A recent study conducted by researchers at UC San Francisco has revealed alarming cardiovascular risks associated with chronic cannabis use, whether it is consumed through smoking or edibles. The findings, published in JAMA Cardiology on May 28, indicate that regular marijuana users exhibited significantly reduced blood vessel function comparable to that of tobacco smokers. This decreased vascular function can lead to a higher risk of heart attack, hypertension, and other cardiovascular conditions.
The study included 55 seemingly healthy individuals who were chronic users of marijuana either through smoking or consuming THC-infused edibles. These participants had been using cannabis at least three times a week for a minimum of one year, with smokers averaging 10 years of use and edible consumers averaging five years. Surprisingly, while smokers showed detrimental changes in their blood serum that were harmful to endothelial cells, edible consumers did not display these same effects.
Dr. Leila Mohammadi, the lead author of the study, and Dr. Matthew L. Springer, the senior author, noted that the mechanisms through which THC damages blood vessels differ between smoking and ingesting. While the exact reasons for these differences remain unclear, the results highlight the negative impact of smoking marijuana on vascular function.
The research raises concerns about the potential long-term cardiovascular consequences of chronic cannabis use and underscores the importance of understanding the specific risks associated with different consumption methods. Further investigations are needed to elucidate the underlying mechanisms and develop strategies to mitigate the cardiovascular risks posed by marijuana use.
For more information, the study titled “Association of Endothelial Dysfunction with Chronic Marijuana Smoking and THC-Edible Use” can be accessed in JAMA Cardiology. The University of California, San Francisco provided the research findings, shedding light on the need for increased awareness of the cardiovascular effects of cannabis consumption.
