If you’ve heard people counting down to April 20 and wondered what all the planning is about, you’re not alone. What is 4/20? In short, it’s the most widely recognized date on the cannabis calendar. A day that started as insider shorthand grew into something that now shapes retail calendars, community gatherings, and legal cannabis access across the country.

The Real Story Behind 4/20 History
The origin of 4/20 traces back to a group of five students at San Rafael High School in California who called themselves the “Waldos.” In the fall of 1971, they caught wind of an abandoned cannabis crop supposedly planted near Point Reyes. They agreed to meet at 4:20 PM after school by a statue of Louis Pasteur on campus to start their search. They never found the crop, but they kept using “4:20” as a code among themselves for cannabis.
The phrase spread quietly through Grateful Dead fan networks across the late 1970s and 1980s, eventually making it into broader cannabis culture. By the 1990s, 4/20 had become a symbol of cannabis activism and community, used by advocates pushing for legalization at a time when that outcome was far from guaranteed.
A few myths worth clearing up: 420 is not a police code for marijuana. It doesn’t refer to the number of chemical compounds in cannabis, either; cannabis contains over 400 known compounds, including cannabinoids and terpenes. And it has nothing to do with Bob Marley’s birthday, which was February 6, 1945.

Preparing for 4/20: A Practical Guide for Shoppers
4/20 is one of the busiest retail days of the year for cannabis dispensaries nationwide. Here are the right steps to take:
Check the menu early.

Plan for wait times.
Foot traffic on 4/20 runs higher than on a typical weekday. If you’re planning to stop in mid-afternoon, expect lines. Shopping in the morning or closer to opening is one way to move through faster.
Bring a valid ID.
Massachusetts law requires every customer to be 21 or older with a government-issued photo ID to enter a dispensary. There are no exceptions, and this applies to everyone.
