The environmental impact of cigarette pollution is a growing concern. While the health risks associated with smoking are well-known, the impact of cigarette production and consumption on the environment is also significant. With 1.1 billion smokers worldwide, the cigarette is the most littered item on the planet, and the pollution caused by cigarette butts, toxic chemicals, and waste is an increasing problem. The tobacco industry is responsible for substantial land use, water consumption, and carbon emissions, and the environmental impact of cigarette smoking is felt at every stage of the process, from production to disposal.

Cigarette butts are the most littered item, polluting waterways and soil
Cigarette butts are the most littered item worldwide, polluting waterways and soil. They account for about 4.5 trillion of the cigarettes littered each year, making them the top littered item on the planet. This is particularly harmful because cigarette butts contain filters made from cellulose acetate, a plastic that does not readily biodegrade. Instead, these filters break down into smaller pieces of plastic that pollute the soil and water.
Cigarette butts are commonly disposed of on streets, sidewalks, and other public areas, where they are washed into drains and ultimately end up in rivers, oceans, and beaches. In the United States, cigarette butts are the most frequently found item on beaches and in waterways. A study in Brazil collected 4,300 cigarette butts from public sidewalks in the coastal city of Guarujá, demonstrating the severe pollution caused by these littered butts.
The environmental impact of cigarette butts is significant due to the presence of toxic chemicals in the filters. These chemicals, including arsenic and lead, leach into the soil and water, contaminating the environment and posing risks to human health. The World Health Organization (WHO) estimates that tobacco product litter accounts for 25% to 40% of all global litter, with cigarette butts being the primary contributor.
The tobacco industry has long marketed filtered cigarettes as a healthier alternative, despite research indicating otherwise. The costs of cleaning up this litter fall on taxpayers rather than the industry. Additionally, the environmental impact of tobacco extends beyond littering. Tobacco farming contributes to deforestation, soil degradation, and increased greenhouse gas emissions, further exacerbating the environmental harm caused by cigarette waste.

Cigarette filters contain microplastics, which are the second-highest form of plastic pollution
Cigarette filters are made from cellulose acetate, a type of plastic that does not readily biodegrade. These filters are a significant source of pollution, as they are often littered and can end up in our oceans, rivers, and soil. Cigarette butts are the most frequently found form of debris in streets, parks, and beaches, and they are the second-highest form of plastic pollution worldwide.
Cigarette filters are designed to be replaced frequently, contributing to the vast amount of solid waste generated annually. Among this waste, cigarette filters stand out as the most common type of litter found in natural environments, with approximately 6.5 trillion cigarettes manufactured and consumed globally each year. This number is projected to increase by 50% by 2025, leading to the creation of 1.2 million tons of waste.
The microplastics in cigarette butts are composed of thousands of tiny plastic fibres that are too small to clean up and can disperse widely. These fibres have a high absorption capacity, allowing them to collect and retain toxic pollutants. As a result, they pose a potential danger to living organisms, including humans. The toxic chemicals in cigarette butts can leach into our food, water, and air, threatening the health of all.
The tobacco industry has been accused of deliberately misleading consumers about the environmental impact of their products. Despite knowing that cigarette filters are made from non-biodegradable microplastics, they have denied the existence of any such issue. The costs of cleaning up littered tobacco products, estimated to be in the billions of dollars, are borne by taxpayers rather than the industry responsible.

Cigarette production uses more than 22 billion tonnes of water
Cigarette pollution has a significant impact on the environment. Tobacco production uses more than 22 billion tonnes of water, contributing to water scarcity and endangering the health of the environment. The water used in tobacco production often comes from low-and-middle-income countries, where it is desperately needed for food production. The energy-intensive curing of tobacco leaves, or "processing", uses coal or wood burning, contributing to greenhouse gas emissions and deforestation.
The impact of cigarette pollution extends beyond water usage. Tobacco is the most littered item globally, with cigarette butts polluting waterways, oceans, and beaches. These butts are made of plastic filters that do not biodegrade, leading to the accumulation of waste in natural environments. The tobacco industry is responsible for the loss of 600 million trees and 200,000 hectares of land annually, contributing to soil degradation and failing yields. The burning of tobacco during processing and by consumers generates air pollutants and increases greenhouse gas levels.
The environmental impact of cigarettes is further exacerbated by their toxic chemicals and heavy metals. When burned, cigarettes release over 7,000 chemicals, including at least 69 known carcinogens and various toxic substances. These chemicals leech into the environment, endangering wildlife and public health. The solid and wastewater produced by the tobacco industry, amounting to 25 megatons and 55 megatons respectively, contribute to the pollution of water sources.
The production and consumption of cigarettes have a detrimental effect on the environment, particularly regarding water usage and pollution. The water-intensive nature of tobacco production, coupled with the pollution caused by cigarette waste, poses a significant threat to natural water sources and the health of ecosystems and communities that rely on them. The tobacco industry's environmental footprint underscores the urgency of curbing tobacco use and addressing the detrimental effects on water resources, wildlife, and public health.

Tobacco farming causes deforestation, soil degradation, and water depletion
Tobacco farming has a significant environmental impact, contributing to deforestation, soil degradation, and water depletion.
Firstly, tobacco farming causes deforestation, the purposeful clearing of forested land. Tobacco farming accounts for about 5% of global deforestation, with approximately 200,000 hectares of land, or just over seven million acres, cleared annually for tobacco agriculture and curing. This figure is equivalent to about two-thirds of Yosemite National Park. Deforestation destroys forests that act as the Earth's lungs, releasing stored carbon back into the atmosphere as carbon dioxide, contributing to climate change and causing environmental damage. It also threatens biodiversity, leaving the soil vulnerable to erosion and increasing the risk of fires.
Secondly, tobacco farming leads to soil degradation. Tobacco plants are resource-intensive to grow, requiring the use of harsh pesticides, fertilizers, and growth regulators that damage the soil. These chemicals run off into nearby water sources, contaminating lakes, rivers, and drinking water. Additionally, tobacco crops deplete soil nutrients by taking up more nitrogen, phosphorus, and potassium than other major crops, further decreasing soil fertility.
Finally, tobacco farming contributes to water depletion. Tobacco cultivation requires massive amounts of water, with the crop needing up to eight times more water than other crops like tomatoes or potatoes. Each year, about 15 million Olympic-sized swimming pools' worth of water are used for tobacco production—that's about a gallon of water per cigarette.
The environmental impact of tobacco farming extends beyond these immediate effects, polluting throughout every step of production and affecting the quality of land and water while contributing to climate change through greenhouse gas emissions.

Cigarette smoke produces 10 times more air pollution than diesel car exhaust
The experiment involved leaving a turbo diesel 2-litre engine idling for 30 minutes in a closed garage, 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 another 30 minutes. A portable analyser took readings every two minutes during the experiments.
The combined particulate levels in the first hour after the engine was started measured 88 ug/m3. In the first hour after the cigarettes were lit, the levels measured 830 ug/m3: 10 times greater. The diesel engine exhaust doubled the particulate matter levels found outdoors at its peak; the environmental tobacco smoke particulate matter reached levels 15 times those measured outdoors.
The experiment highlights the significant impact of cigarette smoke on air pollution, which is further exacerbated by the fact that cigarettes are the most littered item globally. Cigarette butts, which contain toxic chemicals, heavy metals, and residual nicotine, pollute waterways and soil. The filters, made from cellulose acetate, are a form of single-use plastic that does not readily biodegrade. In addition, tobacco farming contributes to deforestation, soil degradation, and increased greenhouse gas levels.

Frequently asked questions
It is estimated that 4.5 trillion cigarette filters pollute our oceans each year.
Cigarette production has increased from six trillion cigarettes per year to a predicted nine trillion by 2025. This will result in more agricultural land use, water and fossil fuel depletion, and increased CO2 emissions.
According to one experiment, cigarette smoke produces 10 times more air pollution than diesel car exhaust. However, it has also been argued that smokers live 10 years less than non-smokers on average, and that if they didn't smoke, they would generate much more CO2 through driving, using electricity, and buying things.
