A lot of people think that it is no problem to smoke a cigarette now and then; especially when together with friends or colleagues who smoke. Experience has shown that this will not work. The addiction will reappear gradually and often the person will return to smoking as much as they were before they quit. With the first cigarette the addiction will return, unnoticed at first. This may lead to symptoms of a withdrawal during the days after the smoked cigarettes. If such a person has stress in addition, he or she will not resist the urge to smoke.
