Time to kick the butt of the most common litter item in the world: Ban cigarette filters
AI summary Read the abstract
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.
Cigarette filters offer no public health benefits, are single-use plastics (cellulose acetate) and are routinely littered. Filters account for a significant proportion of plastic litter worldwide, requiring considerable public funds to remove, and are a source of microplastics. Used cigarette filters can leech toxic chemicals and pose an ecological risk to both terrestrial and aquatic ecosystems. Bottom-up measures, such as focusing on consumer behaviour, are ineffective and we need to impose top-down solutions (i.e., bans) if we are to reduce the prevalence of this number one litter item. Banning filters offers numerous ecological, socioeconomic, and public health benefits.

AI summary Read the abstract
Researchers conducted a randomized cross-over trial in 29 smokers switching between filtered and unfiltered cigarettes and found no significant difference in urinary cotinine or NNAL nitrosamine biomarkers, suggesting that banning cellulose acetate filters—the most common plastic litter item—would reduce environmental microplastic pollution without meaningfully increasing health risk to smokers.
