> three- to five-fold

So from almost zero percent to still almost zero percent.

well smoking tobacco only increases your chances ~20 fold for lung cancer, so still almost zero to still almost zero?

I could be wrong but I think the other effects of smoking are worse for quality of life as you age and are way more common than cancer.

I knew a lot of lifelong smokers. I believe only one got lung cancer, didn’t die of it, but all that lived long enough had oxygen tanks, at least periodically, later in their lives.

Smoking anything carries an increased risk of developing COPD. It’s not super important what plant it is.

> 10% of smokers develop lung cancer.

< 10% of all lung cancers are found in non smokers.

The risk isn't really comparable with smoking tobacco.

The rates that are non-zero but small are chance of being diagnosed over some time period, usually one year.

What matters more is lifetime risk though, which adds up. We’re probably talking going from a single digit percentage chance to something three to five times that.
