Research has shown that vaping immediately impacts blood vessel function, even when using e-cigarettes without nicotine. The study, presented at the Radiological Society of North America’s annual meeting, indicated a decrease in venous oxygen saturation, suggesting reduced oxygen intake by the lungs. These findings raise concerns about the long-term health risks of vaping, including vascular disease. Notably, over 1.6 million young people in middle and high school are reported to be vaping, amplifying public health concerns.
E-cigarettes, although marketed as a safer alternative to traditional cigarettes, still expose users to harmful chemicals like lead, nickel, and formaldehyde. Dr. Marianne Nabbout, the study’s lead author, emphasized that even nicotine-free e-cigarettes have significant effects on vascular function. Using MRI scans and blood flow assessments, researchers observed a marked decrease in blood flow velocity and oxygen saturation in vapers and smokers compared to non-users. Nicotine vapers showed the most significant vascular impairment, but even non-nicotine vapers experienced notable effects.
Good vascular function is essential for efficient blood circulation and oxygen delivery. Impaired function, as seen in the study, could lead to serious conditions like blood clots, high blood pressure, and strokes. The researchers found decreased lung oxygen intake in all vapers, regardless of nicotine content. These findings are expected to inform regulatory decisions as the FDA evaluates which vaping products should remain on the market. Although some e-cigarettes have been authorized, none are approved as harm-reduction devices.
The study also challenges the notion that e-cigarettes are effective tools for smoking cessation. Contrary to manufacturer claims, evidence suggests e-cigarettes do not help people quit smoking. Dr. Albert Rizzo from the American Lung Association noted that both nicotine and non-nicotine vapes cause inflammation that can affect vascular and respiratory health. This inflammation, similar to that caused by air pollution, may lead to increased risks of heart attacks and strokes over time.
Experts are particularly concerned about the appeal of flavored vaping products to young people, potentially exposing them to harmful health effects early in life. The research underscores the urgent need for greater regulation and public awareness of vaping risks. With the long-term effects of vaping still uncertain, studies like this highlight immediate health impacts, signaling the need for continued investigation and policy action to protect public health.
