A global collective catharsis, looking back at 100 years of negative history –since the 1925 Geneva Opium Convention first brought “Indian hemp” under international drug control. Meanwhile, cannabis also entered the International Pharmacopea in the same year.
Let’s re-examine this dual history in light of the millenia of positive interactions with Cannabis sativa L. by all human societies. During 99% of human history cannabis was neither prohibited nor problematic. We will do it again!

Una catarsis colectiva global, mirando hacia atrás a 100 años de historia negativa, desde que la Convención del Opio de Ginebra de 1925 incluyó por primera vez al “Cáñamo de Indias” en la fiscalización internacional de drogas. El mismo año, ¡el cannabis también ingresaba en la Farmacopea Internacional!
Reexaminemos esta historia dual a la luz de los milenios de interacciones positivas con Cannabis sativa L. por parte de todas las sociedades humanas. Durante el 99% de la historia de la humanidad, el cannabis no fue ni prohibido ni problemático. ¡Lo haremos de nuevo!

Une catharsis collective mondiale, revenant sur 100 ans d’histoire négative – depuis que la Convention de Genève sur l’Opium de 1925 a placé pour la première fois le “chanvre des indes” au sein du contrôle international des drogues. La même année, pourtant, le cannabis entrait également dans la Pharmacopée Internationale !
Réexaminons cette double histoire à la lumière des millénaires d’interactions positives avec le Cannabis sativa L. par toutes les sociétés humaines. Pendant 99 % de l’histoire humaine, le cannabis n’a été ni prohibé ni problématique. Nous le ferons à nouveau !

Celebrate the beauty of Cannabis cultures and resistance
Condemn the devastation of a 100 years of prohibition
If the history of Cannabis and humankind was a clock, prohibition would only be its last 2 minutes.
From time immemorial Cannabis has grown, been grown, and used for countless purposes. Worldwide, Cannabis provided clothing, food, feed and bedding for livestock, medicine, and a spiritual and social enhancer. But things changed brutally, only a hundred years ago.
The modern prohibition of Cannabis sativa L. plant (also known as hemp, marihuana, भांग, dagga, конопля, ganja, 麻, pot, ntsangu, haschisch, canapa, riamba, قنب, siddhi, kif, cáñamo, bangui, 大麻, chanvre, konopí…) originated before 1925 in Brazil, Egypt, and South Africa. The USA came much, much later.
But it was only in 1925 that Cannabis acquired a marked world character that continues to this day, as it entered international law for the first time.

1925 marks the birth of international treaty control over Cannabis/hemp
In 1925 (29 September), the Brussels Pharmacopoeia Treaty included for the first time Cannabis (herb, extract, tincture) in the International Pharmacopoeia, alongside other important medicines.
In 1925 also (19 February), the Geneva Opium Convention included “Indian hemp,” upon request from Egypt. For the first time, Cannabis had become an internationally-controlled drug. The conservative Brazilian, Egyptian, and South African governments had managed to extend to the entire planet their racist, colonially-biased, and intolerant views of an ancestral plant. The 1925 Opium Convention generated a descendance of treaties that continue to be in force worldwide today (like the Single Convention on Narcotic Drugs of 1961).
