This comment begs to ask the question, "What vaping is good for you?"
The simple fact is humans weren't designed to have fluid/moisture in their lungs, post birth. The two incidences I can think of where they do are labeled, pneumonia and drowning. To the best of my knowledge these are both conditions that no one would label as beneficial. Common sense and simple biology should tell us that vaping will have negative effects on our health, period. With or with out the addition of any other chemical.
Vaping is simply another delivery system to introduce nicotine or other substances into the blood stream. Nicotine has no beneficial qualities, it is just another substance humans use to alter their state, but society hasn't deemed hazardous enough to ban, like alcohol. Addicts are going to utilize whatever is available to deliver the vice of choice. The industry could care less what the long term effects are. They have already had the accountants research the projected profits, and they have ascertained they will outweigh the costs of the law suits down the road. If you don't believe me, just look at the Tobacco Industry. Their product is proven deadly and they are still going. The whole reason the Vaping Industry even exists is that the public was becoming educated about the dangers of smoking and it was starting to impact the Tobacco Industries bottom line. Cigarette smoking was on the decline. They needed a new way to hook people on nicotine. The trick was they needed something the kids would find cool, the government wouldn't know how to regulate, and could be perceived as or believed to be, benign. I must say, it is impressive how well they nailed it.
Regardless of which way the news report on Vaping, anyone who thinks the end result of doing so will be of no consequence, is ignoring biology and fooling themselves.
