It’s all over the news: currently more than 200 mostly young people have been hospitalized with life-threatening respiratory illness.  At least one of them has died.  

 

A new study from the University of Pennsylvania shows that even vaping once without any nicotine leads to significant blood vessel lining damage.

 

The study analyzed 31 healthy non-smoking adults before and after vaping a single e-cigarette that did not contain nicotine but only the usual propylene glycol-glycerol base with tobacco flavoring added. Each participant took only 16-3-second puffs.

 

Even this limited exposure drove a 34% reduction in major arterial dilatation, a 17% reduction in peak blood flow, a 20% reduction in venous oxygenation, and a 26% reduction in blood acceleration.  The electric heating and vaporization process converts the e-cigarette liquids into toxic substances that damage blood vessels.

 

Don’t use these devices.  If you want to quit smoking and need to withdraw from nicotine, use nicotine gum or the patch.  Save your lungs, your blood vessels, and your life.
