A Guide to Cannabis Holidays Beyond 420
By now, everyone’s heard of 4/20, but 4/20 is far from the only (or even biggest) cannabis holiday in the community. The cannabis community has built quite a calendar that traces back to the prohibition days. Some of these dates are rooted in genuine activism, others are built around a clever bit of numerology, and one has become the biggest single sales day of the year almost by accident.
4/20 (April 20): The Big One
4/20 traces back to five California students in 1971 who used "420" as private shorthand for their after-school search for an abandoned cannabis patch. Decades later, through a connection to the Grateful Dead's inner circle and a 1991 High Times article, it grew into the largest cannabis celebration in the world, with festivals, gatherings, and deep dispensary sales every April 20th.
7/10 (July 10): Dab Day / Oil and Concentrates Day
If 4/20 belongs to flower, 7/10 belongs to concentrates. The date works as a piece of wordplay. Flip "710" upside down, and it reads "OIL," a fitting nod to a day built around wax, shatter, live resin, rosin, and vape cartridges.
The term gained real traction after a 2013 LA Weekly article, and Denver hosted the first known formal 7/10 celebration that same year. It's widely considered cannabis's second- or third-biggest retail holiday, and dispensaries run concentrate-specific deals to honor it and to give extract enthusiasts a nudge to try new formats.
Green Wednesday: The Day the Sales Peak
Here's a genuine surprise for anyone assuming 4/20 dominates every metric. By pure sales volume, Green Wednesday, or the Wednesday before Thanksgiving, is the biggest cannabis shopping day of the year in most legal markets.
The logic is simple. People are stocking up before a long holiday weekend spent with family, often deliberately, which is why dispensaries lean into it with Black Friday-style discounts of their own. 4/20 still wins on cultural energy and turnout, festivals, gatherings, and public visibility, but Green Wednesday wins on the register.
Bob Marley Day (February 6)
Bob Marley Day is, as you can imagine, there to mark the birthday of reggae icon and outspoken cannabis advocate Bob Marley. This date has become an informal celebration of his music, his Rastafarian faith, and his decades-long association with cannabis culture.
Despite years of internet rumors, Marley's birthday and death (May 11, 1981) have no actual connection to 4/20's origin. That one’s brought on by the Waldos. Bob Marley and 4/20 ended up culturally linked through decades of shared iconography, not through any real historical overlap.
Hash Bash (First Saturday of April)
Hash Bash is less a vibe-based holiday and more a genuine piece of activist history. It started in Ann Arbor, Michigan, in 1972, growing out of local outrage over poet and activist John Sinclair's ten-year prison sentence for possessing two joints.
Held annually on the University of Michigan campus ever since, it's one of the longest-running cannabis-related gatherings in the country, combining speeches, live music, and open cannabis use in a public protest-meets-celebration format that's stayed consistent for over 50 years.
Victims of Prohibition Day (October 5)
October 5th is observed in parts of the legalization movement as a day to reckon with prohibition's ongoing human cost, specifically, the people still incarcerated for nonviolent cannabis offenses that are legal, or effectively decriminalized, in a growing number of states. Advocacy groups estimate the number of people still serving time on cannabis-related charges in the millions, even as legal markets generate billions in tax revenue around them.
It's a deliberate counterweight to the retail-driven, celebratory tone of dates like 4/20 and 7/10, and a reminder that legalization's benefits haven't reached everyone prohibition harmed, and that expungement, clemency, and record relief remain active, unfinished parts of the broader reform conversation.
Global Marijuana March / Cannabis Liberation Day
Global Marijuana March (known in New York as the Cannabis Parade & Rally, and in the Netherlands as Cannabis Liberation Day) is a coordinated day of advocacy-focused marches and rallies pushing for legalization and reform. It started in 1999, and it's one of the more overtly political dates on the cannabis calendar, with a lineage tracing back to early-1970s counterculture organizing.
Jack Herer Day (June 18)
Named for the cannabis activist and author of The Emperor Wears No Clothes (and, not coincidentally, for the strain named after him), this date honors Herer's decades of legalization advocacy.
Herer spent his career testifying, organizing, and pushing ballot initiatives forward well before public opinion had caught up to him, and he lived just long enough to see recreational cannabis pass in Washington State in 2012, days before his death.
June 18th marks his passing, and it's observed less as a party and more as a moment of tribute, and a day to recognize how much of today's legal cannabis landscape was built on groundwork laid by people who did the unglamorous, often thankless work decades before it paid off.
Why These Dates Matter
You’ll notice how cannabis holidays split fairly cleanly into two categories: activist history (Hash Bash, Victims of Prohibition Day, the Global Marijuana March, and Jack Herer Day) and culture-driven celebration or retail events (4/20, 7/10, and Green Wednesday). Both sides of the coin matter to how the culture built itself, even if only one half shows up prominently in a dispensary's sales calendar.
Celebrate Cannabis Holidays with Quality Roots
Cannabis's calendar is a mix of protest history, community celebration, and modern retail tradition that's evolved over more than 50 years. Whichever date you're marking, it's worth knowing the actual story behind it, not just the discount attached to it. But we know discounts matter, too, so we usually have good ones to honor the special days. So, stop by your nearest Quality Roots location to see what's on for the occasion.
