All types of smoking/vaping cut blood flow in the thigh artery, which feeds the lower body. Nicotine vapes were worst, then no-nicotine ones.
Even without nicotine, vaping cut vein oxygen. This means less oxygen, bad for the body. The lead author, Dr. Marianna Nabbout, said, “This shows smoking/vaping’s quick harm. Long-term use could mean vascular disease.” Quit now to avoid risks.
Vaping also has other health issues. Chemicals like formaldehyde and acrolein in vape vapor can irritate and harm lungs. Metals like lead and nickel from the device can build up, causing nerve and breathing problems. Some get EVALI, a serious lung injury, which can be deadly.
