Summary

Researchers reviewed evidence on whether cellulose acetate cigarette filters provide any protective health benefit and their environmental impact as plastic waste. The study found persistent concerns that filters offer limited health protection while contributing significantly to environmental pollution, as discarded cigarette butts made from this plant-based plastic are a major source of toxic litter.

The World No Tobacco Day 2022 theme emphasised tobacco's adverse environmental effects, including through agriculture, manufacturing, distribution, use and the disposal of tobacco product waste. A main concern regarding this toxic waste is the cigarette filter, which is attached to nearly all commercial cigarettes and is predominantly made from a plant-based plastic (cellulose acetate). Laboratory studies have demonstrated the chemical toxicity of discarded cigarette butts, and there is growing public concern regarding environmental plastic pollution resulting from single-use cellulose acetate filters. Important considerations are whether the filter has any protective role against the harms of smoking and whether it should be regulated as a plastic environmental pollutant. There is persistent misunderstanding among smokers and policy makers about the implied value of the cigarette filter. The cellulose acetate filter is simply a marketing tool that encourages smoking initiation and reduces intentions to quit smoking. This is because it makes smoking easier and implies added safety through the presumed filtration of inhaled smoke. The sale of filtered cigarettes should be prohibited to protect public health and the environment.

Protecting public health and the environment: towards a general ban on cellulose acetate cigarette filters in the European Union

This paper reviewed evidence on cellulose acetate cigarette filters, finding that they encourage smoking, are inhaled more deeply, and are a significant source of persistent plastic pollution, supporting calls for a general ban on cellulose acetate filters.

Tiny but Deadly: a Threat to Environment

This study quantified toxic metals leaching from discarded cigarette butts — the most common form of plastic litter — finding that both the filter and the whole butt release metals into water. Cigarette filters are made from cellulose acetate plastic and represent a poorly recognized source of chemical pollution in the environment.

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 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.

Review on Recycling of Microplastics in Cigarette Butts

This review examined the problem of cigarette butt waste, noting that cellulose acetate filters take approximately 10 years to degrade and represent a globally pervasive source of microplastic pollution. The authors surveyed recycling approaches for cigarette butts including fiber recovery and use in construction materials.
