What does 4/20 mean for marijuana users and why is it associated with weed?

You either look forward to it all year or roll your eyes every April: 4/20 is only a few days away.

If you’re celebrating in Florida, make sure your medical marijuana card is up-to-date, as smoking weed recreationally still isn’t legal in The Sunshine State.

If you don’t know what 4/20 is, here’s a guide to the cannabis-centric holiday, why weed smokers celebrate on April 20th and how you can celebrate in Florida.

What is 4/20?

If you smoke pot, you know that 4/20 is weed day – a day for a “puff, puff, pass” session (or many) with your pals – and you’ve probably already noticed it’s on a Saturday this year.

Here’s a not-so-fun fact: April 20th was also Adolf Hitler’s birthday. You may have heard a rumor in grade school that 4/20 is a holiday based around the late, great Bob Marley’s birthday, but that isn’t true. Bob Marley was born on February 6, 1945.

The true origin of why marijuana lovers spark up on 4/20 (or even associate the time 4:20 with smoking pot) isn’t clear, but there are a few rumored possibilities.

What is the origin of 420 for weed?

One of the most popular theories behind why April 20th became a day for getting high is a story of a group of high school students in the 1970s in California, who allegedly would meet to smoke pot every day at 4:20 p.m. But there’s little hard evidence to support this and it isn’t likely that a group of high school kids habitually smoking pot in the ‘70s could lead to “420” being a code for getting high across the globe.

Although a group of Californians published a slew of documents to prove this theory’s legitimacy, it’s hard to tell if it’s truly the origin of the holiday or using “420” as slang for smoking pot.

According to a Vox article on the origins of the holiday, “One common belief is that 420 was the California police or penal code for marijuana, but there’s no evidence to support those claims.”

So if it isn’t super-secret police-speak for illegal consumption of marijuana, it isn’t Bob Marley’s birthday and it wasn’t invented by a group of teenage stoners in the ‘70s, then what is it?

The answer isn't clear. No one really knows why or how, but April 20th is simply a day to smoke pot if you enjoy it, or advocate for its legalization if you’re a smoker who lives in a state where marijuana is only allowed with the possession of a medical marijuana card.
