What are the manifestations of tobacco toxicity and what toxins are contained in cigarettes?

1) Mild: the poisoning time is short, and the carboxyhemoglobin in the blood is 10 20. It is manifested as the early symptoms of poisoning, headache, dizziness, palpitations, nausea, vomiting, weakness of limbs, and even short-term fainting.

2) Medium: the poisoning time is slightly longer, the carboxyhemoglobin in the blood accounts for 30 40, and on the basis of mild symptoms, collapse or coma can occur. ** and mucous membranes with a cherry red color characteristic of gas poisoning.

If the rescue is timely, it can wake up quickly, recover completely within a few days, and generally have no sequelae.

3) Severe: found too late, inhaled too much gas, or inhaled high concentrations of carbon monoxide in a short period of time, blood carboxyhemoglobin concentration is often above 50, the patient presents a deep coma, various reflexes disappear, incontinence, cold limbs, blood pressure drops, shortness of breath, and will die soon. In general, the longer the coma, the more serious the prognosis, often with sequelae such as dementia, memory and comprehension loss, and limb paralysis.

Cough. The most common symptom of respiratory illness. It is often mistaken for a respiratory infection.

When cigarettes are burned, more than 4,000 chemicals are released, a considerable number of which are extremely harmful to the human body. Radioactive substances: the main carcinogenic substances of cigarettes.

Mainly radioactive polonium, its radiation energy is high, ionization ability is strong, can easily destroy the genetic factors in living cells, kill cells or convert them into cancer cells. Carbon monoxide: It is not easy to decompose after combining with hemoglobin in the blood, which greatly reduces the ability of the blood to transport oxygen, makes the human body hypoxic, can cause dizziness, nausea, weakness and other symptoms, and can affect cardiovascular function.

Tar: The main substance that cigarettes cause lung diseases, can cause a variety of chronic lung diseases, and can induce lung cancer. Nicotine (nicotine):

It is extremely toxic and can cause the central nervous system to adapt to dependence, which is the main reason why people become addicted to cigarettes. Once dependence occurs, there will be headaches, insomnia, boredom, irritability, lack of concentration and other discomforts during withdrawal, but there is no direct relationship with cancer. Benzopyrene:

Nicotinic (nicotine).

A neurotoxin and highly toxic substance. milligrams per cigarette, the lethal amount of nicotine is milligrams.

The correct answer is: nicotine (nicotine).It's a pity that I answered incorrectly, and I missed today's cake reading again.

Smokers are exposed to a radiation dose of 160,000 microsieverts every year, which comes from the radioactive polonium and radioactive lead in tobacco, so smoking not only increases the risk of lung cancer, but also exposes people to a large amount of radiation every year.

In our daily lives, we receive a radiation dose of 2,000 microsieverts in a year; A CT scan is 7,000 microsieverts; Astronauts, on the other hand, are exposed to 80,000 microsieverts of radiation every year.

The physical manifestations of tobacco poison are as follows:

The pain of lung cancer can be intermittent (confined to the side of the tumor), and the pain may be persistent and increasingly severe, because the lung cancer invades the ribs, intercostal nerves, pleura, etc., which often indicates the progression of lung cancer.
