Study Finds Vaping Immediately Impairs Blood Flow and Oxygen Levels

New research reveals significant vascular and oxygen uptake effects from e-cigarette use, even without nicotine.

A study conducted at the University of Pennsylvania shows vaping causes immediate reductions in blood flow velocity and oxygen levels in the body.
The research involved 31 smokers and vapers, aged 21 to 49, and compared their results to 10 non-smokers and non-vapers.
Both nicotine and non-nicotine e-cigarettes significantly impaired vascular function, with nicotine-containing vapes showing the greatest impact.
Researchers observed decreased venous oxygen saturation, suggesting reduced oxygen uptake by the lungs after vaping.
Experts warn that the findings highlight potential long-term risks, including vascular disease, and recommend avoiding both smoking and vaping.
