Tobacco smoke contains more than 7000 chemical components.

Tobacco smoke contains more than 7,000 chemical components, of which at least 69 are carcinogens, belonging to Class AB carcinogens.

I. Chemical composition of tobacco smoke

1. Chemicals produced by tobacco combustion

Tobacco burning will produce many chemicals, some of which are harmful. In the flue gas, there are not only common elements such as oxygen and nitrogen, but also more unique compounds such as nitrosamines, polycyclic aromatic hydrocarbons, benzene and other harmful substances.

Acetaldehyde and acetone are the main components of smoke, and some other chemicals such as methyl propionate, butyrate and various alcohols are also included.

2. Chemicals produced in specific environment

In addition to the composition of tobacco itself, some other chemicals will also produce some smoke. For example, when nicotine is extracted by vapor deposition, methyl nicotinate and other harmful gases are produced. Hard cigarette holders and filter tips have a good effect on reducing the content of harmful chemicals, but they cannot be completely removed.

Second, the influence of tobacco smoke.

1. Harmful components

Tobacco smoke contains carcinogens and other harmful components, which will have a significant impact on health. Long-term smoking will not only lead to lung cancer and cardiovascular diseases, but also lead to other diseases.

2. cigarette addiction

Nicotine contained in tobacco is the main factor of cigarette addiction. Smokers often feel relaxed and excited in a short time, but this feeling only lasts for a short time. Smokers must keep smoking new cigarettes to keep their body feeling.

3. Increased risk of chronic diseases

Smoking makes smokers more susceptible to many chronic diseases, including diabetes, heart disease, lung cancer and stroke. According to statistics, smoking is one of the five leading causes of death in the world, and smoking is closely related to lung cancer.

Expand knowledge:

1. Although many countries have implemented smoking ban policies to varying degrees, tobacco smoke still does serious harm to human health.

2. The present science and technology enable us to deeply understand the chemical composition of tobacco, and at the same time provide us with ways to quit nicotine addiction from smoking.

3. Tobacco smoke will also affect non-smokers. Secondhand smoke will not only bring similar but weak health risks, but also greatly increase the number of carcinogens in the environment through air and article pollution.
