As a smoker I can tell you that, for me and every one I have asked about this question/statement, is that niccing out (common phrase for the cravings outlined) is only secondary to the main problem in quiting, the actual act of smoking is the main addiction in alot of smokers as it is for me I have been 5 days without a smoke no headaches no normal syptoms of craving, I dont need a smoke I just like to smoke most people wont admit that, that they like the action of smoking.
that is why nicotine gums and patches and tablets will never ever work, and chances are or most of there friends also smoke to so if they pull out one of those nicotine inhalers when they start smoking there will be a big social stigma present adn that person will not feel accepted in any group, meaning the smokers will make fun of him, and the non-smokers will abuse him for smoking and no trying to quit smoking. The main thing to target and market is a way to get that nicotine craving because that is the secondary addiction into the body well making a inhaler that is disposible that comes in a package of ciggirettes of 20 and is accessable to the public. That on small doses cuts down nicotine and burns faster then the last pack, packs are on a teir style system i.e. step 1,step 2, etc, etc. until the last step becomes a placebo for nicotine and the action of smoking the ciggirettes becomes so short that once it is lit it will burn out in about 30 seconds that the person smoking it loses all the enjoyment they have felt in the past
