10ml is good for a week or so. That's at 10% nicotine strength. 125ml of nicotine fluid is under $10 retail. So you go from a pack a day at $3 a pack (plus $3-4 taxes depending on the state - but Marlboro sees none of that) to $10 across four months. Sure, you can buy more expensive fluid, but we're still in the land of ridiculous reduction in expense. Nope, they can take the pure shit leaves. Even the $40 ones fry after six months. And people lose them. Dont the real benefice come from the recharge ?
Even the chemist need the sweet sweet tobacco leaves.
The electronic-cig ? You need one every other years.
But from the get go, I dont get the argument: There is no taboo abour e-cig, everyone want them, buy them, and talk about how cool and safe they are.
