Cigarette pollution is a pressing issue that harms both the environment and human health. The tobacco industry's carbon footprint from production, processing, and transportation is significant, contributing to global warming. In addition, cigarette butts, made from plastic filters that don't biodegrade, are the most frequently littered item, polluting waterways and oceans and causing toxic effects on ecosystems. E-cigarettes also contribute to waste, with their short lifespans and plastic, electronic, and chemical components. The air pollution emitted by cigarettes is concerning, with studies suggesting it produces 10 times more pollution than diesel car exhaust, impacting cardiovascular health and increasing the risk of fatal coronary artery disease. Addressing cigarette pollution requires a multifaceted approach, including reduced tobacco use, proper disposal, and holding the tobacco industry accountable for its environmental impact.

What You'll Learn
Cigarette butts are the most littered item
Cigarette butts are often disposed of on streets, sidewalks, and other public areas, and may then be carried as runoff to drains, polluting rivers, beaches, and oceans. Cigarette filters are made from cellulose acetate, a plastic that only degrades under severe biological circumstances, such as when filters collect in sewage. In practice, cigarette butts tossed on streets and beaches do not biodegrade. Under optimal conditions, it can take at least nine months for a cigarette butt to degrade. The sun may break cigarette butts down, but only into smaller pieces of plastic waste that dilute into water or soil.
The plastic fibres in cigarette filters mean that cigarette butts are a significant contributor to plastic pollution. Cigarette filters contain microplastics and make up the second-highest form of plastic pollution worldwide. They also contain toxic chemicals that leach into the soil and water, such as arsenic and lead.
The tobacco industry has historically marketed filtered cigarettes as healthier, despite the overwhelming majority of research suggesting otherwise. The branding on littered cigarette butts could be used to hold the industry accountable for the pollution it creates. Strategies to reduce the hazardous effects of cigarette butt littering include introducing innovative designs to make them more biodegradable, improving waste collection techniques, and implementing policies that induce behavioural changes in smokers and manufacturers to reduce littering.

Cigarette waste is non-biodegradable
Cigarette butts are the most frequently littered item worldwide, with around 4.5 trillion cigarettes being littered each year. They are often disposed of on streets, sidewalks, and other public areas, and may then be carried as runoff to drains, polluting rivers, beaches, and oceans. Cigarette filters are made from cellulose acetate, a plastic that does not biodegrade. In practice, cigarette butts tossed onto streets and beaches do not biodegrade. While the sun may break down cigarette butts, this is only into smaller pieces of plastic waste, which then dilute into water or soil.
The plastic fibres in cigarettes are non-biodegradable, meaning they will not organically break down by the action of living organisms. Although cigarettes can gradually decompose depending on environmental conditions like rain and sun, this process is slow. A recent study found that a cigarette butt was only about 38% decomposed after two years. Cigarette butts that are not eaten by wildlife simply pile up on shorelines or at the bottom of bodies of water.
The tobacco industry's carbon footprint from production, processing, and transportation is equivalent to one-fifth of the CO2 produced by the commercial airline industry each year, contributing to global warming. The environmental impact of cigarette waste is further exacerbated by the presence of toxic chemicals in cigarette butts, which can contaminate water and poison fish and other wildlife.
The cost of cleaning up cigarette butts is also significant, with cities spending millions of dollars on cigarette clean-up efforts. In addition to the financial burden, cigarette litter also poses a health risk to the public. The WHO has called for steps to be taken to hold the tobacco industry accountable for the environmental destruction it is causing. Extended producer responsibility legislation has been implemented, making the tobacco industry responsible for clearing up the pollution it creates.

Cigarette smoke is 10 times more polluting than diesel exhaust
A controlled experiment reported in Tobacco Control found that cigarette smoke produces 10 times more air pollution than diesel car exhaust. The experiment was carried out in a private garage in a small mountain town in northern Italy, which has very low levels of particulate matter air pollution. A turbo diesel 2-litre engine was started and left idling for 30 minutes in the garage with the doors closed, after which the doors were left open for four hours. The car was fuelled with low-sulphur fuel. Three filter cigarettes were then lit up sequentially and left smouldering for a further 30 minutes. The combined particulate levels in the first hour after the engine had been started measured 88 ug/m3, while those recorded in the first hour after the cigarettes had been lit measured 830 ug/m3: 10 times greater. The diesel engine exhaust doubled the particulate matter levels found outdoors at its peak, but the environmental tobacco smoke particulate matter reached levels 15 times those measured outdoors.
The air pollution emitted by cigarettes is considered the most dangerous element of air pollution for health. Levels indoors can far exceed those outdoors because new engine models and lead-free fuels have cut the levels of particulate matter emissions from car exhausts. Cigarette smoke gives off a lot more respirable particulates, which can penetrate right into the alveoli in the lungs, where carcinogens do the most damage.
In addition to the health risks, cigarette butts are the most frequently littered item in US beaches and waterways. Cigarette filters are made from cellulose acetate, a plastic that does not biodegrade. The sun may break cigarette butts down, but only into smaller pieces of waste that dilute into water or soil. The actual number of cigarette butts polluting the environment is closer to 9.7 billion, polluting roadways and waterways combined, along with 392 million pieces of other tobacco-related products and packaging, making up nearly 20% of all US litter.
The tobacco industry's carbon footprint from production, processing, and transporting tobacco is equivalent to one-fifth of the CO2 produced by the commercial airline industry each year, further contributing to global warming.

Cigarette production and consumption harm the environment
Cigarette production and consumption have a significantly harmful impact on the environment. The tobacco industry's carbon footprint from production, processing, and transportation is equivalent to one-fifth of the CO2 produced by the commercial airline industry annually, contributing to global warming. The growing of tobacco plants, the disposal of cigarette butts, and the use of single-use plastic products in e-cigarettes all contribute to environmental degradation.
Tobacco agriculture generates greenhouse gases, including CO2 from diesel-powered farm machinery and NO2 from fertilizers. The production and transportation of cigarettes also contribute to CO2 emissions. The carbon absorbed by tobacco leaves during their growth is returned to the atmosphere when they are smoked, but the process of smoking itself produces air pollution. A controlled experiment reported in Tobacco Control found that the air pollution emitted by cigarettes is ten times greater than diesel car exhaust. The fine particulate matter produced by cigarettes is the most dangerous element of air pollution for human health, as it can cause cardiovascular diseases such as myocardial infarction, ischemia, and strokes.
Cigarette butts, made primarily of plastic filters that do not biodegrade, are the most frequently littered item in U.S. beaches and waterways. They are often disposed of on streets and sidewalks, eventually making their way into drains, rivers, and oceans. The sun may break down cigarette butts, but only into smaller pieces of plastic waste that pollute the water and soil. This plastic pollution has hazardous effects on ecosystems, wildlife, and water quality. The actual number of cigarette butts polluting the environment is estimated to be around 9.7 billion, with 79% of smokers acknowledging that they consider cigarette butts to be litter.
The e-cigarette waste from disposable e-cigarettes, which contain plastic, electronic, and chemical waste, is an emerging issue as these products increase in popularity. E-cigarette cartridges discarded on streets can break down into microplastics and chemicals, polluting waterways and wildlife. While there are ways to safely dispose of e-cigarette waste, such as returning them to manufacturers for recycling, the lack of mandatory guidelines and transparent reporting of environmental data by tobacco companies makes it challenging to hold them accountable for their environmental impact.

Cigarette pollution causes cardiovascular disease
Cigarette pollution is a significant contributor to cardiovascular disease, with the air pollution emitted by cigarettes being approximately 10 times greater than diesel car exhaust. This fine particulate matter, which is the most dangerous element of air pollution for health, infiltrates indoor spaces and can have detrimental effects on cardiovascular health.
Cigarette smoke contains numerous toxic chemicals, and when released into the environment, these toxins contribute to the development of cardiovascular disease. The World Health Organization (WHO) has identified air pollution as the foremost environmental risk factor, accounting for about one-ninth of all global deaths. Among these, cigarette smoking is a leading cause of fetal coronary artery disease and myocardial infarction.
The toxins in cigarette smoke have been linked to lipid modification, inflammation, and vasomotor dysfunction, which are integral components of atherosclerosis development. This can lead to fatal coronary artery disease and increase the risk of myocardial infarction. The impact of cigarette pollution on cardiovascular health is comparable to that of pulmonary problems, with cigarette smoking being a significant cause of lung cancer, heart disease, and stroke.
In addition to direct smokers, passive smokers or those exposed to secondhand smoke are also at risk. Secondhand smoke exposure increases the likelihood of coronary heart disease and stroke, with non-smokers exposed to secondhand smoke having a 25% to 30% higher risk of developing heart disease. Even short-term exposure to secondhand smoke can damage blood vessels and increase the risk of a heart attack.
Quitting smoking is crucial to reducing the risk of cardiovascular disease. Studies have shown that within one to two years of quitting, the risk of a heart attack decreases significantly, and the risk continues to diminish over time. Therefore, it is essential to address cigarette pollution and encourage smoking cessation to mitigate the harmful impacts of cigarette pollution on cardiovascular health.
