The term originates from San Rafael High School in California (1971) among a group of cannabis-smoking teenagers called the 'Waldos,' who would meet at the campus statue of Louis Pasteur at 4:20 p.m.



Just like 420, 710 is a term used to celebrate dabs and cannabis concentrates on July 10th (7/10 in the U.S. form).
