What Is Hash Bash?

Taking place annually on the first Saturday of April high noon at the University of Michigan Diag, Hash Bash began as a protest to raise awareness for the unfair arrest and sentencing of John Sinclair. John was sentenced to 10 years of prison for two joints in 1969.

The news about John receiving such a harsh sentence for such a harmless crime quickly spread around the world. Many came together at the University Of Michigan to rally against the unreasonable laws and the event brought the likes of many musicians and activists including John Lennon who debuted his new song, "It Ain't Fair John Sinclair" during the event.

Through the efforts of Leni Sinclair and the rally at the U of M the State Supreme Court of Michigan took notice and decided to change the law that led to John's arrest allowing a small gap of time where cannabis was suddenly legal in Michigan. 

The first Hash Bash was held on April 1st 1972 at the U of M Diag as a reaction to that ruling of the Supreme Court. Since then the event has grown into infamy.

With thousands gathering to protest annually at Hash Bash the event helped legalize medical and recreational cannabis in Michigan and sparked a movement that is still growing around the world to this day.

With cannabis legalized in Michigan the focus has shifted to raising awareness for federal decriminalization, ending the war on drugs, legalizing entheogenic substances and standing in solidarity through Counter Culture to express our fundamental American rights of Life, Liberty and the Pursuit Of Happiness.

Partnering up with Great Lakes Expungement Network the Hash Bash Organization now helps raise funds to expunge the criminal records of those effected by the war on drugs. Great Lakes Expungement works tirelessly to expunge records for FREE to help people with former convictions get their lives back on track.
