In addressing drug and alcohol use in the workplace on an international level, it is necessary that employers, particularly those with multinational operations, take the context of each country in which they operate into account. The Institute for a Drug-Free Workplace identified 16 countries (France, Germany, Italy, the Netherlands, Norway, Spain, Sweden, the United Kingdom, Brazil, Canada, Mexico, Australia, Japan, Malaysia, Singapore, and Thailand) which are most likely to have operations and was most representative of a meaningful cross-section of workplaces around the world. Conducting a county-by-county analysis, this report's objectives are to provide insight into the extent and magnitude of drug and alcohol abuse in each country, to provide employers with an overview of the laws, regulations, and national attitudes that may impact their ability to successfully establish and maintain comprehensive substance-abuse prevention programs, and to facilitate the sharing of information and ideas by employers, drug-abuse professions, and policymakers whose common goals are to improve the health, safety, and working conditions of employees around the world.
