While that does vaguely gesture at an increased nicotine consumption, it's pretty meaningless without the corresponding consumption rates. My gut suspects the average smoker goes through a pack of cigarettes a lot faster than the typical vaper goes through a rechargeable disposable vape.

Pack a day is considered heavy smoking.

I go through those rechargeable ones in a week. That's pretty common I think for how addictive they are. https://www.reddit.com/r/Vaping/comments/1i9mva3/how_long_do...

Before the disposables were a thing most juices were either 0.3% or 0.6%

This is 100% big tobacco trying to get people hooked
