Maybe they went back to smoking cigs because the fake cigarette didn't taste like their brand.
I quit a long time ago, but the only cigarette that could ever tempt me would be a Parliament. Make that a Parliament 100. I remember a 7-11 not carrying the 100's and I'd buy the regulars. yuck and ptu ptu ptu....
To use this to quit smoking would be ok with me, it would reinforce it wasn't a parliament, and I'd just end up giving them up altogether.
anyway, I'm for anything that might get a person to quit those stinking cancer sticks.
