Summary

Lee's Summit bars consuming adult-use marijuana in any public place, sidewalks, streets, parks, schools and businesses included, and backs it with a civil fine capped at $100 under a companion penalty section rather than criminal jail time.

A.No person shall consume adult use marijuana in a public place.B.As used in this section only, "public place" means the same as the term defined by applicable Missouri Regulation, as amended, which is any public or private property, or portion of public or private property, that is open to the general public, including, but not limited to, sidewalks, streets, bridges, parks, schools, and businesses. "Public place" shall not include:1.The residence of the person consuming adult use marijuana or the residence of another person when the person in control of that property has consented to the consumption of adult use marijuana; or2.An area licensed by the authorities having jurisdiction over the licensing and/or permitting of said activity.

Full Breakdown

Sec. 17-246 flatly bans consuming adult-use marijuana in a 'public place,' a term the ordinance ties directly to the definition used in state marijuana regulations: any public or private property, or portion of it, that is open to the general public, expressly including sidewalks, streets, bridges, parks, schools and businesses. The exceptions are narrow and mirror the definitions used across the chapter's marijuana provisions (Secs. 17-242 through 17-248): a person's own residence, another person's residence where the occupant has consented to the consumption, and any area specifically licensed by the authority with jurisdiction over that licensing or permitting, such as a state-licensed consumption lounge.

Enforcement sits alongside Sec. 17-245's ban on cultivating more than three ounces of visible or unlocked marijuana at a residence and Sec. 17-244's parallel ban on public medical-marijuana consumption, all adopted together by Ordinance No. 9594 in January 2023 to implement Article XIV of the Missouri Constitution at the local level. The penalty for smoking marijuana in public is set in the companion penalties section, Sec. 17-248(C), as a civil infraction rather than a criminal charge, consistent with how Missouri's constitutional marijuana amendment treats low-level violations.

Violations & Fines

Sec. 17-248(C) makes a person who smokes marijuana in a public place, in violation of Sec. 17-246, subject to a civil penalty not exceeding $100, authorized under Article XIV of the Missouri Constitution, rather than the Code's general criminal fine and jail exposure that applies to most Chapter 17 offenses.

Frequently Asked Questions

Is smoking marijuana in a Lee's Summit park a criminal offense?
No. Sec. 17-246 bans it, but Sec. 17-248(C) makes the penalty a civil infraction capped at $100, not a criminal charge, which is consistent with how Article XIV of the Missouri Constitution treats minor adult-use marijuana violations statewide.
Can you consume marijuana on your own porch in Lee's Summit?
Yes. Sec. 17-246(B) excludes a person's own residence, or another person's residence where the occupant has consented to the consumption, from the definition of 'public place,' so home use, including a private yard or porch, is not covered by the ban.
Does Lee's Summit's public marijuana ban cover licensed consumption areas?
No. Sec. 17-246(B)(2) excludes any area licensed by the authority having jurisdiction over the licensing or permitting of that activity, meaning a state-authorized consumption lounge or similar licensed venue falls outside the public-place definition.
