NEW YORK CITY (CNN NEWSOURCE) — A new study shows vaping can impact blood vessel function after just one use.
In a study published in the medical journal Radiology, researchers used MRI scans to measure blood flow in the major artery that supplies blood to the legs of people using e-cigarettes. They discovered blood flow in the femoral artery changes very quickly after vaping, but reverses back to normal within a few minutes. The 31 participants in the study had never smoked or vaped before.
Scientists don’t know what substance led to the response because the liquid used in the e-cigarettes contained no nicotine. Most vaping devices contain heavy metals and chemicals that are thought to affect the heart, lungs, and brain.
Little is known about the long-term impact on vaping and most researchers believe it is not as dangerous as smoking.
