It's about harm reduction but that isn't sensationalist enough so of course the news isn't going to run with that.
Yes vaping is less harmful but it's not better than smoking nothing at all. I've actually been thinking about this for the last few weeks. Everyone talks about how they should quit smoking, etc but not with vaping. I know many smokers, myself included, that talk about how they need to stop but with vapers, again myself included, never even consider quitting vaping. Lowering the niciotine, perhaps, but not quitting. We know vaping is less harmful, but there's no reports of how less harmful bearing in mind that a vape session lasts a lot longer than a normal fag.
