Cigarettes: Hidden Polluters Of Our Environment

Cigarette smoke produces 10 times more air pollution than diesel car exhaust, according to a controlled experiment reported in Tobacco Control. The environmental costs of tobacco production and consumption are significant, with the industry impacting natural resources and vulnerable ecosystems. The tobacco supply chain involves deforestation, the use of fossil fuels, and the dumping of waste products. The burning of cigarettes creates over 7,000 chemicals, with at least 69 known to cause cancer and many being poisonous. Cigarette butts are also a major source of pollution, with cellulose acetate filters taking at least nine months to degrade and often ending up as the most prominently littered item on roadways, waterways, and beaches. The tobacco industry's carbon footprint from production, processing, and transport is equivalent to one-fifth of the CO2 produced by commercial airlines annually.

Cigarette butts are the most common item of litter, polluting waterways and soil

Cigarette butts are frequently found in the environment and account for a large portion of the world's litter. According to the International Coastal Cleanup report, based on data from over 100 countries, cigarette butts were the most littered items along the beach, with Ghana, Canada, and Chile being the top contributors. The widespread littering of cigarette butts is due to their wide consumption globally. For instance, 33% of the cigarettes produced in the US are littered in the environment, and in Australia, cigarette butts were found to be 91.5% of the miscellaneous waste category.

Cigarette butts are not just unsightly, but they also release harmful chemicals such as arsenic, lead, and nicotine into the environment. These toxic chemicals can remain in the environment for many years beyond the life of the cigarette butt itself. Cigarette waste pollutes water, air, and land, with over 7000 toxic chemicals leeching into the environment when cigarettes are discarded.

The environmental costs of tobacco production and consumption have not been extensively studied. However, it is clear that the tobacco industry is having a significant effect on the planet's natural resources. The World Health Organization (WHO) has raised alarms about the tobacco industry's environmental impact, calling for steps to hold the industry accountable for the destruction it is causing.

Cigarette filters are made from plastic and contain toxic chemicals

Cigarette butts are the most littered item worldwide. They are often discarded on streets, sidewalks, and other public areas, and end up in drains, rivers, beaches, oceans, and parks. Cigarette filters are made from cellulose acetate, a type of plastic that takes up to 10 years to decompose, and they contain toxic chemicals and microplastics that leech into the environment.

Cigarette filters are made from plastic, specifically cellulose acetate, which is a plastic that can take up to a decade to decompose. This means that when cigarette butts are discarded, they can persist in the environment for many years, releasing toxic chemicals and microplastics that can pollute waterways and harm wildlife.

The tobacco industry has long marketed cigarette filters as a way to reduce the health risks associated with smoking, suggesting that filters can block toxins and reduce the harm caused by cigarettes. However, research has shown that filters may actually increase the harm by enabling smokers to inhale smoke more deeply into their lungs. In addition, toxic fibres from the filters can be inhaled or ingested by smokers.

The environmental impact of cigarette filters is significant. Cigarette butts are the most commonly littered item globally, and they contain plastic filters that contribute to plastic pollution. The World Health Organization (WHO) has raised alarms about the environmental impact of the tobacco industry, noting that cigarette filters contain over 7000 toxic chemicals that leech into the environment when discarded.

The problem of cigarette filter pollution has been recognized by some governments and organizations. Countries like France and Spain and cities like San Francisco have implemented "extended producer responsibility legislation," which makes the tobacco industry responsible for cleaning up the pollution created by cigarette waste. The European Union is also taking steps to address this issue, with new rules requiring the tobacco industry to fund the cleaning up of cigarette stubs as part of an initiative to reduce single-use plastic items.

Tobacco growth and cultivation cause deforestation

Cigarette smoke produces ten times more air pollution than diesel car exhaust, according to a controlled experiment reported in Tobacco Control. The experiment found that the particulate levels in the first hour after lighting cigarettes were 830 ug/m3, ten times greater than the levels recorded after a diesel car had been left idling in a garage for 30 minutes.

However, the impact of cigarettes on the environment begins long before they are ever lit. Tobacco growth and cultivation cause deforestation, particularly in low- and middle-income countries (LMICs). In the early 2000s, it was estimated that tobacco farming was responsible for 4% of global deforestation, although this figure was much higher in certain countries, such as China (18%), Zimbabwe (20%), Malawi (26%), and Bangladesh (>30%). Tobacco farming has been linked to deforestation since the mid-1970s, and the problem has only escalated since then.

Tobacco cultivation requires a significant amount of land, and farmers often seek to expand their plots by clearing adjacent forested land, usually by burning it. The soil is often not suitable for long-term agricultural use, and when yields start to diminish, farmers will abandon the land and clear more forests. This leads to a loss of biodiversity that is never recovered. In addition, the curing process for tobacco leaves requires heat, which is often generated by burning wood from nearby forests, further contributing to deforestation.

The extensive burning of forests for tobacco growing produces greenhouse gases such as carbon dioxide, sulfur oxides, nitrogen oxides, and carbon monoxide, which contribute to climate change. The loss of forests also intensifies climate change by reducing the planet's ability to absorb these gases. Tobacco cultivation in LMICs is particularly vulnerable to the impacts of climate change, including temperature fluctuations, longer droughts, and more intense rainfall.

The environmental impact of tobacco cultivation is not limited to deforestation and climate change. Tobacco farming also contributes to watershed destruction and increased chemical runoff into waterways, further endangering the health of the environment and local communities.

Burning cigarettes create thousands of chemicals, many known to cause cancer

Cigarette smoke is a major source of air pollution, with studies suggesting that it produces ten times more air pollution than diesel car exhaust. The air pollution emitted by cigarettes is composed of thousands of chemicals, many of which are known to cause cancer. Tobacco smoke is made up of more than 7,000 chemicals, including over 70 known carcinogens. These carcinogens include polycyclic aromatic hydrocarbons (PAHs), N-nitrosamines, aromatic amines, aldehydes, volatile organic hydrocarbons, and metals. Certain types of N-nitrosamines, known as tobacco-specific nitrosamines (TSNAs), are some of the most potent cancer-causing compounds known. They are formed when tobacco is burned and are also found in cigar smoke.

The carcinogens in cigarette smoke can lead to the development of cancer through several mechanisms. One of the primary pathways involves the formation of covalent bonds between the carcinogens and DNA, resulting in the accumulation of permanent somatic mutations in critical genes. These mutations can lead to the development of cancer through clonal outgrowth and the accumulation of additional mutations. Another mechanism involves the direct damage to DNA repair enzymes, which can be overwhelmed by the high levels of DNA damage caused by cigarette smoke. If these repair enzymes cannot function efficiently, the likelihood of developing somatic mutations and cancer increases.

In addition to the carcinogens in cigarette smoke, the burning of tobacco leaves also releases radioactive materials that are present in the tobacco plants due to the fertilizers and soil used during cultivation. Long-term exposure to this radiation can damage the lungs and increase the harm caused by other carcinogens, further elevating the risk of lung cancer.

The pollution caused by cigarettes is not limited to air pollution. Cigarette butts, which are often disposed of on streets, sidewalks, and other public areas, are the most littered item in many countries. These discarded filters contain microplastics and contribute significantly to plastic pollution, ending up in oceans, rivers, soil, and beaches. The tobacco industry is responsible for creating this environmental pollution, and some jurisdictions have implemented legislation to hold them accountable for cleaning up their waste.

Cigarette waste includes packaging, lighters, and matches

Cigarette waste is a significant contributor to environmental pollution. It includes not only the cigarettes themselves but also their packaging, lighters, and matches.

Cigarettes are the most littered item globally, with cigarette butts often disposed of on streets, sidewalks, and other public areas. These butts contain toxic chemicals, heavy metals, and residual nicotine, which leech into the environment, polluting water, air, and land. The filters contain microplastics, contributing to plastic pollution in our oceans, rivers, soil, and beaches.

The packaging associated with cigarettes is also a form of waste. Cigarette boxes and cartons can end up as litter, adding to the overall pollution caused by cigarettes. Additionally, the disposal of lighters and matches used for lighting cigarettes further contributes to the problem. Disposable lighters, in particular, are made of plastic and contribute to plastic waste.

To address this issue, some countries and cities have implemented "extended producer responsibility legislation," holding the tobacco industry accountable for clearing up the pollution it creates. There is also a push for increasing consumer awareness about the environmental impact of cigarette waste and encouraging smokers to dispose of their waste properly or, better yet, quit smoking altogether.

Some smokers opt for matches instead of lighters to reduce their ecological footprint. Matches, especially those made from sustainable materials and non-toxic tips, are considered more eco-friendly and do not taint the tobacco with the taste of butane or other chemicals found in lighters.
