54th Annual Ann Arbor Hash Bash

Hash Bash Cup 2025 April 4-6, 2025.

For over 50 years, Hash Bash has become the event for cannabis advocates and allies. Many partake in ‘high noon’ at The Diag on U-M campus and gather to hear prominent cannabis advocates. Past speakers include Tommy Chong and John Sinclair, whose arrest sparked protests that evolved into the Hash Bash we know today.
