What is an e-cigarette?

An electronic cigarette, also called e-cigarette, is a battery powered electrical device used to simulate tobacco smoke. It can provide nicotine, when using it, but not other harmful substances from tobacco, such as tar. E-cigarette produces vapor that can be inhaled. It looks like, feels like and tastes much like tobacco smoke, and has options for different levels of nicotine. Usage of e-cigarettes could, in principle, replace smoking tobacco and thereby avoid well known dangers that smoking brings. This is the main purpose of e-cigarettes.

Electronic cigarettes in today's form were originally patented in China in 2003 by Hon Lik, launched there in 2004 and exported abroad from 2006 under the brand "Ruyan". The idea goes back to a patent by Herbert A. Gilbert from the United States in 1963. However, at that time smoking was not considered risky and it remained only the idea. The language used about e-cigarettes is new, but it seems that using an e-cigarette increasingly is called "vaping" in contrast to "smoking".
