Is The RIVA E-Cigarette a Safe Alternative?

What is the RIVA E-Cigarette?
     E-Cigarettes are smoke-less, electronic cigarettes and they are growing in popularity as a safe alternative to tobacco-cigarettes.  A few people at the office have these, and they "smoke" them in the work-place between calls.  Sometimes they smell like scented candles, but they can also be odorless.  There are many benefits in choosing to go the e-cig route:

1. No smoke and no fire (smoke safely in the car and around flammable substances) 
2. No carcinogens (as opposed to the 40+ cancer-causing substances found when burning tobacco)
3. No mess, no cigarette butts, no ashes, no ashtrays
4. No restriction on where you can "smoke".  These kinds of cigarettes are allowed in bars and restaurants that ban cigarette smoke.
5. No tar, no stale after-odor, no air pollution, no C02 gas and no harmful second-hand smoke
6. No need to completely withdraw from nicotine and there are many different flavors and products to fit your lifestyle

     The only drawback is that the battery is only good for about 2 hours used before it must be recharged and the vapor refill pack lasts about 200 puffs (about a pack of tobacco-cigarettes) then you need another.  Check out their website for full information.
