Hash Bash is an annual event held in Ann Arbor, Michigan, originally held every April 1st, but now on the first Saturday of April at noon on the University of Michigan Diag. A collection of speeches, live music, street vending and occasional civil disobedience are centered on the goal of reforming federal, state, and local marijuana laws. The first Hash Bash was held on Saturday, April 1, 1972 in response to the March 9th 1972 decision by Michigan Supreme Court declaring unconstitutional the law used to convict cultural activist John Sinclair for possession of two marijuana joints. This action left the State of Michigan without a law prohibiting the use of marijuana until after the weekend of April 1, 1972.[2] Chef Ra was a fixture of the Hash Bash for 19 consecutive years before his death in late 2006.[3]

The penalty for cannabis law violations in the City of Ann Arbor is a $30 fine and $25 court costs for a total of $55, and is a civil infraction ticket[4] (see Cannabis laws in Ann Arbor, Michigan). The campus falls under state, not city jurisdiction but "for decades, police have exercised discretion and a general tolerance for public marijuana use at the annual Hash Bash. Marijuana is openly consumed annually on the campus and few, if any, arrests occur. There is a general understanding that during this time, peaceful protesters can engage in the civil disobedience of cannabis consumption and police generally will not enforce state law."[5] There is a separate but heavily related event following Hash Bash just off campus known as the Monroe Street Fair, where there is usually a live show accompanying the many street vendors selling smoking accessories and Hash Bash graphic apparel, along with a Michigan NORML booth.


The second annual Hash Bash, in 1973, attracted approximately 3,000 participants. That year, state representative Perry Bullard, a proponent of marijuana legalization, attended and smoked marijuana,[6] an act which later earned him criticism from political opponents.[7]

Hash Bash participants did not encounter significant police interference until the seventh annual event, in 1978, when local police booked, cited, photographed, and released those participants alleged to be using illegal substances.[8] By 1985 the Hash Bash had a 0 attendance rate but quickly arose to become a major festival in Ann Arbor.[9]

The 2009 Hash Bash on April 4 celebrated 'medical' marijuana's victory in Michigan and was the largest gathering that the event has seen in years, with an estimated 1600 participants – an increased turnout which the Michigan Daily attributed to the "wider acceptance of recreational drug use both on campus and across the country."[10]

The 2010 Hash Bash on April 3 had an estimated 5000 attendees.[11]

The 2015 Hash Bash had a record 8000-15,000 attendees largely owing to the appearance of comedian Tommy Chong http://cheechandchong.com/ and was 2 hours long instead of the usual hour.[1]
