Victoria AdolphusA recent study presented at the annual meeting of the Radiological Society of North America (RSNA) has uncovered the alarming vascular risks associated with vaping. The research reveals that both cigarette and e-cigarette use significantly impairs vascular function, even in the absence of nicotine.
The Immediate Impact of Smoking and Vaping on Vascular Function
The study, conducted at the University of Pennsylvania, involved 31 healthy smokers and vapers aged 21-49. Participants underwent MRI exams before and after smoking or vaping episodes, including tobacco cigarettes, e-cigarettes with nicotine, and e-cigarettes without nicotine.
The results showed a significant decrease in resting blood flow velocity in the superficial femoral artery after inhalation of each type of vaping or smoking. The decrease in vascular function was most pronounced after inhalation of e-cigarettes containing nicotine.
The Alarming Consequences of Vaping on Vascular Health
The study’s findings highlight the immediate negative impact of vaping on blood flow and oxygen uptake. This raises concerns about the long-term vascular health risks associated with vaping.
According to Dr. Marianne Nabbout, lead author of the study, “This study serves to highlight the acute effects smoking and vaping can have on a multitude of vascular beds in the human body.”
The Take-Home Message: Vaping is Not Safe
The study’s findings emphasize the importance of avoiding both smoking and vaping for better health. As Dr. Nabbout notes, “Refraining from smoking and vaping is always recommended.”
The research project was supported by the National Institutes of Health. As the study’s authors conclude, “Ultimately, we are relying on science to help guide the regulation of such products in favor of public health.”
