The International Day Against Drug Abuse (June 26) is observed annually on June 26 to draw global attention to the problems caused by drug use and trafficking. This day was added to the international calendar in 1988 following a decision by the United Nations General Assembly in 1987, which responded to growing concerns over increasing drug consumption and the expansion of trafficking networks during the 1980s. The purpose of designating this day was to encourage greater coordination among countries in addressing this global issue. Since 1988, the day has been officially marked in various countries. The aim is to raise public awareness about the dangers of drug abuse and to promote international cooperation to reduce both supply and demand. On this day, educational programs, awareness campaigns, and expert meetings are held worldwide. Governments, non-governmental organizations, and international bodies organize events to highlight the negative consequences of drug use and to promote prevention and treatment strategies. The day serves as an opportunity to review policies and actions taken and to consider ongoing challenges in the fight against drug abuse.
