Residents of Rock Hill, Missouri are suing a cannabis company over what they claim is a “skunky” smell that emanates from the business’s processing facility. The lawsuit contends that “noxious odors” released from New Growth Horizon’s Proper Brands facility invades the plaintiffs’ properties “causing property damage through private nuisance, public nuisance, and negligence.”
The facility includes both cultivation of cannabis plants and extraction for resin, live rosin, and distillates used in edible and vape products.
The lawsuit contends that the owners of the Proper Brands facility have “failed to develop, implement, operate, and/or maintain adequate odor mitigating strategies, processes, technologies, and equipment to control its odorous emissions from the Facility and prevent those odors and emissions from invading the homes and properties.”
According to the plaintiffs, the facility “has been the subject of frequent complaints from residents” neighboring the facility and that in April 2025, city officials released a statement saying that they were “aware of the issues with the odor coming from the marijuana production facility,” take the “issue seriously,” and were “working with the compliance officer for the facility and the Missouri Department of Health and Senior Services to facilitate more effective odor mitigation solutions.”
