The Fourth Canadian Edition of Drugs, Behaviour, and Society explores drugs and drug use from a variety of perspectives. This includes behavioural, pharmacological, historical, social, legal, and clinical contexts to help students connect the content to their own interests. The Fourth Canadian Edition explores recent trends, like the increased misuse of prescription opioid pain relievers, as well as drugs like alcohol and tobacco that continue to create serious health and social problems. Drugs, Behaviour, and Society features the latest information on drugs and their effects on Canadian society and behaviour. Every chapter has been updated with current research, enabling students to gain a deeper understanding of the individual problems and social conflicts that arise when others misuse and abuse psychoactive substances.
