Why is 4/20 popular with weed fans?

420, 4:20 and 4/20 used to be an inside joke among people who enjoyed partaking in a puff of pot now and then. Now, the term is in the Oxford English Dictionary.

SEATTLE — Saturday, 4/20, marks the marijuana culture’s high holiday when college students -- and other weed fans -- light up at 4:20 to celebrate a decades-old tradition.

420, 4:20 and 4/20 used to be an inside joke among people who enjoyed partaking in a puff of pot now and then. Now, it's even in the Oxford English Dictionary.

With recreational pot now allowed in nearly half the states and the nation’s capital, and medical marijuana now legal in 38 states, those 4/20 celebrations are no longer secret. 

A lot of Americans say it's high time.

According to a Gallup poll last fall, 70% of adults support legalization, the highest level yet recorded by the polling firm and more than double the roughly 30% who backed it in 2000.

The history of 420

The origins of the date, and the term “420”, were long murky. Some claimed it referred to a police code for marijuana possession. Others said it's in reference to Bob Dylan’s “Rainy Day Women No. 12 & 35,” with its refrain of “Everybody must get stoned” — 420 being the product of 12 times 35.

But the prevailing explanation is that it started in the 1970s with a group of bell-bottomed buddies from San Rafael High School, north of San Francisco, who called themselves “the Waldos.” A friend’s brother was afraid of getting busted for a patch of cannabis he was growing in the woods, so he drew a map and gave the teens permission to harvest the crop, the story goes.

During fall 1971, at 4:20 p.m., just after classes and football practice, the group would meet up at the school’s statue of chemist Louis Pasteur, smoke a joint and head out to search for the weed patch. They never did find it, but their private lexicon — “420 Louie” and later just “420” — would take on a life of its own.

The Waldos saved postmarked letters and other artifacts from the 1970s referencing “420,” which they now keep in a bank vault, and when the Oxford English Dictionary added the term in 2017, it cited some of those documents as the earliest recorded uses.

How did 420 spread?

A brother of one of the Waldos was a close friend of Grateful Dead bassist Phil Lesh, as Lesh once confirmed in an interview with the Huffington Post, now HuffPost. The Waldos began hanging out in the band’s circle and the slang spread.

Fast-forward to the early 1990s: Steve Bloom, a reporter for the cannabis magazine High Times, was at a Dead show when he was handed a flyer urging people to “meet at 4:20 on 4/20 for 420-ing in Marin County at the Bolinas Ridge sunset spot on Mt. Tamalpais.” High Times published it.

“It’s a phenomenon,” one of the Waldos, Steve Capper, now 69, once told The Associated Press. “Most things die within a couple years, but this just goes on and on. It’s not like someday somebody’s going to say, ‘OK, Cannabis New Year’s is on June 23rd now.’”

For the Waldos, 4/20 signifies above all else a good time.

“We’re not political. We’re jokesters,” Capper has said. “But there was a time that we can’t forget, when it was secret, furtive. ... The energy of the time was more charged, more exciting in a certain way.

“I’m not saying that’s all good — it’s not good they were putting people in jail,” he continued. “You wouldn’t want to go back there.”

While the Waldos came up with the term, the people who made the flier distributed at the Dead show — and effectively turned 4/20 into a holiday — remain a mystery.
