Yup. They have updated studies, as late as last year, without much change in the outcome. People have been vaping for 13-14 years now too.

My point being, we have studies its less unhealthy by a huge degree, and it's also backed up by anecdotal evidence.

Whatever the case, if you are a smoker, you definitely will live longer if you switch to vaping.

How much longer compared to no smoking/vaping remains to be seen in long term.

Anecdotally: just about every smoker I know has had the effects of smoking related problems go away just after few months of vaping. No wheezing, smokers cough going away, respitory issues and sleep apnea either reduced or gone.

Ok, fair, but you're missing the blatantly obvious here:

Even if at 20 years you suddenly drop dead of vaper's lung, those first 19.99 years were significantly less unhealthy than smoking cigarettes was.

So, the longer we go without seeing long-term issues, the more extreme those issues would need to be to actually outweigh cigarette danger.
