Based on the results of research carried out in 2010-2011, the purpose of this article is to analyse awareness-raising training on “the dangers of drug use”, specifically focusing on the conditions of their implementation. Created as a result of the 2007 Acts, these training courses are a new penal response aimed at making users, especially non-dependents and socially accepted recreational cannabis users, aware of the social and health risks they are taking. The article describes the conditions and format of the training courses, which can vary depending on the type of structure that organises it (medico-social or socio-legal) and provides insight into the roles of the care professionals involved in this scheme. However, whatever the structure, a significant majority of the public believes that this kind of training will only have a limited impact on users’ habits. This finding raises questions as to how efficient this sanction is in terms of levering change. The awareness-raising training remains first and foremost a penal sanction. Aimed at people who already before the training course were not planning to change their cannabis use, this training is not personalised enough to trigger off the process of change.
