A lot of people are not able to stop smoking. Some would like to but always end up finishing a stick. The problem is when they are starting to annoy those who are non-smokers. They might always need to talk and interact with people who do not smoke. An alternative is to use an electric cigarette. It also looks like a normal cigarette but without the burning or tobacco. It gives inhaled doses of nicotine that is vaporized. It is battery operated and produces only smoke vapor that is odorless and disappears in a few moments so others will not be so annoyed by it.
