The aim of the project was to characterise patterns and consequences of cannabis use specifically in relation to work activities, academic performance, driving habits and sexual behaviour - situations in which the cannabis user may be at risk of indirect harm from their drug use. More broadly, the project also aimed to evaluate the impacts of cannabis use (positive or negative) on quality of life, and to examine whether developments in detection/law enforcement (e.g. workplace drug testing) would influence patterns of use.
