Recent policy changes in a number of states legalizing cannabis for medical and/or recreational use suggest a shift in societal attitudes and perceptions around cannabis. University Health Services takes a harm reduction approach to all substance use, including cannabis.

See this Cannabis handout for more information.

Policy and Legality

In November 2016, California voters passed Proposition 64 legalizing recreational use among people over the age of 21. However, because federal law still prohibits the use, distribution and possession of cannabis, it remains prohibited on all university property and at all university events, except for approved academic research. See UC guidance on use and possession of cannabis on UC property for more information.

In addition, smoking cannabis or any product on university property, is prohibited by UC policy per University of California – Policy on Smoke and Tobacco Free Environment
