This third booklet of the World Drug Report 2022 has a dual focus: opioids and cannabis. The first chapter of the booklet provides an overview of opioids as a group of substances and their patterns of non-medical use at the global level. It also reviews the latest trends in the global supply of opiates and synthetic opioids and the availability of pharmaceutical opioids for medical consumption. Issues specific to regional patterns and trends in opioid markets are also analysed, including the opioid crisis in North America and in Africa and the Middle East. The chapter also includes a discussion of the potential impact, in the region and worldwide, of changes in opium poppy cultivation and opium production in Afghanistan. reireg
