Actually they are using them to quit smoking. It wouldn’t have said so if I didn’t mean it.
I know lots of people who switched to them, 3/4 of the smokers where I work switched. But none of them are getting away from nicotine with them, it’s just changing delivery system.
Discostu’s point is correct. Yes, people are giving up actual paper cigarettes, but with the e-cig you are still getting nicotine, mouth feel and the heat they are used to. So as Discostu said, it’s like giving up hard alcohol and switching to mixed drinks. Or beer.
