Here are nine 4/20 events happening around Springfield next month

Wednesday marks one month until 4/20, or April 20, the unofficial holiday celebrated by marijuana consumers across the globe. Several Springfield businesses and organizations are honoring the day as the state surpasses its one-year anniversary of recreational marijuana legalization.

The story behind how 4/20 became the unofficial marijuana holiday is a matter of debate, but there are a few theories that remain popular.

Some believe it’s because 420 has, over the years, been used by police as the radio code for marijuana. Others tie 4/20 to Bob Dylan’s song “Rainy Day Women #12 & 35” with its refrain, “Everybody must get stoned” and that the product of 12 and 35 is 420, according to PBS. But perhaps the more likely story centers around a group of California high school friends in the 1970s.
