420

420 (pronounced "four-twenty") is probably the most well-known number in cannabis culture. It stands for consumption, for 4:20 PM, and – as a date – for April 20th, the scene's unofficial holiday.

Where does 420 come from?

The most common explanation leads to California in the 1970s: A group of students allegedly met daily at 4:20 PM to smoke together – "420" became their code word. The term spread through bands and scene media and became a worldwide abbreviation. Many other origin stories (police code, number of active ingredients) are considered myths.

What does 420 mean today?

• Time – 4:20 PM as "time to smoke."
• Date – April 20th (4/20) as a cultural holiday.
• Code word – general identifier of the scene.

April 20th as a holiday

Around April 20th, gatherings, events, and activities take place worldwide. For many, it's less about smoking than about community, culture, and – increasingly – about legalization debates. 420 has thus evolved from a code word into a symbol.
