I went to San Rafael High School, the campus widely credited with inventing 4-20. That gives my alma mater a decent place in marijuana history, but it’s nothing compared to Coronado High School in San Diego where some former classmates built one of the country’s biggest pot smuggling operations. “Before anyone had heard of the Mexican cartels and the Colombian kingpins, there was a group of Cali surfers, friends who discovered weed in the ’60s and — in a fit of stoner inspiration — figured out how to smuggle in the best, most potent stuff on earth. Over a decade, they built an empire that made hundreds of millions.” From GQ’s Joshua Bearman (of Argo fame): Coronado High.
