Hash Bash returns to Ann Arbor without the Monroe Street Fair

Michigan’s biggest annual weed protest is taking over the University of Michigan Diag on April 4. But the longtime street fair spinoff event is taking a break for 2026.

MICHIGAN—Hash Bash is returning to the University of Michigan Diag at noon on Saturday, April 4, 2026, marking its 55th year as one of the country’s most visible pro-cannabis protests.

But the vendor-packed Monroe Street Fair that traditionally follows the event will not take place this year—leaving the Diag itself as the main attraction, featuring a few speeches, a big cloud of smoke at high noon, and thousands of people lighting up in broad daylight on a college campus.

What is Hash Bash?

Hash Bash started in 1972 at the University of Michigan as a smoke-in protest after the Michigan Supreme Court effectively voided the state’s marijuana law in a case tied to local activist John Sinclair, who had been sentenced to prison for possessing two joints.

What started as an act of defiance against the War on Drugs has since grown into one of the country’s longest-running cannabis demonstrations—a yearly reminder that while Michigan has legalized marijuana, federal prohibition and cannabis incarceration haven’t disappeared.

What happens at high noon?

This is the part that makes university administrators uncomfortable. The U-M Diag is proudly billed as the “heart” of campus. And it’s usually pretty crowded with stoners by 11 a.m.

Activists will be speaking from a microphone. Some of them will be passing out flyers. Expect folks to be there collecting signatures for local and statewide petition drives. People will definitely be smoking weed. And then, just before noon, a countdown will begin.

And when the clock strikes noon, everyone will be lighting up at the exact same time.

For decades, that collective cloud of smoke has been the defining image of Hash Bash with thousands of people openly lighting up in the middle of a public university campus in a massive act of civil disobedience. It’s part ritual, part reunion, and part reminder of how this all started.

Because while weed is now legal in Michigan, public consumption is still illegal. And smoking on campus is also prohibited—which is precisely why this moment still qualifies as protest.

Won’t I get in trouble for smoking weed in public?

Maybe. Probably not. Who knows? That’s the whole point.

Lighting up in public is illegal in Michigan. And the University of Michigan, like most federally funded institutions, maintains strict policies that prohibit the use of cannabis on campus.

But Ann Arbor has long been known for its relatively lenient enforcement when it comes to marijuana possession, with local ordinances treating it as a civil infraction rather than a criminal offense. And Hash Bash itself has rarely resulted in large-scale enforcement in recent years.

Does that mean there’s zero risk? No.

Just don’t be reckless. And if you choose to participate, understand what you’re doing and why the whole event exists in the first place. Hash Bash is real protest energy; not spring break.

What’s the deal with the Monroe Street Fair?

The Monroe Street Fair—held just off campus—is usually an extension of the day with glass vendors, live music, advocacy booths, and a distinctly more festival-like atmosphere.

That won’t be happening in 2026.

In a statement posted on Facebook, organizers said the fair could not be produced “logistically or responsibly” this year and confirmed that no vendor applications were accepted. They also described conversations about future events as “exploratory only” and urged people not to assume timelines or formats going forward, so it’s unclear if vendors will ever return. 

Why are people still showing up?

In a statement posted to Facebook, the organizing committee behind this year’s Hash Bash event described the annual protest as “sacred ground” and “a living act of resistance.”

And that hasn’t changed just because Michigan now has more than 800 dispensaries. 

Because at the end of the day, federal cannabis prohibition is still a thing. Tens of thousands of people nationwide are still incarcerated on cannabis charges. And the racial disparities that helped define the War on Drugs didn’t vanish when the industry went mainstream.

Hash Bash, at its core, is a reminder of that contradiction. The protest is showing up informed, intentional, and respectful of the history that brought legalization to Michigan in the first place.
