(CNN)A new study is the latest to show changes in cardiovascular function after vaping e-liquids, though in this case, those liquids didn't even contain nicotine.
The study, published Tuesday in the journal Radiology, concluded that vaping temporarily impacts blood vessel function in healthy people. Using MRI scans, it found, for example, changes in blood flow within the femoral artery in the leg after just one use. The researchers couldn't determine which chemical might be responsible for the changes they observed.
