Every year, 20 April is mentioned in numerous items of content devoted to hemp, cannabis and their cultural history.

Featured in many products and brands

The number 420 frequently appears in the names of products, companies, events, specialist media outlets or accessory collections. It has become an element of language widely integrated into the visual and cultural identity of the sector.

Its popularity now extends far beyond the circle of consumers and is one of the best-known references associated with cannabis.
