I wonder if there is the dose too. Pack a day is what 20 or 25 smoking sessions, I don't think too many marijuana users are that frequent.

Vapes are at all time high though.

Have any studies linked vapes in vivo to cancer yet? Nicotine itself does not appear to be carcinogenic.

Too early for any of the official things to say. We’re still in the “9/10 doctors say smoking is good for your waistline” phase.

Call me crazy, but I happen to believe the best thing for my lungs is plain old air.

That study doesn’t say that the vaping itself has lower associated health risks, just that it doesn’t have the same, known risks as smoking. It could very easily have more risks that are as of yet unknown, because studies haven’t been around enough to tell. If I had to pick from the two, I’d go with smoking, because at least then there’s hundreds/thousands of years of knowledge about the long term effects.

Put simply, I’ve met old dudes who have been rolling their own grits for half a century or more, and still have the physical capacity to bushwhack up mountains with me. I’ve never met a fit old vaper.

(as an aside, rolling your own is the real best approach IMO: no disgusting cigarette butts littered everywhere, and there’s a mindfulness associated with the process that provides a limiting factor)

I'm still trying to find the memo I missed that made it socially acceptable for folks to vape indoors. Come into my house and vape around my kids? Really?

people think it is more surreptitious than it is

Who is walking in to your house and letting off clouds? Generally you ask, or if your host is a vaper wait to see if they do first.

For all other public indoor settings its already illegal.

I've had to tell off at least 2 people who were vaping in the climbing gym in London.

My dad is 98. Started smoking when he was 9. At one point he was smoking 70 a day. He worked as a fireman on steam trains when he was in his 20s. He lived in London during the 1950s when the smog was so bad you could walk into a lamp post when the lamp above was lit. People warned their houses with coal, powered the city with coal, burnt their trash in the back garden and smoked a lot. Sure, the average lifespan was low. But he only quit smoking in the 1980s. I'm not saying that smoking isn't bad, but if there is a sudden rise in cancer among young people, it's not that simple. The number of smokers today is tiny. In the UK, smoking rates among young adults (aged 18-24) have significantly declined over the last few decades. In 2011, about 25.7% of this age group smoked, but by 2021, that number had fallen to 13.2%. I don't have stats from the 50s but according to my father he didn't know anyone who didn't smoke.

Self-explanatory:
