The day has become so inextricably linked with the herbal leaf that a Google search lists 420 as simply one of the date's holidays and observances (along with UN Chinese Language Day). But how exactly did the association between 420 and marijuana begin?
The story told on countless couches around the country is that "420" is police code for a marijuana arrest. But take a clear-eyed look at that explanation, and it goes up in smoke.
Arrest in progress
It turns out, the terminology that linked 4/20 with smoking pot took root in Northern California in the early 1970s, said Steve Bloom, the publisher of CelebStoner and the founder of Freedom Leaf magazine.
Bloom, however first came upon the connection when he was given a flier at a Grateful Dead concert at the Oakland-Alameda County Coliseum in 1990. The flier recounted the now-famous apocryphal tale that 420 was police code for a marijuana arrest in progress.
"The makers of the flier thought it was a good idea to turn that around and smoke on 4/20," Bloom told Live Science.
The flier urged its readers to celebrate 4/20 as "the grandmaster of all holidays," when they should meet up with friends to smoke pot together at 4:20 p.m. on 4/20, Bloom said. [5 Pot Facts for 4/20]
Bloom wrote about the flier in High Times magazine, and the idea soon took off, he said.
But the police-origin story was off the mark, as that is not the code used for a marijuana bust.
"A few years later a few other people got in touch with High Times claiming they were the rightful owners of 420," Bloom said.
It turned out that a group of men who called themselves the Waldos went to high school in San Rafael in California during the 1970s, when the Grateful Dead lived there and the hippie culture reigned supreme. One day they heard a story from a friend about a patch of weed being grown by a U.S. Coast Guard member near the coastal town of Point Reyes. The Coast Guard member was too scared to go harvest it, so the Waldos decided to go on a treasure hunt for the marijuana patch. They decided to meet at a Louis Pasteur statue near campus at 4:20 p.m. to accommodate their school schedules, before heading off in search of the green gold, according to 420Waldos.com, a website set up by the high-school group of friends.
The pot search routine went on for weeks and the group agreed to meet every day at "420 Louis" to continue the search. Though it wound up being a wild goose chase, it eventually gave rise to the shortened term "420" to denote smoking marijuana.
"We didn't know we were creating history at the time, it was just a private joke we were telling between ourselves," said Dave Reddix, one of the original waldos, who is now an independent filmmaker in San Francisco.
The Grateful Dead lived in San Rafael at the same time as the Waldos, and the group sometimes hung out in "deadhead" circles, even lingering backstage after shows. Gradually, their terminology spread through the Grateful Dead community into the wider stoner culture, Bloom said.
The Waldos not only spoke with an editor at High Times (not Bloom) and signed statements attesting the truth of their story, but they also provided documents, such as old letters referring to marijuana by its numerical nickname, old high-school newspapers using the term, and even a "420," batik-dyed marijuana flag, according to 420Waldos.com. Though they were initially anonymous, but in the late 1990s, a few of the original group have come forward with their real names. Recently, they even found the U.S. Coast Guard member, who is now homeless, and finally found the location of the original pot, Reddix said.
Wider cultural trend
But how exactly did the term make its way from a local term to a global holiday? The flier that Bloom and others received at the Oakland Grateful Dead concert may have been the catalyst that launched "420" from local Northern California underground slang to the central day for major marijuana celebrations and protests throughout the world. But the false association between police busts and 420 predates the Grateful Dead concert by at least 15 years, said Steve Capper, one of the Waldos, who is now in the financial services industry in San Francisco.
"The first time I heard it, I was going to school in Southern California," somewhere between 1974 to 1975, Capper told Live Science. "I'd fly back and would pass by a high-school kid hitchhiking."
After picking them up, he would ask them if they knew what 420 was.
"They'd say 'it's a police code for marijuana,'" Capper said.
The real turning point, however, was the Oakland concert, Bloom said.
"I was not the only person who got the flier, but was the one who was able to spread it out through the magazine," Bloom said. "Over the years, it just kind of picked up steam. That was really what started to build up the 4/20 phenomenon."
Exactly who created the flier, and launched 4/20 into a global day of celebration of all things cannabis, however, is still unknown.
"The mysterious deadheads behind the flier are the ones who created the holiday," Bloom aid. "It's become the stoner high holiday, and these guys are the people who created it."

It's time you learned how 4/20 became 'Weed Day'
There is something in the air today. Maybe you've noticed.
April 20, or 4/20, is known as "Weed Day" in some circles because the date corresponds with a numerical code for marijuana.
Yes, it seems arbitrary. So how did the number 420 come to represent smoking pot?
First, let's get the myths and rumors out of the way:
The legend of the California penal code
Some claim the number is drawn from the California criminal codes used to punish the use or distribution of marijuana. But the state's 420 code actually applies to obstructing entry on public land. So, not quite.
But the rumor sounds a lot like ...
The legend of the police radio code
Neither LAPD nor NYPD even have a code 420. San Francisco Police have one, but it's for a "juvenile disturbance."
So never mind that theory.
Then there's ...
The legend of the Dylan song
This one is a nod to Bob Dylan's song, "Rainy Day Women #12 & 35" and its lyric, "Everybody must get stoned."
Multiply 12 by 35 and you get 420.
Seems a bit of a stretch. And Dylan himself has never confirmed any link.
The story that appears to hold the most water is ...
The legend of the Waldos
According to Chris Conrad, curator of the Oaksterdam Cannabis Museum in Oakland, California, 420 started as a secret code among high schoolers in the early 1970s.
A group of friends at San Rafael High School in Marin County, California, who called themselves "the Waldos," would often meet at 4:20 p.m. to get high.
For them, it was an ideal time: They were out of school but their parents still weren't home, giving them a window of unsupervised freedom. They met at that time every day near a statue of Louis Pasteur, the scientist who pioneered pasteurization.

The 4:20 time became a code for them to use in front of their unsuspecting parents, and 420 gradually spread from there -- possibly via Grateful Dead followers -- across California and beyond. It's even the number of a California Senate bill that established the state's medial marijuana program.
What was shorthand for a group of friends can now be seen on T-shirts, in Tinder bios (420 friendly) and throughout pop culture.
And of course, on the calendar every April.
