Abstract

Aim/Background

The general population is nowadays well aware that tobacco dramatically increases the risk of developing LC in the future. We hypothesized that personal smoking history, and the level of nicotine dependence in current smokers (CS), may affect the perception of this risk among healthy individuals.

Methods

The fourth French nationwide observational survey, EDIFICE 4, was conducted from June 12 to July 10, 2014 among a representative sample of 1602 individuals aged between 40 and 75 years, using the quota method. Individuals were questioned by phone about their smoking habits. Nicotine dependence was assessed in CS using the Fagerström Test (no dependence [group A]; low [group B]; moderate [group C] and high dependence [group D]). Risk perception was self-assessed: individually compared with the average-risk population, according to the effect of tobacco consumption, and to the effect of quitting.

Results

Among the 1463 subjects with no history of cancer, 481 (33%) were former smokers (FS) and 330 (24%) were CS, with a mean daily consumption of 14.2 cigarettes. According to the Fagerström Test, 52% of CS belonged to group A, 21% to group B, 18% to group C and 9% to group D. Only half the CS considered themselves at higher risk of LC than the average-risk population, while 4% of never smokers (NS) and 14% of FS had the same perception (P < 0.05). Among CS, the majority of those with a dependence on nicotine (B, C, D groups) considered themselves to be at higher risk of LC, while only 37% of non-dependent subjects (A group) had the same perception (P < 0.05). Surprisingly, 34% of FS considered themselves to be at lower risk of LC, versus 7% among CS (P < 0.05). Of the whole sample population, 34% considered that a daily consumption of up to 10 cigarettes was not associated with any risk of LC. The daily number of cigarettes considered “non-dangerous” was 1.8 in FS and 2 in NS, versus 3.4 in CS (P < 0.05). Less than 40% of individuals questioned were aware that the risk of LC never disappears after smoking cessation, but neither the smoking status nor the level of nicotine dependence significantly influenced this perception.

Conclusions

The considerable number of individuals who consider low cigarette-consumption to be safe demonstrates the urgency of initiating campaigns to address this question.
