Divided into 5 sections : the first explores the nature and scope of drug-related harm in workplaces. The second focuses on the legal and policy framework for responding to drug problems, the responsibilities and rights of employers and employees. The various interventions that can be implemented in the workplace are reviewed in the third section, with the costs and potential benefits of each outlined. In the fourth section, lessons from other domains - the results of research into how best to ensure and enhance health and safety in the workplace, and how to successfully implement organisational change - are reviewed. A final section draws together some practical implications of the work reviewed in the book, and case examples illustrate approaches adopted in a range of workplace settings.
