Nicotine Pollution: Harming Our Air And Health

Tobacco is a well-known health hazard, but it also has a significant environmental impact. From the high carbon footprint of its production and consumption to the toxic waste that ends up in our oceans, rivers, and soil, tobacco products contribute to air, water, and land pollution. Cigarette butts, in particular, are a major source of pollution, as they contain nicotine, pesticides, heavy metals, and other toxic chemicals that leech into the environment. With cigarettes being the most littered item globally, the pollution they cause is a growing concern, impacting not only the health of individuals but also the planet.

Nicotine and air pollution indoors

Tobacco use is a significant health and environmental issue. Cigarette butts are the most littered item globally, and their waste pollutes water, air, and land with toxic chemicals, heavy metals, and residual nicotine.

Tobacco smoke is a critical factor in indoor air pollution. Its components, including nicotine, can linger in indoor spaces for extended periods, posing health risks to occupants. A study found that a non-smoker living with a smoker is exposed to similar levels of harmful particles as a non-smoker residing in a highly polluted city. The smoke emitted from cigarettes contains particles from additives and paper, such as tar, nicotine, and heavy metals.

Secondhand Smoke (SHS) releases approximately 10.5–34.4 mg of particulate matter and 1.9–5.3 mg of nicotine per cigarette into the air. Worldwide, cigarette smoking releases about 22 million kilograms of nicotine into the atmosphere annually. SHS has been linked to various health issues, including lower respiratory infections in young children, ischaemic heart disease in adults, and asthma in both adults and children.

Indoor vaping conventions, where e-cigarette use is permitted, have also been found to significantly impair indoor air quality. High concentrations of particulate matter, volatile organic compounds (TVOCs), carbon dioxide (CO2), nitrogen dioxide (NO2), and airborne nicotine are detected at these events. The surfaces in the venue may become impregnated with deposited aerosol, leading to potential third-hand exposure and nicotine exposure via direct skin contact.

To reduce the health risks associated with indoor nicotine pollution, it is crucial to promote smoking cessation and provide support for those seeking to quit tobacco use. Additionally, proper disposal of cigarette and e-cigarette waste is essential to minimise their environmental impact.

Nicotine in cigarettes and air pollution

Tobacco use is a significant health issue, and it is also an environmental issue. Cigarettes are the most littered item in many countries, and cigarette butts cause pollution by being carried as runoff to drains and from there to rivers, beaches, and oceans. Preliminary studies show that organic compounds such as nicotine, pesticide residues, and metals seep from cigarette butts into aquatic ecosystems, becoming toxic to fish and microorganisms. This has been demonstrated in laboratory studies, where toxins from a single cigarette butt soaked in water for 24 hours were enough to kill 50% of the saltwater and freshwater fish exposed to it for 96 hours.

Tobacco smoke is a real factor in indoor air pollution, and its components can remain in rooms for extended periods. Tobacco smoke is an aerosol, a mixture of 90% gas and 10% particles. According to the Academy of Medicine, cigarette smoke is one of the biggest indoor pollutants due to the harmful particles it contains. These particles, including tar, nicotine, and heavy metals, are released into the air when a cigarette is smoked. Secondhand smoke (SHS) releases 1.9–5.3 mg of nicotine per cigarette into the air, and worldwide, cigarette smoking releases about 22 million kilograms of nicotine into the atmosphere annually.

The harmful effects of tobacco smoke exposure are well-documented, particularly in relation to cardiovascular diseases. Epidemiological studies have confirmed that air pollution, including that caused by cigarette smoking, is linked to an increased incidence of myocardial infarction and fatal coronary artery disease in both males and females. Passive smoking, or exposure to ambient tobacco smoke, is associated with a 30% increased risk of coronary artery disease, while active smoking is associated with an 80% increased risk.

The impact of tobacco extends beyond just the smoke it produces. The tobacco industry's carbon footprint from production, processing, and transportation is significant, contributing to global warming. Additionally, the littering of cigarette butts and e-cigarette waste contributes to plastic pollution and the release of toxic chemicals and heavy metals into the environment. E-cigarette waste, in particular, contains metal, circuitry, disposable plastic cartridges, batteries, and toxic chemicals in e-liquids, making it a serious environmental threat.

To address these issues, some countries and cities have implemented "extended producer responsibility legislation," holding the tobacco industry accountable for clearing up the pollution it creates. This includes encouraging tobacco farmers to switch to sustainable crops, implementing tobacco taxes, and offering support services to help people quit tobacco use.

Nicotine in e-cigarettes and air pollution

While the harmful health effects of tobacco smoking are well-known, the impact of tobacco product use on the environment is less recognized. Tobacco use is an environmental issue, as cigarettes are the most littered item in many countries. Cigarette butts and electronic cigarette components can leach contaminants into the soil, water, and air.

Tobacco smoke is a real factor in indoor air pollution, and its components can remain in the rooms for extended periods. A study has shown that a non-smoker living with a smoker breathes in as many harmful small particles at home as a non-smoker living in a highly polluted city. Tobacco smoke is an aerosol, a mixture of 90% gas and 10% particles. According to the Academy of Medicine, cigarette smoke is one of the biggest indoor pollutants due to its harmful particles, including tar, nicotine, and heavy metals.

E-cigarettes have gained popularity, and their use has become a source of concern for indoor air pollution. Studies have confirmed that e-cigarette aerosol is a significant source of indoor air pollution, impairing indoor air quality. E-cigarette conventions, where indoor use is allowed, have been found to have high levels of particulate matter, volatile organic compounds, carbon dioxide, nitrogen dioxide, and airborne nicotine, significantly impacting indoor air quality.

E-cigarettes do not burn tobacco, so they produce less secondhand aerosol and have lower levels of nicotine pollution than conventional cigarettes. However, bystanders around people using e-cigarettes still absorb nicotine and other pollutants. The nicotine levels in non-smoking bystanders exposed to e-cigarette vapors were found to be similar to those exposed to secondhand cigarette smoke.

The waste generated by e-cigarettes is also an environmental concern. Unlike cigarette butts, e-cigarette waste is not biodegradable and contains metal, circuitry, plastic cartridges, batteries, and toxic chemicals in the e-liquids. E-cigarette cartridges discarded on streets can break down into microplastics and chemicals, polluting waterways and wildlife.

Nicotine and its environmental impact

Nicotine is just one of the thousands of chemicals found in tobacco products, and it has a significant impact on the environment. Tobacco use is not only a health issue, it's also an environmental issue. From growing tobacco plants to disposing of butts and packaging, the entire life cycle of a cigarette negatively affects the environment.

Tobacco cultivation is promoted to farmers as a profitable venture, but it is labour and resource-intensive, and it is harmful to both the environment and farmers' health. Tobacco production endangers food security, as it diverts agricultural land that could otherwise be used to grow food. The tobacco curing process, in particular, is highly energy-intensive, contributing to greenhouse gas emissions and deforestation. It is estimated that close to 50 million trees are cut down every year for curing tobacco leaves.

Tobacco products are the most littered item on the planet, containing over 7,000 toxic chemicals, including nicotine, that leech into the environment when discarded. Cigarette butts, in particular, cause pollution by being carried as runoff to drains and from there to rivers, beaches, and oceans. Preliminary studies show that organic compounds, including nicotine, seep from cigarette butts into aquatic ecosystems, becoming acutely toxic to fish and microorganisms. In addition, tobacco smoke is a significant factor in indoor air pollution, as its components can remain in rooms for extended periods.

E-cigarette waste is also a serious environmental threat. Unlike cigarette butts, e-cigarette waste is non-biodegradable and contains metal, circuitry, disposable plastic cartridges, batteries, and toxic chemicals in e-liquids. These chemicals can flow into storm drains, polluting waterways and wildlife.

The environmental impact of the tobacco industry is complex, and the lack of mandatory guidelines for transparent reporting of environmental data makes it difficult to fully understand the extent of the problem. However, the World Health Organization (WHO) has raised alarms about the industry's environmental impact, calling for steps to hold the industry accountable for the destruction it is causing.

Nicotine and health

Nicotine is a highly addictive chemical that can be found in cigarettes, e-cigarettes, cigars, and other tobacco products. It is a dangerous substance that can cause an increase in blood pressure, heart rate, and blood flow to the heart. Nicotine may also contribute to the hardening of the arterial walls, which can lead to a heart attack. The effects of nicotine exposure can last for up to eight hours, depending on the frequency of use.

Nicotine poses several health hazards, including an increased risk of cardiovascular, respiratory, and gastrointestinal disorders. It can also decrease immune response and negatively impact reproductive health. Nicotine affects cell proliferation, oxidative stress, apoptosis, and DNA mutation, which can lead to cancer. Acute nicotine exposure can be toxic, and poisoning can occur through swallowing, breathing, or absorbing vaping liquid through the skin or eyes.

The use of nicotine during adolescence can harm brain development, particularly in the areas that control attention, learning, mood, and impulse control. Youth are especially vulnerable to nicotine addiction, and signs of addiction can appear quickly, even before regular or daily use. Nicotine addiction can also harm mental health and be a source of stress, with withdrawal symptoms including cravings, inability to stop using, and developing a tolerance.

Nicotine addiction is not limited to youth, and thousands of people struggle with it each year. Quitting nicotine is challenging, and the body and brain must adjust during the withdrawal process. However, quitting is the best thing one can do for their health, as it frees individuals from the chains of addiction and improves overall well-being.

In addition to the direct health consequences, nicotine also contributes to environmental pollution. Cigarette butts, for example, are the most littered item globally, and they contain toxic chemicals, heavy metals, and residual nicotine, which can pollute water, air, and land. The tobacco industry's carbon footprint from production, processing, and transportation further exacerbates the problem, contributing to global warming.
