420: The Origin of a Magical Number
Cannabis has its own language and symbols—and none is more iconic than 420. But what lies behind those three digits? Why is April 20 (4/20) such a key date for cannabis culture? Here's a closer look at its roots, its evolution, and why it’s now celebrated worldwide as the ultimate cannabis day.
The most widely accepted theory places its origin in the 1970s in California. A group of students known as “The Waldos” used to meet at 4:20 p.m. to share a joint after school. “420” became their secret code—and through the music scene, especially thanks to their connection with the Grateful Dead, the term spread and eventually became part of the global cannabis vocabulary.
A Date and Time to Celebrate
Over time, April 20 became established as the international day to honor the plant and everything it represents: freedom, wellness, culture, and community. At exactly 4:20 p.m., millions of people around the world take a symbolic pause to light up, connect, or simply celebrate their bond with cannabis.
The Global Spread of 420
420 has become a global event—ranging from massive gatherings in cities like Amsterdam and Barcelona to intimate get-togethers in social clubs and private homes. It’s definitely a celebration, but it’s also a powerful tool for activism: a moment to demand rights, break down stigma, and push for fairer regulation.
In Spain, the date gains importance every year thanks to associations, collectives, and grow shops like Alchimia, which promote a responsible, informed, and accessible cannabis culture.
