The study highlights that cigarette butt pollution represents a significant but often overlooked source of both chemical contamination and microplastic pollution in aquatic environments.
Attitudes, Beliefs, and Behaviors about Cigarette-Butt Littering among College-Aged Adults in the United States
Researchers surveyed over 7,500 college-aged smokers across the United States and found that cigarette butt littering was most common among those who did not believe butts were harmful or considered litter, suggesting targeted education about butt toxicity and microplastic content could reduce this significant pollution source.
Time to kick the butt of the most common litter item in the world: Ban cigarette filters
Researchers argue that cigarette filters, made of cellulose acetate single-use plastic, offer no public health benefit while being the most littered item globally and a significant source of microplastics, toxic chemical leaching, and ecological harm.
The Hidden Threat of Microplastics in Traditional Cigarettes: A Narrative Review of Health and Environmental Risks
This review reveals that microplastics have been detected in 99% of cigarette filters, meaning smokers are inhaling and ingesting these particles with every cigarette. Microplastics have been found in the blood, lungs, placenta, and feces of the general population, but smokers face particularly high exposure. The improper disposal of cigarette butts also releases microplastics into the environment, making cigarettes a significant and overlooked source of microplastic pollution.
A Review of Environmental Pollution from the Use and Disposal of Cigarettes and Electronic Cigarettes: Contaminants, Sources, and Impacts
Researchers reviewed the environmental pollution caused by the use and disposal of cigarettes and electronic cigarettes, including their role as a source of microplastic contamination. Cigarette butts made of cellulose acetate are minimally degradable and represent a major source of both bulk plastic and microplastic pollution, particularly in aquatic ecosystems. The study documents that cigarette butt leachate and nicotine are toxic to a wide range of organisms from microbes to mammals.
Cigarette butts as a source of urban ecosystem pollution
Cigarette butts—the world's most littered item at ~4.5 trillion discarded annually—introduce over 4,000 chemicals into ecosystems and are a major source of microplastic fibers from cellulose acetate filters, with this review analyzing the toxicity of cigarette butt filtrate to aquatic and terrestrial organisms.
The unignorable ecological impact of cigarette butts in the ocean: an underestimated and under-researched concern
This opinion piece argues that cigarette butts — which contain plastic cellulose acetate filters that fragment into microplastics — are a significantly underestimated source of ocean plastic pollution. Billions of cigarette butts are discarded each year, and recognizing them as a major microplastic source is important for designing more effective litter-reduction policies.
Global cigarette butt contamination: a review
This review of 130 studies found that cigarette butts are everywhere in our environment—averaging about 1 butt for every 4 square meters globally—and they're especially common on beaches and in water where people swim and fish. These toxic cigarette filters break down into harmful chemicals and microplastics that can contaminate our water and food supply. The good news is that well-protected areas like national parks have nearly 10 times fewer cigarette butts, showing that proper management can reduce this health threat.
Microplastics from cigarette filters: Comparative effects on selected terrestrial and aquatic invertebrates
Researchers compared the effects of microplastics from smoked and unsmoked cigarette filters on both land and water invertebrates. Smoked filter microplastics were more toxic due to the added chemicals from tobacco smoke, causing reduced survival and reproduction in the test organisms. Since cigarette butts are one of the most littered items worldwide, this study shows they are a significant and underappreciated source of toxic microplastic pollution in the environment.
Koja je cijena pušenja? – Opasnosti za okoliš
This Croatian paper reviews the environmental hazards of cigarette butt litter, noting that approximately 80% of cigarette butts are discarded into the environment. Cigarette filters are made from cellulose acetate, a polymer that degrades slowly and leaches toxic chemicals into soil and water. The authors discuss biodegradable filter alternatives as a strategy to reduce plastic pollution from tobacco products.
A Comprehensive Study of Biodegradation of Cigarette Filters and Bidi Butts
This study assessed the biodegradation of cigarette filters and bidi butts using standardized international methods. Cigarette filters, made of cellulose acetate plastic, are among the most littered items globally and degrade slowly into microplastics. The research quantifies degradation rates to better understand the environmental persistence of this common litter.
Cigarette butts as a microfiber source with a microplastic level of concern
Researchers investigated whether cigarette butts are a significant source of microfiber pollution by analyzing smoked and unsmoked filters. They found that cigarette filters release large quantities of cellulose acetate microfibers, with smoked filters releasing even more than unsmoked ones due to degradation during use. The study identifies discarded cigarette butts as an overlooked but substantial contributor to microplastic pollution in the environment.
Microplastics and toxic leachate from littered cigarette butts threaten the environment, biodiversity, and human well-being
Observation of a butterfly drinking from a littered cigarette butt prompted this review of the environmental and health impacts of cigarette waste, highlighting cigarette filters as a major source of microplastic pollution and calling for sustainable mitigation measures from manufacturers and policymakers.
Fate of nanoplastics in the environment: Implication of the cigarette butts
