The electronic cigarette is presented as a healthier alternative to smoking that provides the action of smoking without tobacco or its carcinogens. It works by heating a nicotine solution into vapor that is inhaled. Tests on mice show no adverse effects, and users report improved lung capacity and feelings of well-being compared to smoking, though long-term human studies are still needed. While some may have propylene glycol allergies, it is present in many common products. The vapor released does not smell and dissipates quickly. Overall, the document argues that e-cigarettes are a safer replacement for smoking cigarettes.

1. The electronic cigarette is the worlds gift to smokers and non-smokers. Here is
what happens:
The battery is screwed into an atomizer which heats up and then vaporizes the
nicotine solution. When you pull on the e-cig, just as you would a real cig, the
solution is vaporized, you inhale it and then you blow it out. The action is
exactly like smoking a cigarette.
There is absolutely NO tobacco in this product. So what does that mean? There is
no second hand smoke. There are also no carcinogens. This product does not burn.
It heats up.
To answer your question on will it harm you: The jury is still out on this one.
Tests have been done on mice and they had absolutely no adverse effects
whatsoever. However, they have not been tested on humans. From my experience of
smoking and selling them, I have not had one complaint over almost two years of
anyone feeling bad. They have all said they see a massive change in their lung
capacity and general feeling as a whole. I can personally say that when I do
cheat and have real smokes, I feel it the next day. When I stick to my e-cig, I
feel much better.
As far as the Propylene glycol, this item makes up a good percentage of the
nicotine solution and it is found in everything from toothpaste to personal
lubricants to the makeup women apply to their faces. Some people have found that
they do have allergies to pg, but that allergy is often present way before using
the electronic cigarette.
Does it smell? Nope. It does not. The vapor that you release is water based so
it dissipates as soon as it leaves your body. No worries though if you blow
smoke rings... it is strong enough to make even the best smoke rings.
Is it better than a real cig? I think so. If you are interested in more

wikipedia entries to compare a tobacco cigarette to what is in an electronic
cigarette and a blog for further investigation.
