Marijuana came to the western hemisphere with the help of the Spaniards in the middle of the sixteenth century. The Spaniards actively cultivated this crop, named “hempe” locally, in Chile. As cannabis spread throughout the continent, Virginia passed a law requiring all marijuana growers to grow only English and Indian cannabis.
Cannabis bans began to spread in the early 20th century. In the United States, restrictions were first introduced in 1906 in the District of Columbia.
In 1937, the Marijuana Tax Act was passed, which extended to cannabis. However, the United States soon had to abandon such a law since hemp helped the Americans a lot during the Second World War.
In the 1960s, cannabis became all too common, especially among youth and college students, with the result that cannabis became part of the cultural mainstream of the middle class. After that, the United States began an active fight against this drug. However, the experience of the latest years shows that the issue of cannabis is gaining more attention: many countries and states have already legalized the use of the drug.
