What are electronic cigarettes?

[Holder]

There's been a local(meaning where I am) study that's been going on about these, apparently they're not much better for you than they're leading on, or there's a side effect triggered by switching.

BUT, there's been a snag in their research which the e-cigarette companies are coming back with, they say that 100% of their customers are ex-smokers so any damage caused is due to smoking cigarettes.

So I guess the only way to confirm or deny any effects is to see what and if something happens to people who only use these.

Personally I've not tried them before, actually I've never seen where to buy them. I might try them if I could find where to though.
