The seminar is based on Russell Turner’s doctoral dissertation, which was defended on 5 June 2020, studying the development of drug use, drunkenness, and criminal behaviour in early to mid-adolescence, to improve knowledge about how and why these three behaviours develop, and to contribute towards the development of theory that can have applications in prevention policy and practice.

Drawing on sociological, criminological and psychological theory, a new formulation of the differential development of these behaviours is outlined. The results and conclusions presented in the thesis have implications for the design of prevention policy and practice and for social work with young people.
