International Opium Convention Was Signed on January 23, 1912
January 23, 1912 is the day the International Opium Convention was signed in The Hague, the Netherlands.
This treaty, also known as the Hague Opium Convention, is the world’s first treaty about drug restriction.
The use of drugs such as opium, morphine and cocaine are regulated.
With the dismantling of the League of Nations in 1946 after World War II, the “Protocol to Amend Drug Agreements, Treaties and Protocols” took over the content of this treaty.
Furthermore, in 1961, the “Single Convention on Narcotic Drugs” took over.
