Full Breakdown

California Health & Safety Code 11362.3 bans cannabis consumption in public places, anywhere tobacco smoking is prohibited, and within 1,000 feet of schools or daycare while children are present. Tuolumne County reinforces the ban on county property. Vehicle Code 23222(b) makes it an infraction for any driver or passenger to consume cannabis in a moving or parked vehicle on a highway. Twain Harte's Highway 108 corridor and Stanislaus National Forest trails are public places under these rules, and Cal Fire seasonal restrictions further bar smoking of any kind during fire season. Licensed cannabis retailers cannot operate in Tuolumne County under the local commercial cannabis ban.

Violations & Fines

Public cannabis use draws infractions, vehicle searches if the driver is impaired, and federal trespass tickets on national forest land.

Frequently Asked Questions

Can I smoke cannabis at a campsite?
Possibly, on private campsites where smoking is allowed and outside fire restrictions. National forest sites generally treat it as a public place where consumption is prohibited.
What about edibles in a park?
Public consumption rules apply to all forms, including edibles. Officers rarely cite obvious edible use, but it remains an infraction in public places.
