April 20th, commonly known as 4/20, is an informal holiday celebrated by cannabis enthusiasts around the world. The date is often associated with the consumption of cannabis, and many people gather to partake in smoking or sharing marijuana. The origins of the term "4/20" are believed to stem from a group of high school students in California in the 1970s who would meet at 4:20 PM to smoke together. In recent years, 4/20 has grown into a larger cultural event, with festivals, concerts, and educational activities promoting cannabis awareness and legalization. Many states in the U.S. have legalized cannabis for medical or recreational use, leading to increased public interest and participation in 4/20 celebrations.
