420, also known as “Weed Day,” is a term and holiday that is celebrated by people who use cannabis. The origins of 420 are somewhat shrouded in mystery, but it is believed to have originated in the 1970s with a group of high school students in California who used the term as a code for smoking marijuana. Today, 420 is widely recognized as a day to celebrate and consume cannabis, and events and gatherings are held around the world on April 20th to mark the occasion. Despite its association with marijuana use, 420 has also become a symbol of the cannabis culture and the fight for legalization.
