Baltimore Is Suing Big Tobacco Over Cigarette Litter — And It’s a First-of-its-Kind Case

In November 2022, Baltimore City filed what may be the first lawsuit of its kind anywhere in the country. Instead of suing tobacco companies over health injuries to smokers, Baltimore is suing them for the cost of cleaning up the mess their products leave behind — specifically, cigarette filters. The city says it spends more than $5 million every year picking up discarded cigarette butts from streets, parks, and waterways.

The case has survived multiple attempts by tobacco companies to get it thrown out. A judge allowed it to move forward, and the most recent twist came in March 2026, when the companies raised a new defense: claiming that a 1998 nationwide settlement agreement prevents Baltimore from suing them at all.

What’s in a Cigarette Filter

Most cigarette filters are made from cellulose acetate — a type of plastic. Despite what many people believe, they are not biodegradable. When discarded, cigarette butts break into microplastics and leach toxic chemicals (including arsenic, lead, and nicotine) into soil and water.

Baltimore argues that tobacco companies have known this for decades but marketed filters as a health feature — implying they made cigarettes safer — while never disclosing that the filters would become a lasting environmental pollutant. The city says that design choice, and that marketing, created a problem cities are now stuck paying for.

What Happened in Court

The tobacco companies named as defendants include Philip Morris USA, Altria Group, R.J. Reynolds Tobacco Company, British American Tobacco, and Liggett Group. Their first move was to argue the case should be in federal court, not state court. Baltimore fought back, and in January 2024, the case was sent back to state court — a win for the city.

In July 2025, a Baltimore Circuit Court judge let the case move forward, rejecting key parts of the tobacco companies’ motion to dismiss. The trespass claim was dismissed, but three claims survived: public nuisance, strict liability failure to warn, and negligent failure to warn.

In March 2026, the companies came back with a new argument: that the 1998 Tobacco Master Settlement Agreement — the nationwide deal that resolved states’ health cost claims against tobacco companies and generated billions in payments over the years — shields them from Baltimore’s pollution claims. Baltimore counters that the MSA only covered health-related costs, not environmental cleanup. That argument is now before the court.

Why This Case Matters Beyond Baltimore

Cigarette litter is a problem in virtually every American city. If Baltimore’s lawsuit succeeds, other municipalities could use it as a blueprint to hold tobacco companies accountable for filter cleanup costs. Cities and counties across the country spend public money picking up cigarette butts every year — money that Baltimore argues should come from the companies that made, sold, and profited from the product.

On the other side, if the tobacco companies win — particularly on their Master Settlement Agreement argument — the door to environmental cleanup claims would largely close. That outcome would make it much harder for any city to pursue a similar case in the future.

Environmental advocates, public health groups, and municipal governments across the country are watching closely.

Does This Affect Smokers with Health Cases?

This is important to understand: the Baltimore case is about environmental cleanup costs paid by the city, not about health injuries to individual smokers.

If you or a family member developed lung cancer, COPD, throat cancer, or another serious illness from smoking, that is an entirely different type of case — and those cases are still being filed and actively pursued. Florida, in particular, has a long history of tobacco cases going to trial, and individual smokers continue to bring and win these cases.

The Baltimore lawsuit doesn’t change anything about smokers’ rights to pursue their own cases. It is a separate track, pursued by a city government over a separate harm.
