Warren, MI Public Conduct: Public Marijuana Use (2026)

26421 et seq. Sec. 21-85, titled 'Consumption or use by qualifying a patient,' prohibits a person who holds a lawful registry identification card as a qualifying patient from consuming or using marihuana in three settings: any public place; a common area of a hotel, motel, apartment building, condominium complex, or other business establishment, which the section spells out to include driveways, entrance areas, and parking lots open to the public or to other residents and guests; and any hotel, motel, apartment building, rental dwelling, or similar facility where the owner or property manager has separately prohibited marihuana growth, cultivation, manufacture, or transfer.

The article's own punishment clause, Sec. 21-86, ties its specific misdemeanor penalty to violations of the growing and processing rules in Sec. 21-83, not to the public consumption ban in Sec. 21-85, so a violation of the consumption ban falls back on the city's general penalty provision, Sec. 1-8: if an ordinance does not specify its own punishment, a violator faces a fine of up to $500, imprisonment for up to ninety days, and up to $1,000 in court costs, and each day the violation continues counts as a new, separate offense. The article works alongside Sec. 5's broader marihuana business and recreational-use licensing rules.
