social problems in their lives.” An emerging disorder in Canada, support for CUD can vary based on location.

CUD is treated in Alberta using a variety of options, including mental health support and therapy through addiction centers. While an essential step towards understanding increased CVD in those with CUD, further research is needed to understand the study findings.

“I’d like to emphasize the importance of balanced and evidence-based discussions surrounding the use of cannabis and its potential health implications. Our study provides valuable insights into the association between cannabis use disorder and cardiovascular disease, but further research is needed to fully understand the complexities of this relationship,” Bahji said.

“It’s crucial for individuals using cannabis, especially those with CUD, to be aware of potential health risks and to engage with healthcare providers for personalized guidance and support. Additionally, ongoing research in this field will continue to inform our understanding of these matters.”
