4/20 (Cannabis Culture Holiday) Date in the current year: April 20, 2024

There are different theories concerning the connection between the number 420 and cannabis subculture. The post popular theory says that the term 420 was first used by the Waldos, a group of teenagers from San Rafael, California. In 1971, they decided to search for an abandoned cannabis crop and agreed to meet near the Louis Pasteur statue at 4:20 p.m. They referred to their plan as “4:20 Louis”.

The phrase was eventually shortened to simply 420 and evolved into a code word used by teenagers to mean cannabis-smoking in general. Observances based on the number include the consumption of cannabis either at 4:20 p.m. on any given day or on April 20, as this date can be written 4/20.

On April 20, cannabis smokers celebrate and consume marijuana. Some people organize events in support of the legalization of cannabis.

If you intend to celebrate 4/20, keep in mind that possession of cannabis is illegal in most countries. As of 2023, countries that have legalized recreational use of cannabis are Canada, Georgia, Luxembourg, Malta, Mexico, South Africa, Thailand, Uruguay, plus the Australian Capital Territory in Australia and 23 states, 3 territories, and the District of Columbia in the US.
