"420 celebrations" refer to events held on April 20th each year, where people gather to celebrate and advocate for the use of cannabis. The term "420" originated from a group of high school students in the 1970s who would meet at 4:20 PM to smoke marijuana. Over the years, this time has evolved into a cultural phenomenon, symbolizing the broader movement for marijuana legalization and cannabis rights. During these celebrations, participants often enjoy music, food, and various activities while sharing their love for cannabis. Many cities host large gatherings in parks or public spaces, where people come together to promote awareness about the benefits of cannabis and to advocate for its responsible use.
