Cannabis in Afghanistan is illegal. It has been cultivated for centuries, and experienced relatively little interference until the 1970s, where after it became an issue both in international politics and in the finance of the series of wars which occurred in Afghanistan for forty years. In 2010, the United Nations reported that Afghanistan was the world's top cannabis producer.
While traditional cultivation and largely local consumption of cannabis was common in Afghanistan, the development of the Hippie Trail in the 1970s brought an influx of young tourists with an appetite for cannabis to Afghanistan. Hashish had been made nominally illegal in 1957, allegedly mostly as a concession to US pressure, but persisted as a common drug in the country. However, increased production and sale to Western tourists raised the issue to the level of a social problem for the Afghan government. In 1972 Afghan authorities confiscated large amounts of refined heroin and hashish intended for export, revealing the increasingly international scope of drug production in the country. US pressure on Kabul hashish syndicates in 1971 further increased the tension around the issue.
During this 1970s, several Afghan citizens were also linked to The Brotherhood of Eternal Love commune in the United States. Kabul merchant Hyatullah Tohki transported hashish with his brother Amanullah, who worked at the American embassy in Kabul.
In 1973, King Zahir Shah outlawed opium poppy and cannabis production, this time followed by genuine commitment to eradication, backed by $47 million in funding from the United States government. That summer Afghan troops aggressively tackled production, destroying farms and arresting or killing cannabis farmers. Zahir Shah was deposed by his cousin Mohammed Daoud Khan that fall, who ended the monarchy and established himself as President, but the momentum of the hashish trade had been interrupted, and Western smugglers re-routed to Pakistani sources, so the 1973 harvest was minimal, as were harvests for several years following.
