[A metaphor of the nurse's work in addictology]. / La métaphore des ornières et le travail infirmier en addictologie.

The mechanism of addiction can be compared to a rut in a road, towards which patients are attracted and into which they inevitably fall. The role of the nurse in addictology is to lead the patient to consider other roads, to tread a new path taking them in a more positive direction. It is on this condition that programmes based on substitution can prove effective.
