Summary

In Southborough, Chapter 51 bans smoking, ingesting or otherwise using marijuana or THC on streets, sidewalks, parks, playgrounds, school grounds, parking lots, Town property, passenger conveyances and any place accessible to the public. Any police officer can enforce it with a $300 fine for each offense, on top of any state civil penalty.

No person shall smoke, ingest, or otherwise use or consume marijuana or tetrahydrocannabinol (as defined in MGL c. 94C, § 1 , as amended) while in or upon any street, sidewalk, public way, footway, passageway, stairs, bridge, park, playground, beach, recreation area, boat landing, public building, schoolhouse, school grounds, cemetery, parking lot, or any area owned by or under the control of the Town; or in or upon any bus or other passenger conveyance operated by a common carrier; or in any place accessible to the public. ... This bylaw may be enforced through any lawful means in law or in equity, including, but not limited to, enforcement by criminal indictment or complaint pursuant to MGL c. 40, § 21 , or by noncriminal disposition pursuant to MGL c. 40, § 21D , by any police officer. The fine for violation of this bylaw shall be $300 for each offense.

Full Breakdown

Chapter 51 was adopted by Town Meeting on 9-29-2009 (Special Town Meeting, Art. 10) and governs where marijuana and tetrahydrocannabinol can be used. Its general references point readers to Chapter 50 on alcoholic beverages and Chapter 131 on peace and good order.

Section 51-1 lists the covered locations one by one: any street, sidewalk, public way, footway, passageway, stairs, bridge, park, playground, beach, recreation area, boat landing, public building, schoolhouse, school grounds, cemetery, parking lot, or any area owned by or under the control of the Town. It also covers any bus or other passenger conveyance operated by a common carrier, and it closes with a catch-all: any place accessible to the public. That closing phrase extends the ban beyond the listed Town locations.

The verbs are broad. No person can smoke, ingest, or otherwise use or consume the substance, so the rule is not limited to smoking. Marijuana and tetrahydrocannabinol take their meaning from MGL c. 94C, § 1, as amended, which ties the local definition to the state controlled-substances statute.

Section 51-2 gives the Town several enforcement routes. The bylaw can be enforced through any lawful means in law or in equity, including enforcement by criminal indictment or complaint pursuant to MGL c. 40, § 21, or by noncriminal disposition pursuant to MGL c. 40, § 21D, by any police officer. The fine for violation is $300 for each offense. Section 51-2 adds that any penalty imposed under the bylaw is in addition to any civil penalty imposed under MGL c. 94C, § 32L, so the local fine does not replace the state penalty.

Violations & Fines

The fine for violating Chapter 51 is $300 for each offense (§ 51-2). Any police officer can proceed by criminal complaint under MGL c. 40, § 21 or by noncriminal disposition under MGL c. 40, § 21D. Any penalty imposed under the bylaw is in addition to the civil penalty under MGL c. 94C, § 32L, so a person can face both the local fine and the state penalty.

Frequently Asked Questions

Can I smoke marijuana in a Southborough park?
No. Section 51-1 bans smoking, ingesting, or otherwise using or consuming marijuana or tetrahydrocannabinol in or upon any park, playground, beach, recreation area or boat landing. It also covers any area owned by or under the control of the Town. The fine is $300 for each offense under § 51-2.
How much is the fine for public marijuana use in Southborough?
The fine is $300 for each offense under § 51-2. A police officer can issue it through noncriminal disposition under MGL c. 40, § 21D, or bring a criminal complaint under MGL c. 40, § 21. The bylaw penalty is in addition to any civil penalty imposed under MGL c. 94C, § 32L.
Does the bylaw cover edibles and other forms, not just smoking?
Yes. Section 51-1 prohibits a person from smoking, ingesting, or otherwise using or consuming marijuana or tetrahydrocannabinol. Both substances are defined by reference to MGL c. 94C, § 1, as amended. The act of ingesting is named separately from smoking, so the prohibition reaches more than smoked use in the listed places.
Does the ban cover parking lots and places that are not Town property?
Yes on both counts. Section 51-1 lists parking lots by name and also covers any area owned by or under the control of the Town. The final clause extends the ban to any place accessible to the public, and the section separately covers any bus or other passenger conveyance operated by a common carrier.
