The history of cannabis and international control

How cannabis was included in the UN drug control system and the defections that have brought the international treaties to breaking point

This timeline draws on The Rise and Decline of Cannabis Prohibition, a report that described the history of international control, how cannabis was included in the current UN drug control system and the subsequent defections by countries and states that have brought the international treaties to breaking point.
