How old is 420

Mark Waldo's father took care of real estate for the Dead. Patrick tells the Huffington Post that he smoked with Lesh on numerous occasions. He couldn't recall if he used the term around him, but guessed that he must have. So we used to go hang out and listen to them play music and get high while they're practicing for gigs.

But I think it's possible my brother Patrick might have spread it through Phil Lesh. And me, too, because I was hanging out with Lesh and his band [as a roadie] when they were doing a summer tour my brother was managing. The Waldos also had open access to Dead parties and rehearsals. When somebody passes a joint or something, 'Hey, Lesh, walking off the stage after a recent Dead concert, confirmed that Patrick is a friend and said he "wouldn't be surprised" if the Waldos had coined He wasn't sure, he said, when the first time he heard it was.

I'm very sorry. I wish I could help," he said. Wavy-Gravy is a hippie icon with his own ice cream flavor and has been hanging out with the Dead for decades. HuffPost spotted him outside the concert. Asked about the origin of , he suggested it began "somewhere in the foggy mists of time. What time is it now? I say to you: eternity now. As the Grateful Dead toured the globe through the '70s and '80s, playing hundreds of shows a year - the term spread though the Dead underground.

Once High Times got hip to it, the magazine helped take it global. The publicity that High Times gave it is what made it an international thing. Until then, it was relatively confined to the Grateful Dead subculture. But we blew it out into an international phenomenon. Sometime in the early '90s, High Times wisely purchased the web domain Bloom, the reporter who first stumbled on it, gives High Times less credit.

It wasn't really much of High Times doing," he says. The Waldos say that within a few years the term had spread throughout San Rafael and was cropping up elsewhere in the state. By the early '90s, it had penetrated deep enough that Dave and Steve started hearing people use it in unexpected places - Ohio, Florida, Canada - and spotted it painted on signs and etched into park benches. You guys ever look it up?

He had to admit that no, he had never looked it up. The term spread among the band's fans, known as Deadheads. Staff on the magazine, long the leading publication on marijuana, started using it.

They held ideas meetings at 4. Twenty years later another publication, Magazine, reported a claim by a rival group of San Rafael old boys that they had invented the term. He would know if I was saying, 'Hey, do you wanna go smoke some? Our parents didn't know what we were talking about," he added. The use of the term spread further thanks to the group's connection to The Grateful Dead.

The legendary rock band was based in the Marin County hills at the time, just blocks from the high school that the Waldos attended. The father of Mark Gravitch one of the Waldos managed real estate for the band, while the brother of Dave Reddix another Waldos member managed a Grateful Dead sideband. The brother was also good friends with Grateful Dead bassist Phil Lesh. The Grateful Dead practiced at a rehearsal hall in San Rafael, California: "So we used to go hang out and listen to them play music and get high while they're practicing for gigs," Reddix told the Huffington Post.

And the group—"they called themselves 'Waldos,' " Sloman says—started getting high with the Grateful Dead at their rehearsal studio in San Rafael. Around , High Times magazine senior editor Steve Bloom saw a flyer at a Dead concert that "told the story of , and that was news to me," he wrote in a copy of the magazine obtained by the Huffington Post. Bloom wrote that "" was originally California police code for smoking pot.

But it turns out the story on the flyer was horseshit. Bloom says "after about five years," the Waldos story emerged. Which is "about five years" if you're baked. So it checks out. This one's pretty simple. Oh how nice this would be, to trace the high holiday back to one of the best artists to listen to while engaging in the devil's lettuce. But alas, even though the song was recorded in , well before the Waldos did their thing, it's highly unlikely this is our one true source.

This one's a shut and closed case, too. Although it has been stated that there are "more than chemical compounds" in a cannabis plant, no one ever clearly stated that that number is
