A new study reveals that vaping, even without nicotine, can significantly impair blood flow in arteries and reduce oxygen intake by the lungs. MRIs of participants showed decreased femoral artery blood flow after vaping, especially with nicotine. This adds to existing research linking vaping to cardiovascular issues, lung injuries, and the presence of thousands of unidentified chemicals in vape products.
