Do you find yourself around the cannabis culture? Then you’ve likely seen the number 420 somewhere. On shirts, social media posts, calendars, and even products that are named after this number especially on April 20th (4/20). So what does 420 really represent and how did the whole thing get started? Here is some information on the truth about 420 and the myths surrounding it.

What does 420 Represent?

In general terms within the cannabis culture, 420 is commonly referred to as:
  • A way of saying “cannabis”
  • A time when you’re smoking or eating pot
  • A shared experience and community that understands each other
It is usually used as an example in everyday conversation such as:
  • “It is 4:20”
  • “420 friendly”
  • “Happy 420”
Regardless of all the rumors circulating, 420 is NOT a police code, NOT a scientific reference, and NOT a law.

How Did 420 Originate?

There are several stories being told about how the number 420 originated. The most documented and accepted explanation comes from the early 1970s in California. The true story is as follows:
  • A group of teenagers in California, known as the Waldos
  • Met after school at 4:20 PM
  • Their meeting time eventually became a shortcut for referring to smoking cannabis
  • The term was passed along through word of mouth
 Eventually, 420 became something more than a private joke to the rest of the world. Interestingly enough, the reason why the number remained, wasn’t due to the fact that it was a secret — but instead because it was so easy to remember and say.

Why April 20th (4/20)?

Once the number had gained popularity, April 20 (4/20) would naturally become an unofficial cannabis holiday. Here are some examples of what happens during 4/20:
  • Events and gatherings that celebrate cannabis
  • Promotions and special releases (depending on state laws)
  • Celebrations on social media
  • Acknowledging cannabis culture and its growth
Many people view 4/20 as less about getting high and more about recognizing cannabis culture and the movement.

Myths About 420 That Are Not True

There are many misconceptions surrounding the origins of 420. ❌ Some of the most common and false interpretations include:
  • A police radio code for marijuana
  • There are 420 chemical compounds in cannabis
  • A reference to a legal statue
  • Bob Marley’s Birthday (that is not his birthday)
  • None of these reasons have been proven to be factual.

What Does 420 Represent Today?

Today, 420 represents more than just a time or a number. Many times it represents:
  • Normalization of cannabis
  • Community and shared identity
  • Relaxation and enjoyment
  • Historical culture
With changing laws regarding cannabis and people’s views of cannabis, 420 has developed into a symbol and no longer a secret.

420 In Modern Cannabis Culture

You will see 420 referenced in:
  • Product Names

420 is now a universal symbol — and is understood by both those who do and those who do not consume cannabis — making it one of the most iconic cultural numbers of the past 50 years.
