There's an intense ongoing debate regarding the existence of a Cannabis Culture. Its influence on art is strong. Since Hashish club of Paris in XIX century seems to have influenced Romanticism, Surrealism and Dadaism.
Cannabis is the only plant to have given birth to a music gender, Reggae. And since the first half of the XX century it's been tightly linked with art; From Frida Kahlo and Diego Rivera to Jazz composers such as Louis Armstrong.
It´s influence on current music and literature are pretty obvious. In what measure artistic movements were born directly from cannabis is a debate that requires getting in deep into it.
