Smoking represents a major public health problem because of its high morbidity and mortality rates. Nearly half of the deaths in the lower class are caused by smoking. The socially deprived are physically and psychologically vulnerable. The instability of their situation increases the difficulty to invest in smoking cessation and certain time orientations linked to this social deprivation represent negative factors in the prognosis. Socially deprived populations do not understand the consequences of smoking unless they are in denial of the risks. The motivation to stop is essentially financial. The perception of smoking cessation is taken as a deprivation of pleasure. Independently of the social deprivation factors, taking into account the time perspective conveys necessary information of appropriate care.
