The best and most up to date book I have seen on quitting smoking recently is called "How to stop smoking, now and for ever, by Dr Harry Alder and Karl Morris. From How To Books isbn 978-1-84528-223-3.
It emphasises that smoking is a learned behaviour, we were not born to smoke, so like all habits they can be unlearned in about 7-14 days - if we are motivated to do so.
They also emphasis that the fear of stopping is a hurdle to be overcome. Also that although nicotine is highly addictive it only stays in our body for about 3-7 days so if we can get past that then we are well on our way to quitting.
Also that too many people have wrongly been convinced that smoking calms them down. But it cannot and does not, because this drug is a stimulant, not a relaxant.
Stimulants stress up our bodies, make our heart pump faster and make us anxious.
The confusion in smokers minds is this. When we need a fag, we take our tobacco hit, just like the heroin user does and the immediate relief that comes is relief from our craving (addiction) to the drug. When that craving is satisfied we feel "relaxed" until a few seconds later when our body is screaming out for more of our drug of choice - nicotine, kicks in again
Depriving our body of the nicotine for 3-7 days clears it out of our system, so there is no craving left. What is left is the social and mental habit we have created for ourselves, that requires the drug tobacco to get us by the day.
Fact; The most successful method that quitters from tobacco use , is just to decide to stop, and getting on with it. No patches, no classes, no acupuncture or any other aid is required. It is all about the power of the mind. Smokers have over a long time convinced themselves that they cannot quit, so they don't.
fact 2: there are around 4,000 different chemicals added to commercial cigarettes to try to hook different sorts of smoker in. We do not even know what some of these substances are. The new off the street so called cheap fags from China are known to be highly toxic with up to 30 times more dangerous chemicals like lead in them than the legal versions.
