Mountain View, CA Public Conduct: Public Marijuana Use (2026)

100, part of the city's cannabis business registration chapter, sets three prohibited-acts categories. , "Cannabis use prohibited," states that cannabis may not be inhaled, smoked, eaten, ingested, vaped or otherwise used or consumed at a cannabis business's premises or in any public place, or in areas restricted under California Health and Safety Code Sec. 79, Business and Professions Code Sec. 26200, or other applicable state law, and requires a clearly posted notice at the business prohibiting smoking, ingesting and consuming cannabis. This local text does not stand alone: it cross-references and reinforces the state statutes that actually criminalize smoking or ingesting cannabis in most public places statewide, meaning Mountain View has not written its own separate criminal cannabis-in-public offense but has folded the state restriction into the conditions a registered cannabis business must enforce on-site and post notice of.

of Sec. " So the exposure for a person smoking cannabis on a sidewalk or in a park in Mountain View runs through state law (Health and Safety Code Sec. 79 and related Business and Professions Code provisions), while the exposure for a cannabis retailer that permits or fails to post against on-site public consumption runs through registration suspension or revocation administered by the police chief under Sec. 100 and the surrounding Chapter 9, Article IV framework adopted by Ord. No. 18 in 2018.
