Electronic Cig's

I'm not quite sure how David Letterman fits into this subject, but I will offer the information I found on the david letterman electronic cigarette  and let you decide.  It's the new way to smoke and it gives you the freedom of offending other people around you.  I read that it comes in different flavors and lasts much longer than you would expect something like this to last.  The price seems affordable, especially when you consider the price for a pack of real cigarettes.
