It's certainly safe enough that the NHS is using vaping to get people off smoking

Must be healthy then! …me goes to switch from heroin to fentanyl

It’s safer but not as much as not smoking.

Same way chemo cures some cancer but is pretty damaging overall. But when the alternative is death, anything else is better.

PSA: Don’t start vaping if you don’t smoke, it’s lame. Don’t start smoking either, you’ll regret the health issues, earlier death, and money wasted.

So not like my take when I see a pack of Tim Tams with a half-star health rating.. "Hey these things are a little healthy, looks like you need to eat a lot to get any benefit though"

Smoking 10 cigarettes a day is objectively healthier than smoking 20 a day. I'm sure any doctor would recommend the former to someone having the latter as a habit if that would be a successful step to stopping altogether. It doesn't make it something you would recommend for a healthy lifestyle.

I would estimate vaping to be about 1% as harmful as a pack a day smoking habit.
