For centuries, cannabis has played a crucial role in human survival as a source of energy, food, and clothing, as well as a therapeutic and euphoric medium. But for the past sixty years, it has been persecuted as a threat to its existence.

Until 1937, humanity used cannabis to meet many of its daily needs. After 1937, self-proclaimed "protectors" of society from drugs turned it into the "ultimate evil" and imposed a ban on its cultivation and the persecution of its users.

How did a plant that until the mid-19th century was considered one of the largest agricultural crops on the planet and an important raw material for the global production of many daily necessities transform from a blessing to a curse in just a few years? This critical question requires an answer, which cannot be indefinitely hindered by the combined political and economic interests behind the prohibition of cannabis and the persecution of its users.
