Sometime in the 1990s, I smoked some pot. Unlike Bill Clinton, I inhaled. And I didn’t exhale until about 45 minutes ago. So I’m pro pot. And 4-20 was invented at my high school. But I must say, I find the current iteration of the holiday to be pretty ridiculous considering the ubiquity of the behavior it celebrates. Who knows, maybe I’m just burned out. “The prevailing explanation is that it started in the 1970s with a group of bell-bottomed buddies from San Rafael High School, in California’s Marin County 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 at nearby Point Reyes, so he drew a map and gave the teens permission to harvest the crop, the story goes.” 4-20 grew from humble roots to marijuana’s high holiday.
