In addition, people should not add any substance to e-cigarette or vaping products that are not intended by the manufacturer, including products purchased through retail establishments.
"It is crucial to emphasize that e-cigarettes are not safe, just less harmful than tobacco cigarettes when it comes to vascular health", George said.

Vaping and e-cigarettes are the same thing.
And they warned that vaping is not safe, merely "less harmful" than smoking.
But for "chronic" tobacco smokers - those who have smoked at least 15 cigarettes a day for two years - switching resulted in an nearly immediate benefit.
He said: "The crunch is that is what this study shows is a change in function, so that you change the ability of the vessel to dilate, but what long-term smoking does may have actually changed the structure of the vessel so however much you stop smoking, it will never get back to normal because it's changed permanently".
