When it comes to smoking, apprentices are considered a 'vulnerable' population. They have been the subject of targeted approaches based on the assumption of common characteristics. In contrast to most public health studies, that assume homogeneity of vulnerable groups, this article, based on Lahire's 'theory of the plural individual', aims to examine inter- and intra-individual variability in relation to tobacco exposure. It is based on a secondary analysis of 30 interviews with apprentices in France on the stigma attached to their use in their different living environments. Our study confirms that the family and the Centre de Formation des Apprentis, as a whole, encourage smoking. It also provides a better understanding of the mechanisms by which inequalities are perpetuated (permissive rules, loans and gifts of cigarettes, spillover effects, lack of incentives to quit). Nevertheless, it allows us to observe that, in some families and in some companies, smoking is denormalised, even stigmatised. Several apprentice profiles emerge: those who are protected from tobacco and seem to be able to quit easily; those who are permanently confronted with it and for whom it is difficult to consider quitting or reducing; and those who are confronted with a plurality of norms, who seem ambivalent and whose consumption varies significantly. These results will allow us to adapt the interventions according to the profile of the apprentices and by including their entourage. In particular, it will be necessary to propose a 'go-to' approach that goes beyond the school setting and involves the family and the workplace.
