The International Day against Drug Abuse and Illicit Trafficking is a United Nations International Day against drug abuse and the illegal drug trade. It is observed annually on 26 June, since 1988, a date chosen to commemorate Lin Zexu's dismantling of the opium trade in Humen, Guangdong, just before the First Opium War in China. The observance was instituted by General Assembly Resolution 42/112 of 7 December 1987.
The UN's 2007 World Drug Report puts the value of the illegal drug trade at US$322 billion a year.
