Vaping, often marketed as a safer alternative to smoking, may not be as harmless as once thought. A recent study by the Radiological Society of North America (RSNA) has uncovered alarming effects on vascular function occurring within seconds of inhaling from an electronic cigarette.
How Vaping Affects Your Blood Flow
The study, led by Dr. Marianne Nabbout at the University of Arkansas for Medical Sciences, evaluated the vascular impacts of vaping on 31 healthy individuals aged 21 to 49. Participants underwent MRI scans before and after inhaling tobacco smoke, nicotine-containing vape aerosols, and vape aerosols without nicotine.
The results revealed a significant decrease in blood flow velocity in the superficial femoral artery—the primary artery supplying oxygenated blood to the lower body—immediately after vaping. Even nicotine-free vapes caused reduced venous oxygen saturation, indicating a diminished ability of the lungs to absorb oxygen.
These findings challenge the perception that vaping is a benign alternative. Dr. Nabbout explained, “While e-cigarettes contain fewer chemicals than tobacco smoke, they still pose measurable risks to vascular health.”
The Bigger Picture
As vaping grows in popularity, particularly among younger demographics, concerns about its long-term health impacts are mounting. In the UK, the government plans to ban disposable vapes by 2025, coupled with a tax increase on refillable vape liquids, as part of a broader effort to curb youth vaping.
While vaping lacks the combustion process of traditional smoking, this study demonstrates that both nicotine and non-nicotine aerosols can impair blood circulation. Experts urge caution, noting that the immediate vascular changes could contribute to long-term cardiovascular risks.
Dr. Nabbout emphasized, “Refraining from smoking and vaping is always recommended. Science must guide public health regulations to mitigate these risks.”
This research serves as a stark reminder: vaping is not risk-free. As its use continues to rise, so does the need for informed choices and effective regulation.
