While not exactly the same as smoking a real cigarette, an electronic cigarette offers a plausible alternative. As many smokers may tell you, its often a matter of adapting to change. It's much the same as adapting to a different strength cigarette or a different brand. For example it would take smokers a while to get used to changing from regular cigarettes to menthol or vice versa.
Once you have adapted to the taste of an e cigarette vapor, you should notice that all other aspects are much the same as smoking tobacco. The taste is good, the smoke or vapor is realistic and the action of smoking is very similar. Many people who have tried to quit smoking will tell you that it is the action of smoking that is often as addictive as the nicotine or other products.
