420

420 是國際大麻文化的代號，可指 4 月 20 日（大麻節）、4:20pm（吸食時間）或暗指大麻本身。1971 年起源於加州 San Rafael 高中學生 The Waldos 的暗號，經《High Times》推廣後成為全球符號。與嘻哈文化密不可分。

420 is the international code for cannabis culture — referring to April 20 (cannabis holiday), 4:20 pm (smoking time), or marijuana itself. Originated in 1971 from the Waldos, a group of San Rafael High School students, and popularized by High Times magazine into a global symbol. Deeply intertwined with hip-hop culture.
