In this paper, we study the smoking behavior of students aged from 18 to 25 using four cross-section data sets collected in France from 1997 to 2006. We focus on the role played by student income and parental resources. We find that both the probability of smoking and the number of cigarettes smoked are positively correlated to family resources. Among students, only wages earned and transfers received from parents increase smoking participation. However, sensitivity to income remains weak since a rise of 1% in income of either the students or their parents leads to an increase in smoking prevalence of about 0.15-0.20%.
