I just finished reading another thread about quitting smoking and someone asked about the e-cigarette. I took Chantix and quit smoking 2 months after smoking, well forever. Die hard to the core!!! The one difference this time is I now use the e cigarette for that manual habit we smokers get. This device is a battery operated tool that emits an odorless vapor. Can be used anywhere, even in an office. Plugs into a computer or wall socket to charge. The filter end od the cig unscrews and can be changed. Each filter is equal to a pack of cigs. they come in packs of 5 filters for $14. They have nicotine flavor, vanilla,mocha and menthol oh and chocolate. I started with the full flavor and worked my way down to the vanilla or mocha with no nicotine in them. medical professionals say the amount of carcinogens is in the E compared to a real cig is 1 to 100. Far less than real tobacco. It is in liquid form with an atomizer in the filter. The hardest thing to get accustomed to is the weight of the battery. I only use the flavored ones with no nicotine. No odors, no coughing every time I laugh and my teeth are whiter. Yes there is still a cost, but much less than regular cigarettes. Eventually I will pass mine on to someone else, but for now I'm happy I have progressed this far. I am nicotine free. For advice on which brand to look into pm me.
