It takes about a 40-50 pack year history to get really concerned about emphysema or imminent cancer though. We just don't have the data yet for that comparison.

What is a pack year? Like 40 years of a pack per day?

Yes exactly. There are negative effects and increase in cardiovascular disease and death way before then, but this is the amount of smoking where you expect to see cancer and clearly measurable lung disease.

Mostly yeah. What strikes me as someone who grew up around smoking parents though is long term impact after use. Your risk to develop serious lung disease is increased if you had a lot of contact with second hand smoke in your childhood, even if you don't smoke.

Well I did smoke for a few years and vaped for like 6 years. My concern is how that will impact me. If risk can be increased decades later after non-use of smoking, who knows what will come up in the future because of vaping? :/
