The Evolution of 4/20: From Counterculture to Corporate Culture.

4/20, the unofficial holiday for marijuana enthusiasts, has its origins with a group of high school friends in California who called themselves "the Waldos." The term "420" spread through their association with the Grateful Dead and was later popularized by High Times magazine. Today, 4/20 is celebrated with music festivals, pot-shop discounts, and themed beers. While recreational marijuana is now legal in 21 states and the nation's capital, progress at the federal level has been slow. Activists are calling on President Biden to remove cannabis from the Controlled Substances Act and address the harm caused by the drug war.
