'It is my understanding that exhaled e-cigarette vapor consists of very small particles of water, propylene glycol and glycerin and flavor chemicals, not droplets of saliva,' he said.
Dr Benowitz's comments follow reports that inhaling secondhand vapour is a way of catching COVID-19.
'We're all used to walking down the street now and it's one cloud followed by another cloud, followed by another cloud.
'Blowing vapour out is as good as someone spitting in your face.
'The vapour itself contains respiratory droplets including saliva, mucus and bacteria and when it's blown out, it travels for a long distance and hangs in the air at head height.
that the large respiratory droplets we produce when we breathe, talk, cough or sneeze are our number one enemy.
But coronavirus can also spread by the much smaller aerosol particles we produce during exhalatory activities, such as when we cough or sing, and these can remain suspended in the air for hours and travel up to four metres.
The original statement by the WHO that [COVID-19] is [only] spread by droplets and contact is not based on any evidence at all, they just pulled that out of a hat and said it, and then anyone who tried to say any differently was held to a different standard of proof.
A US government lab study confirmed that vitamin E acetate is likely behind a wave of vaping illnesses and deaths. Most of the cases involved black market marijuana vaping products.
As the world argues about the safety of electronic cigarettes, it’s clear that we need to place a greater emphasis on scientific research. Interestingly, there have been studies done prior to the birth of ecigs that give us a clue as to how vaping impacts the human body. A perfect example of this is a study conducted by Dr. Oswald Hope Robertson of the University of Chicago’s Billings Hospital in 1942. Dr. Robertson studied how the inhalation of propylene glycol impacted laboratory mice.
Propylene glycol is one of the primary ingredients in e-liquid, but even before it was used to make electronic cigarettes, Dr. Robertson was testing its effects by inhalation. He suspected that this powerful ingredient could potentially be helpful for treating respiratory diseases, influenza, and even pneumonia.
To test his theory, he placed groups of mice into two chambers. In the first chamber, he sprayed the air with propylene glycol and then the flu virus. In the second chamber, he sprayed only the flu virus. Surprisingly, all of the mice in the chamber sprayed with propylene glycol survived, whereas the mice exposed only to the flu virus died.
Dr. Robertson concluded, “The propylene glycol itself was a potent germicide. One part of glycol in 2,000,000 parts of air would – within a few seconds – kill concentrations of air-suspended pneumococci, streptococci, and other bacteria numbering millions to the cubic foot.”
So what is this powerful substance known as propylene glycol? It is essentially a synthetic liquid that absorbs water. Today, we use PG in many cosmetic, food, and pharmaceutical products. It is also used in fog machines and even to generate smoke for fire fighter trainings. The FDA classifies PG as a food and drug additive that is “generally recognized as safe”. It is clear, colorless, and has no taste or odor.
Electronic cigarettes utilize propylene glycol in the e-liquid. When it heats up, it turns into a vapor that the smoker inhales. Looking back at Dr. Robertson’s study from 1942, we see that PG might offer benefits apart from just smoking cessation. It seems that PG could even help keep us healthy and protect against the spread of viruses like the flu.

Also according to french researchers smokers were 80 percent less likely to catch COVID-19 than non-smokers of the same age and sex.

The study only says that smokers are less likely to get it but when they do get it most likely a higher risk of complications/worse outcome.
Also in China 80%! of the population smokes...

nicotine and PG are both antimicrobial and I have a hunch that it kills corona, so I think we are doing everyone a favor.

So no people didn't die because of vaping but because of people where vaping marijuana juice with vitamine e (which is very bad for you lungs).

Also it could be that with vaping you are even more protected against Corona:
