e-cigarette - Interesting..

I recently read about this device called an e-cigarette. It claims that it is completely harmless to the individual smoking it or the persons around him/her. No second-hand smoke. Some of the benefits over traditional cigarettes claimed by this e-cigarette:

• No tar and other carcinogenic substance or harmful ingredients to human body .
• No ignition required , without the danger hence will not lead to the of over 4000 chemical substance produced by the ordinary cigarettes .
• It is harmless to other people and the environment , without the danger of second - hand smoking .
• No possibility to cause fire . It can be used safely in most NO-smoking places .
  

Cigarettes are such a bane and the worst part is, its addictive part - Nicotine isn't really the killer. Its the carcinogenic substances present in traditional tobacco cigarettes which causes health issues like cancer and respiratory issues. Nicotine is about as addictive as caffeine is. It is however absorbed much much faster by the body than caffeine, causing almost instant increase in blood pressure. Nicotine also has the effect of increasing alertness and enhancing mental performance. In the cardiovascular system, nicotine increases heart rate and blood pressure and restricts blood flow to the heart muscle. The drug stimulates the release of the hormone epinephrine, which further stimulates the nervous system and is responsible for part of the "kick" from nicotine. It also promotes the release of the hormone beta-endorphin, which inhibits pain.

Quite a few quit-smoking aids are available these days - nicotine patches, pills etc. This e-cigarette is a newer smoking-replacement aid. See this video for more information: http://www.youtube.com/watch?v=U81x8t2iMhw

I wonder how effective this is going to be. FDA still hasn't approved it by any way. http://www.cnn.com/2009/HEALTH/03/13/ecigarettes.smoking/index.html
