Plymouth, MN Public Conduct: Public Marijuana Use (2026)

Section 970 of the Plymouth City Code, adopted by Ordinance No. 2023-14 in September 2023 and amended by Ordinance No. 2024-25 in November 2024, bars smoking cannabis or hemp in a public place anywhere in the City. Section 970.01 defines 'Smoking' to include inhaling, exhaling, burning or carrying any lighted or heated cigar, cigarette, pipe or other lighted or heated product intended for inhalation, and it expressly folds in electronic delivery devices such as vape pens, e-cigarettes and tank systems, so vaping cannabis in public is covered along with combustible smoking. 'Public place' is defined as any property owned, leased, or controlled by a governmental unit, which reaches City parks, sidewalks, trails and municipal buildings.

The definition carves out three settings where the ban does not apply: a private residence, including its curtilage or yard; private property not generally accessible to the public, unless the property owner has strictly prohibited cannabis consumption there; and the premises of an establishment or event specifically licensed to permit on-site consumption. Because 'Cannabis' and 'Hemp' are defined by cross-reference to the City's zoning definitions at § 21005.02, the same terms used to regulate cannabis businesses under the City's licensing chapter carry over to this public-use ban. A violation of § 970.02 is a petty misdemeanor under § 970.03, the lowest tier of Minnesota criminal offense, typically resolved by a citation rather than a court appearance.
