The biggest celebration day in cannabis culture is April 20. The April 20 (4/20) celebration originally started in the mid-1970s as the time of day after school, 4:20 p.m., for high school students in San Rafael, California to meet and smoke pot. The phrase "I'll see at you at 4:20" became code for, "I'll be there to smoke a joint with you after classes are over". Its origins in Canada happened in 1995 when two of my HEMP BC employees came to me at my desk and asked, "Marc, we'd like to have a 'Four-Twenty' celebration on April 20. We'd like your permission and approval to put on a Four-Twenty concert and rally and fun time in Victory Square next door." I responded, "No, we can't do that."
