While there are probably as yet unknown effects of vaping that might prove this otherwise, at this pint all the data says that by virtue of the fact that a person who is vaping is not taking smoke and tar into their lungs, vaping is not NEARLY as bad for a perosn as smoking.

There is basically no science behind the claims that vaping si worse than smoking.

Not advocating for either, but it looks like there is much misinformation around vaping.
