have you tried electronic cigarettes? There is a disposable electronic cigarette you can get the nicotine from but not the tar or other harmful additives that cause cancer or heart disease. They sell at some convenience stores in my area for around 7 US dollars and equal to around 2 packs of cigarettes. They don't make your breath, clothes, hair, car or house smell bad and it is like smoking a real cigarette. you just take a puff when you crave the nicotine and pretty soon you won't want a real cigarette, and thereafter you will be able to wean yourself off the nicotine too, (like the gum.) You don't have to worry about putting it out or burning anything because there is no fire or heat involved.Some people invest in those expensive electronic cigarettes but Square cigarettes do the same thing and they are disposable without the huge investment.
