You are forced to keep dragging on the cigarette regularly, or it goes out in the ashtray.
I think it was part of the effort to stop the dreaded "Global Warming Caused By Humans" stuff; same as stopping cow farts.
The cigarettes now start tasting like cow farts with the FSC-process, but they're still smokeable....
I make the rules in my shop; and the rule is you can smoke while you work. But never in front of a customer, and no butt's on the floor.
My own rules forced me to become a re-lighter. A common practice with me for years now. These new cigs don't go out when you want them to; I've seen several times when after one of two puffs I had to dose the smoke, then came back to it after 1 - 5 minutes. Still going! Someone who still has access to both 'fsc' and non-fsc check me on this.
And of course they do go out sometimes when you don't want, just for the annoyance factor I think. But they often produce a surprising flame up when re-lit.
I don't even want to think about how long I've been smoking. A couple days ago I ordered one of these e-cigarettes and I hoping to cut back and quit soon.
