From Texas Public Radio:
Researchers asked 31 healthy adults who had never vaped or smoked cigarettes to puff on a nicotine-free electronic cigarettes 16 times. The flavor cartridges only contained tobacco flavorings and sweeteners. UT Health San Antonio pulmonologist Sandra Adams says researchers measured the blood flow in each participants’ leg before and after vaping.
“And found that the vessels, especially in their legs, but in different areas, had changes with just that little amount,” Adams says.
This is a red flag to Adams who would like to see everyone, but especially teenagers, swear off of vaping while further research is done.
“This study just shows one little snapshot of the possibility of long-term effects on the blood vessels, and then we have all the effects from all these cases around the country of adverse effects on the lungs,” Adams says.
The Centers for Disease Control and Prevention is investigating 149 cases of severe lung disease that have shown up over the last couple of weeks in 15 states, including Texas, linked to vaping.
