Cigarette smoke is a complex mixture of chemicals that are produced when tobacco is burned. 

These chemicals can be categorized into several groups, each with its own unique characteristics and potential health effects. 

Understanding the chemical composition of cigarette smoke is vital for assessing its harmful properties and the risks associated with smoking.


Nicotine is one of the most well-known and addictive components of cigarette smoke. 

It is a stimulant that affects the central nervous system, leading to increased heart rate and blood pressure and the release of neurotransmitters like dopamine. 

Nicotine addiction is a significant factor in the persistence of smoking habits and the difficulty of quitting. 

Over time, it can lead to various health problems, including cardiovascular diseases, cancer, and addiction-related challenges.


Tar is a dark, sticky substance that is a byproduct of burning tobacco. 

It contains numerous carcinogens (cancer-causing agents) and is responsible for staining teeth, fingers, and lung tissues in smokers. 

The deposition of tar in the respiratory tract is a primary factor in the development of smoking-related diseases, such as lung cancer and chronic obstructive pulmonary disease (COPD).

Carbon Monoxide

Carbon monoxide (CO) is a colourless, odourless gas present in cigarette smoke. 

It binds to hemoglobin in the blood more readily than oxygen, reducing the oxygen-carrying capacity of the blood. 

As a result, smokers are at risk of reduced oxygen supply to body tissues, leading to fatigue and increased strain on the heart. 

Long-term exposure to carbon monoxide can have severe health consequences, particularly for those with preexisting cardiovascular conditions.

Various Other Toxins

In addition to nicotine, tar, and carbon monoxide, cigarette smoke contains a multitude of other toxic chemicals, including formaldehyde, acetaldehyde, ammonia, and hydrogen cyanide. 

These compounds can irritate the respiratory system, damage DNA, and contribute to the development of cancer and other diseases. 

Some of these toxins also play a role in the characteristic odour of cigarette smoke, making it both noxious and harmful.

Particulate Matter

Particulate matter in cigarette smoke consists of tiny solid particles and liquid droplets suspended in the air. 

These particles vary in size, with some being fine enough to penetrate deep into the lungs. 

Particulate matter in cigarette smoke is a complex mixture that includes ash, soot, and various organic compounds. 

When inhaled, these particles can irritate the respiratory system, trigger inflammation, and contribute to the development of respiratory diseases such as chronic bronchitis and emphysema. 

They can also settle on surfaces, leading to the characteristic staining and odour associated with cigarette smoke.

Gaseous Compounds

Cigarette smoke contains a range of gaseous compounds that are released during the combustion of tobacco. 

These gases contribute to the overall composition of cigarette smoke and have distinct properties and health effects.


Acetaldehyde is a colourless gas with a pungent, fruity odour. It is a known carcinogen and irritant to the respiratory system. 

Prolonged exposure to acetaldehyde can damage DNA and increase the risk of cancer, particularly in the mouth, throat, and respiratory tract. 

It also plays a role in the formation of acetaldehyde-derived DNA adducts, which are associated with tobacco-related cancer.


Formaldehyde is a strong-smelling gas and a well-established carcinogen. 

It can cause irritation of the eyes, nose, and throat when inhaled and has been linked to respiratory problems. 

Formaldehyde exposure from cigarette smoke is concerning, as it can react with other compounds in the smoke to form potentially harmful substances. 

Prolonged exposure to formaldehyde is associated with an increased risk of cancer, particularly in the respiratory tract.


Ammonia is a colourless gas with a strong, pungent odour. 

It is added to some tobacco products to enhance the absorption of nicotine into the bloodstream. 

Ammonia can irritate the respiratory system and contribute to the addictive nature of cigarettes by facilitating the rapid delivery of nicotine to the brain.

Hydrogen Cyanide

Hydrogen cyanide is a toxic gas that interferes with the body’s ability to use oxygen properly. 

It is a product of tobacco combustion and can lead to a decreased oxygen supply to body tissues, potentially resulting in fatigue and stress on the heart. 

Long-term exposure to hydrogen cyanide is associated with an increased risk of cardiovascular diseases and other health problems.

Key Takeaway: 

Cigarette smoke is a complex mixture of chemicals, including nicotine, tar, carbon monoxide, and numerous other toxins, all of which pose various health risks. Understanding this chemical composition is crucial in evaluating the harmful properties of smoking and its impact on health.

Mechanisms of Cigarette Smoke Odour

How Odour Molecules Are Released

The release of odour molecules in cigarette smoke is a complex process that begins with the combustion of tobacco. 

When a cigarette is lit, the high temperatures generated cause the chemical compounds within the tobacco to undergo various reactions, including pyrolysis. 

These reactions break down the tobacco’s organic matter, releasing volatile organic compounds (VOCs) into the air. 

These VOCs are responsible for the distinct smell of cigarette smoke. 

As the smoke is exhaled by the smoker and diffuses into the environment, these volatile molecules disperse and become airborne. 

They can also attach themselves to nearby surfaces, leading to the pervasive odour associated with smoking.

Interaction with Indoor Surfaces

Cigarette smoke odour can remarkably interact with indoor surfaces, including walls, furniture, curtains, and carpets. 

This interaction occurs because the odour molecules in the smoke are often hydrophobic, meaning they have an affinity for surfaces with high surface area and low polarity. 

As smoke particles settle on these surfaces, they can adsorb and absorb into them. 

Over time, this leads to the accumulation of odour molecules, making it challenging to eliminate the smell. 

The porous nature of many indoor materials allows smoke odour to penetrate deeply, making it more persistent and difficult to remove compared to other types of odours.

Persistence and Longevity

The persistence and longevity of cigarette smoke odour are notable characteristics that make it particularly troublesome for indoor environments. 

Unlike some odours that dissipate relatively quickly, cigarette smoke odour can endure for extended periods. 

This persistence is due to the combination of factors such as the chemical composition of the odour molecules, their strong affinity for surfaces, and their ability to become trapped in materials. 

Even after smoking has ceased in space, the residual odour can linger, affecting the indoor air quality and the comfort of individuals in the area. 

Effective removal of cigarette smoke odour often requires a combination of thorough cleaning, ventilation, and the use of odour-neutralizing products to break down and remove these stubborn odour molecules.

Key Takeaway: 

Understanding cigarette smoke odour involves recognizing that it is released through the combustion of tobacco, attaches to indoor surfaces due to its chemical properties, and exhibits remarkable persistence, making it challenging to eliminate without targeted strategies such as cleaning, ventilation, and odour-neutralization.

Factors Influencing Odour Intensity
