A new study has found changes in cardiovascular function after vaping e-liquids, despite the fact that the liquids tested did not even contain nicotine.
The study, published on Tuesday in the journal "Radiology", concluded that vaping can "temporarily impact blood vessel function in healthy people." Researchers said they found "changes in blood flow within the femoral artery in the leg after just one use."
The researchers said they were unable to determine the chemical that might be responsible for the changes they observed.
The study is the most recent addition to a proliferation of research aiming to measure the impact of e-cigarettes on the heart, blood vessels, lungs and brain. But experts say the research remains in its early stages, often taking place in the lab or in animals.
