Let me tell you how this works....... 

blu eCigs are very similar to the traditional cigarettes in that they look, feel and taste exactly the same. The big defference is that blu eCigs delivers all the pleasures of smoking without any of the tar and carcinogens that are considered a common mark for traditional cigarettes.

Here's a quick review of the technical side....

blu is brought about by the very latest in microelectronic technology in the form of a small rechargeable battery built into the cylinder while the replaceable cartridge contains water, propylene glycol, nicotine as well as several unique flavors exclusive to blu.

With blu, the act of inhaling (aka smoking) produces the satisfaction smokers desire and, for the sake of the traditional smokers, it also triggers a process that releases "smoke" which is actually a vapor that evaporates into the air within seconds

And that's not even the best part, The Blu E-cig is incredibly inexpensive, roughly $1.25 USD a pack, so you need not worry about the rising tobacco costs ever again. And wait a moment, it gets better. The E-cig is completely earth-friendly, in that it is made from recycled plastic and can itself be recycled. And since there is no actual tobacco and tar in the E-cig, it is not near as dangerous to the human body as the traditional cigarette. And in closing, I say "Smokers of the World, Light up! with the blue light and live long, happy lives."
