This is the central idea behind Allen Carr's philosophy on quitting smoking. I found and copied this off Wikipedia. To this day I cannot believe how much easier quitting could have been had I been armed with this information and wisdom.
Carr teaches that, contrary to their perception, smokers do not receive a boost from smoking a cigarette: smoking only relieves the withdrawal symptoms from the previous cigarette, which in turn creates more withdrawal symptoms once it is finished. In this way the drug addiction perpetuates itself. He asserted that the "relief" smokers feel on lighting a cigarette, the feeling of being "back to normal", is the feeling experienced by non-smokers all the time. So that smokers, when they light a cigarette are really trying to achieve a state that non-smokers enjoy their whole lives. He further asserted that withdrawal symptoms are actually created by doubt and fear in the mind of the ex-smoker, and therefore that stopping smoking is not as traumatic as is commonly assumed, if that doubt and fear can be removed.
