When most people think of cannabis holidays, 4/20 is the first date that comes to mind. However, another celebration has steadily grown in popularity among cannabis enthusiasts over the past decade: 7/10, commonly known as “Oil Day.” Every year on July 10th, cannabis consumers and dispensaries celebrate concentrates, extracts, and the innovation that has transformed the modern cannabis industry. While it may not have the same mainstream recognition as 4/20, 7/10 has become an important day for those who appreciate products like live resin, rosin, wax, shatter, and vape cartridges.
The meaning behind 7/10 is surprisingly simple. When the numbers 710 are turned upside down, they resemble the word “OIL.” As cannabis concentrates became increasingly popular in the early 2010s, members of the cannabis community adopted “710” as a playful reference to hash oil and other cannabis extracts. Before long, July 10th became an unofficial holiday dedicated specifically to concentrate products, much like April 20th celebrates cannabis culture as a whole.
Although cannabis concentrates have existed for centuries in traditional forms like hashish, today’s concentrates are the result of significant advances in extraction technology. Modern techniques have made it possible to preserve cannabinoids and terpenes with remarkable precision, producing flavorful and potent products that appeal to a wide range of consumers. Solvent-based extracts such as live resin and shatter, along with solventless options like rosin, have become staples on dispensary shelves, giving consumers more choices than ever before.
Unlike 4/20, which has well-documented origins tracing back to a group of California high school students known as the Waldos in the early 1970s, 7/10 developed more organically within the cannabis concentrate community. Around 2011 and 2012, the term began appearing on cannabis forums, social media, and at industry events as concentrates experienced rapid growth in legal cannabis markets. The upside-down “OIL” connection resonated with consumers, and dispensaries soon began hosting promotions, product launches, and educational events centered around the holiday.
Today, 7/10 is celebrated by cannabis retailers across North America with discounts on concentrate products, vendor pop-ups, educational demonstrations, and opportunities for consumers to learn more about different extraction methods. Many people use the holiday to explore new products, compare solventless and solvent-based concentrates, or simply stock up during some of the year’s best concentrate sales.
As the cannabis industry continues to evolve, concentrates remain one of its fastest-growing product categories. Improvements in cultivation, extraction, and quality control continue to produce cleaner, more flavorful, and more consistent products than ever before. Whether someone prefers live resin for its rich terpene profile, rosin for its solventless purity, or distillate for its versatility, 7/10 has become a celebration of the craftsmanship and innovation behind modern cannabis concentrates.
Whether you’re an experienced concentrate enthusiast or simply curious about the growing world of cannabis extracts, July 10th serves as a reminder of how far the industry has come. The next time you see a dispensary advertising 7/10 Specials or Oil Day Deals, you’ll know the story behind the date—and why turning 710 upside down became one of cannabis culture’s most recognizable symbols.
