This research focuses on the analysis of cannabis consumption amongst young people, explaining this phenomenon by way of analysing the differences between cannabis smokers and non-smokers in order to shed light on whether cannabis is linked to specific leisure activities, and, moreover, whether it is connected to the intensity and variety of particular "problematic" free-time activities, such as binge drinking. In addition, we show that cannabis use is not connected to any specific values but, rather, to a lack of certain values. Finally, there are certain practical implications that could improve social marketing campaigns which carry an antidrug message based on adopting a diversified set of values and target especially problematic free time activities. We also suggest future lines of research.
