What Is Hash Bash?
Hash Bash started in 1972 as a protest following the arrest of poet and activist John Sinclair for cannabis possession. Over the decades, it has grown into a major annual event that blends protest, celebration, and education about cannabis culture and reform. While Michigan has since legalized recreational cannabis, Hash Bash continues as a space to advocate for ongoing legislative change and celebrate progress.
The heart of the event is always at The Diag, a central green space on the University of Michigan campus where crowds gather for speeches, smoke sessions, and community.
Schedule of Events
The main event kicks off at 12:00 PM on April 5. Expect a mix of advocacy speeches, live music, and crowd interaction. Prominent figures in cannabis activism, politics, and culture typically take the stage.
Running alongside Hash Bash is the Monroe Street Fair, which starts a little earlier at 11:00 AM and continues until 6:00 PM. This fair adds a more festival-like atmosphere with live music, vendor booths, and food trucks.

Getting There and Where to Stay
Ann Arbor is located near major highways and is accessible via Detroit Metropolitan Airport for out-of-town visitors. Parking can be challenging on Hash Bash weekend, so using rideshare or public transportation is strongly recommended.
Hotels and Airbnbs often book up quickly, especially those near campus. Plan ahead if you want to stay within walking distance of the action.
Know the Rules of Hash Bash
Recreational cannabis is legal in Michigan, but public consumption laws still apply. Technically, smoking in public spaces like parks or sidewalks is not allowed under state law—even at a cannabis-themed event. This event has always walked the line between protest and celebration, but attendees should use discretion and be aware of local regulations.
