There is definitely, if you're enjoying the nicer taste, a tendency to puff, and puff and puff. SPecially if you're sitting in front of your computer reading 15,000 interesting posts here about things you want to try next.
On the other hand, my wife (who just WON'T switch to vaping - she wants to "quit smoking" some other way) is jealous of how I can pull my gizmo out

ohmy

take a puff, and drop it back in my pocket, satisfied for the moment. While watching TV, or while walking from the car to a restaurant, or whenever.
Do I vape more than I smoked? Yes - because I will vape in my house...
But when running about or working - it's probably less, because I don't have to "finish" anything - I just take a puff or two when I feel like it.
It's VERY common for people to "chain vape" when they first get started - learning how it works, what they like, and enjoying it more too! Most people seem to then reduce it a bit - put the thing down between puffs! But heck - if you're not overdoing the nicotine, vaping a lot isn't such a bad thing anyway, right!?
