Every year on April 20, cannabis consumers across the country mark a holiday that has grown from an inside joke into one of the biggest shopping events in the legal cannabis calendar. If you’ve been asking “what is 4/20?” or searching for the 4/20 meaning behind all the buzz, we’ve got you covered. And if you’re in the Quad Cities looking for a place to celebrate, Terrace Cannabis in Moline and Milan is ready to make this one count.

The 4/20 History Behind the Holiday
The origin of 4/20 goes back to 1971 in San Rafael, California. A group of high school students who called themselves “The Waldos” would meet after school at 4:20 PM near a statue of Louis Pasteur on their campus. Their plan: to track down an allegedly abandoned cannabis crop near Point Reyes. They never found the crop, but the time “4:20” became their shorthand for cannabis.
The phrase spread quietly through Grateful Dead fan communities, known as Deadheads, who circulated the term at concerts throughout the 1970s and 1980s. By 1998, High Times magazine had published the Waldos’ story, and the term reached a national audience.
Over the following decades, 4/20 shifted from a time of day to a 4/20 cannabis holiday recognized around the world. Today, April 20 is associated with community gatherings, legalization advocacy, and some of the largest retail promotions the cannabis industry sees all year.
What 4/20 Looks Like in the Quad Cities
The Quad Cities metro spans both sides of the Illinois-Iowa border, with Moline, Rock Island, and East Moline on the Illinois side, and Davenport and Bettendorf across the river in Iowa. The region is home to roughly 380,000 residents and draws steady visitor traffic to destinations like the John Deere Pavilion in Moline, Vibrant Arena at The MARK, and the Ben Butterworth Parkway along the Mississippi riverfront.
We’re gearing up for an epic 4/20 celebration. Our full lineup of deals and specials will be announced soon.
