Hash Bash is an annual event held in Ann Arbor, Michigan on the first Saturday of April. The event is a collection of speeches, live music, street vending centered around the goal of reforming federal, state and local marijuana laws.
The first Hash Bash was held in 1971 Ann Arbor. The campus of the University of Michigan sits upon state property, and so anyone caught with marijuana on any campus location is subject to the more strict state marijuana laws.
