Recent research indicates regular cannabis use, including smoking and consuming THC-laced edibles, may be associated with early signs of cardiovascular disease. The study highlights potential health risks amidst the increasing legalization and consumption of cannabis in the United States.
The study, involving 55 participants, divided them into three groups: marijuana smokers, THC edible users, and non-users. Results showed that marijuana smokers experienced a 42 percent reduction in vascular function, while THC edible users faced a 56 percent reduction compared to non-users. These findings suggest that both smoking and consuming THC can lead to impaired vascular health.
Matthew Springer, a researcher involved in the study, noted that previous research on tobacco indicated chronic smokers displayed poor endothelial function. This study aimed to determine if similar effects occurred in cannabis users. The research found that both marijuana smoke and THC edibles impaired vascular health, challenging the perception that cannabis is a harmless alternative to tobacco.
A separate retrospective analysis of over 4.6 million individuals under the age of 50 found marijuana users had a more than sixfold increased risk of heart attack, a fourfold risk of ischemic stroke, and a threefold risk of cardiovascular death compared to non-users. This data reinforces concerns about the cardiovascular implications of cannabis use.
Additionally, a meta-analysis presented to the American College of Cardiology indicated that current cannabis users are 1.5 times more likely to experience a heart attack compared to non-users. While these studies demonstrate strong associations, researchers emphasize that they do not definitively establish causation between cannabis use and vascular damage or heart attacks.
Springer pointed out that the vascular function impairment correlates with the frequency of cannabis use, suggesting that higher consumption levels lead to greater negative impacts on vascular health. He urged that individuals considering or currently using cannabis should recognize the associated health risks, especially at high usage levels.
In light of these findings, researchers recommend that clinicians include questions about cannabis use in cardiovascular risk assessments. Dr. Ibrahim Kamel, a lead author of one of the studies, stated that raising awareness about the risks of cannabis consumption is crucial for public health.
Going forward, researchers are advocating for larger, long-term studies to better understand the direct effects of cannabis and THC on cardiovascular health. These future studies may inform updated guidelines and recommendations regarding safe usage levels and health risks associated with cannabis consumption.
