What is the chemical composition of cigarettes?

Tobacco is mainly composed of carbohydrates (40%-50%), carboxylic acids, pigments, terpenes, alkanes and lipids. At the same time, there are some nutrients (such as nitrate) and some pollutants (such as pesticides and important gold modification elements) necessary for growth.

Because of different brands, producing areas and production batches, the content of cigarettes will be different.

Common toxic substances in cigarettes:

Nicotine: the main effective component in cigarettes, which can stimulate the human body and make people addicted.

2. Acetone: It will affect the skin, mouth, kidney and liver, and cause nerve damage and birth defects.

3. Aluminum: can cause contact dermatitis; This is also related to Alzheimer's disease.

4. Ammonia/ammonia: damage to alveoli.

5. Arsenic: Visceral poisoning, and can cause cancer.

6. Benzene: toxic; The International Agency for Research on Cancer lists it as the first class carcinogen: irritability, lethargy, dizziness, heartbeat, headache, tremor, confusion, vomiting, unconsciousness and death.

7. Butane: If carbon monoxide/carbon dioxide makes the air supply insufficient, it will produce carbon (carbon black) and carbon monoxide to isolate the heart and lungs from oxygen contact and breathing, leading to closed death.

8. Cadmium: It affects respiratory tract, kidney, liver, rickets and other diseases.

9. Cesium: Caffeine that causes irritability: It can stimulate the brain nerve center of the human body and make the human body insomnia.

10. Carbon monoxide: headache, respiratory problems, dizziness and unconsciousness. Carbon dioxide: a toxic gas, such as gas inhaled into the body, can make people have difficulty breathing and suffer from lung cancer and hepatitis.

1 1. Rosin: copper: an enzyme that affects hematopoiesis.

12. Cyanide/hydrogen cyanide (cyanide): can cause coma, cardiac arrest and death. Weak, sleepy, anxious, excited. Dizziness, nausea, vomiting, sweating, weakness of fingers and toes, difficulty in walking, impaired vision and hearing, decreased thyroid function and skin pain.

In a word: smoking is harmful to health. For the sake of your family and your health, please quit smoking in time.

Extended data:

According to scientists, tobacco contains hundreds of complex chemical components, most of which are harmful to human body. Among them, 40 kinds of tar, nicotine, phenols, alcohols, acids and aldehydes are toxic and carcinogenic.

After the cigarette is lit, the smoke produced contains all the chemical components in tobacco, and at the same time, it also adds some harmful substances to tobacco itself, such as carbon monoxide and cigarette tar. This is because in the process of making cigarettes, in addition to the tobacco itself, some substances such as cocoa, licorice, sugar, glycerol and ethylene glycol are added to the raw materials.

Although these additives are harmless in themselves, they have changed during combustion. For example, when the back of a mouse is coated with smoke oil produced by cocoa burning, skin tumors will grow. Glycyrrhizic acid in licorice. After combustion, it can be combined with other components to generate carcinogenic polycyclic aromatic hydrocarbons.

When sugar is burned with tobacco, the tar content increases, and the products of sugar combustion are important carcinogens in tobacco. After burning, substances such as glycerol and ethylene glycol may not only make smokers suffer from bladder cancer, but also produce acrolein, which inhibits the discharge of tracheal and ciliary secretions from the lungs, thus increasing the chances of suffering from tracheitis and emphysema and aggravating the conditions of people suffering from these two diseases.
