What You'll Learn
Cigarette smoke produces 10 times more air pollution than diesel car exhaust
Cigarette smoke produces ten times more air pollution than diesel car exhaust, according to a controlled experiment reported in Tobacco Control. The experiment, which was carried out in a private garage in a small mountain town in northern Italy, found that the combined particulate levels in the first hour after lighting the cigarettes were 830 ug/m3—ten times greater than the 88 ug/m3 recorded in the first hour after starting the diesel engine.
The environmental tobacco smoke particulate matter reached levels 15 times those measured outdoors, while the diesel engine exhaust doubled the particulate matter levels found outdoors at its peak. This is particularly concerning given that particulate matter is the most dangerous element of air pollution for human health.
The health dangers of cigarette smoke exposure are well-documented, with strong evidence linking it to cardiovascular disease. Epidemiological studies have also shown that passive smokers with excessive exposure to tobacco smoke environments have approximately 30% more risk factors for coronary artery disease compared to active smokers. In addition to the health risks, tobacco also poses a significant threat to the environment. Tobacco products are the most littered item on the planet, with cigarette butts making their way into oceans, rivers, sidewalks, parks, soil, and beaches. The filters contain microplastics and are the second-highest form of plastic pollution worldwide.
The tobacco industry also has a substantial carbon footprint, with the production, processing, and transportation of tobacco equivalent to one-fifth of the CO2 produced by the commercial airline industry annually. The industry's environmental impact is further exacerbated by deforestation, the use of fossil fuels, and the dumping or leaking of waste products into the natural environment.

Cigarette butts are the most littered item globally
Cigarette butts are the most littered item in the world, with around 4.5 trillion of them being tossed away each year. They are commonly found on streets, in parks, and on beaches, with researchers in Brazil collecting 4,300 cigarette butts from public sidewalks in the city of Guarujá, and researchers in India finding more than 17,000 pieces of tobacco product litter, including cigarette butts, in nine cities. The American non-smokers' rights lobbying group, ANR, reported that 1.69 billion pounds of butts ended up as toxic waste last year.
Cigarette butts are made up of two parts: a plastic filter and the remnants of the used tobacco. The leftover tobacco is biodegradable, but the plastic filters are made from cellulose acetate, a compound that eventually breaks down but never disappears. These filters are one of the main sources of microplastics in the environment, contributing to the build-up of plastic pollution. They also contain toxic chemicals that leach into the soil and water, causing serious environmental harm. The small size and low economic value of cigarette butts make them difficult to collect and manage, and their toxic chemical composition poses significant challenges to waste management systems.
The tobacco industry's environmental impact is significant, with a carbon footprint from production, processing, and transportation equivalent to one-fifth of the CO2 produced by the commercial airline industry annually, according to a WHO report. The report, "Tobacco: Poisoning Our Planet," highlights the presence of over 7,000 toxic chemicals in tobacco products, which leech into the environment when discarded. The cost of cleaning up this littered waste falls on taxpayers, with China spending approximately US$2.6 billion and India spending about US$766 million annually.
To address the environmental impact of cigarette butts, strategies such as innovative designs for biodegradability, improved waste collection techniques, and policy changes to induce behavioural changes in smokers and manufacturers are essential. Banning cigarette filters, implementing plain packaging, and holding the tobacco industry accountable for clearing up pollution are also recommended by researchers and organisations like WHO. Additionally, raising public awareness about the harmful effects of cigarette butt littering and encouraging proper disposal practices can help mitigate the issue.

Cigarette waste pollutes water, air and land
Cigarette waste is a significant contributor to pollution and has a detrimental impact on the environment, including water, air, and land.
Cigarettes are the most littered item globally, with cigarette butts being tossed on streets, beaches, and waterways. The filters contain plastic and toxic chemicals that leech into the environment, causing water and soil pollution. E-cigarettes also contribute to this issue as their waste contains metal, circuitry, disposable plastic cartridges, batteries, and toxic chemicals. These pollutants can have harmful effects on wildlife and ecosystems, leading to biodiversity losses.
Cigarette butt littering is a public nuisance and a health hazard. The waste contains over 7,000 toxic chemicals, which can mix with leaf litter and break down into microplastics and chemicals that flow into storm drains and pollute waterways. Cigarette filters are made from cellulose acetate, a type of plastic that only degrades under specific circumstances, such as when filters collect in sewage. This means that the plastic pollution from cigarette butts can persist for a long time in the environment.
The tobacco supply chain also poses serious environmental concerns, including deforestation, the use of fossil fuels, and the dumping or leaking of waste products into the natural environment. Tobacco production requires large amounts of water and farmland, which could otherwise be used to grow food for local communities. The industry's carbon footprint from production, processing, and transportation is significant, contributing to adverse climate change.
In addition to the environmental impact, cigarette smoking is a major cause of air pollution. Studies have shown that cigarette smoke produces up to 10 times more air pollution than diesel car exhaust. The particulate matter in cigarette smoke has been linked to various health issues, including cardiovascular diseases and lung cancer. Passive smokers are also at risk, with increased exposure to tobacco smoke leading to higher risk factors for certain health conditions.

Cigarette filters contain microplastics
Cigarettes are the most littered item in many countries, and tobacco doesn't just negatively impact the health of individuals, it also endangers the health of the environment. Cigarette butts are a significant contributor to plastic pollution, with roughly 4.5 trillion filters polluting oceans, rivers, sidewalks, parks, soil, and beaches annually. Cigarette filters contain microplastics, which are composed of cellulose acetate, a plastic that does not readily biodegrade. These microplastics can be dispersed in water, soil, and air, and due to their high absorption capabilities, they can collect and retain toxic pollutants, posing a potential danger to living organisms.
Cigarette filters are made from cellulose acetate, a plastic that is either enhanced with triacetate or blended with activated carbon. This material is designed to inhibit decomposition by the cellulase enzyme, allowing for frequent filter replacements. The presence of microplastics in cigarette filters has raised concerns among researchers, environmentalists, and politicians due to their potential eco-toxicity and impact on human health. Studies have examined the inflammatory effect of these microplastics on peripheral blood mononuclear cells, which are frequently used to study immune responses and the secretion of inflammatory cytokines.
The correct management of cigarette filter microplastics is an unsolved issue that requires urgent attention. While some municipalities have prohibited smoking in certain areas, such as beaches and parks, the disposal of cigarette waste remains a challenge. The cost of cleaning up littered tobacco products falls on taxpayers rather than the industry creating the problem. WHO has called for policy-makers to treat cigarette filters as single-use plastics and consider banning them to protect public health and the environment.
Additionally, e-cigarette waste contributes to the growing issue of electronic waste. E-cigarette cartridges discarded on streets can break down into microplastics and chemicals, polluting waterways and wildlife. E-cigarette waste contains metal, circuitry, disposable plastic cartridges, batteries, and toxic chemicals in e-liquids. While there are ways to safely dispose of e-cigarette cartridges, such as returning them to manufacturers for recycling, the lack of guidance and specific processes for disposal contributes to the environmental impact of the tobacco industry.

Tobacco production and consumption have serious environmental consequences
Tobacco products, including cigarettes, are the most littered item on the planet, with cigarette butts being the single most littered item. An estimated 766,571 metric tons of cigarette butts end up in the environment each year, polluting oceans, rivers, sidewalks, parks, soil, and beaches. Cigarette filters, which are made of plastic, are the second-highest form of plastic pollution worldwide. They contain microplastics and toxic chemicals that leech into the environment, causing hazardous effects on ecosystems. The cost of cleaning up this litter falls on taxpayers rather than the tobacco industry.
In addition to the environmental impact of tobacco waste, the production and consumption of tobacco also contribute to air pollution. Cigarette smoke produces particulate matter, which is the most dangerous element of air pollution for human health. A controlled experiment found that the air pollution emitted by cigarettes is ten times greater than that of diesel car exhaust. This fine particulate matter has been linked to cardiovascular diseases, including myocardial infarction, ischemia, and strokes.
Furthermore, tobacco growers are at risk of "green tobacco sickness" (GTS), an occupational illness caused by absorbing nicotine through the skin from contact with wet tobacco leaves. Symptoms of GTS include headaches, nausea, vomiting, weakness, dizziness, and abdominal cramps. Children, who make up a significant proportion of tobacco farming workforces, are especially vulnerable to GTS due to their smaller body size and lack of tolerance to nicotine.
