Which is more harmful, tobacco or alcohol?

Nowadays, many men around us drink and smoke. At a dinner table with friends, wine is an indispensable tool to liven up the atmosphere. Tobacco and alcohol are extremely harmful to the human body. Tobacco contains dozens of substances that are harmful to the human body, especially the lungs. Drinking too much may even lead to sudden death. So, which is more harmful, smoking or drinking?

There is nothing in tobacco that is beneficial to the human body. On the contrary, there are more than 20 substances that are harmful to the body. There are about 70 harmful substances in the smoke produced by smoking.

The most toxic substance in tobacco is nicotine. One cigarette contains 5 to 15 mg of nicotine. The lethal dose of nicotine for humans is 50 mg. That is to say, the nicotine contained in 5 to 10 cigarettes, if injected into the human body at one time, can be fatal. Chronic poisoning from nicotine can cause serious damage to the human nervous system, cardiovascular system, digestive system, etc.

The number one cause of lung cancer is smoking. Some other human cancers, such as esophageal cancer, bladder cancer, pancreatic cancer, colorectal cancer, laryngeal cancer, lip cancer, etc. are also closely related to smoking.

Smokers are exposed to the dangers of radiation every day and every hour. It can cause and aggravate arteriosclerosis and lead to coronary heart disease and stroke.

Smoking can neither relieve fatigue nor increase inspiration. Instead, it reduces the function of the nervous system.

2. The main component of wine is alcohol, whose chemical name is ethanol. When ethanol enters the human body, it can cause many kinds of damage.

When the ethanol concentration in the blood reaches 0.05%, the effects of alcohol begin to emerge, and excitement and euphoria appear; when the ethanol concentration in the blood reaches 0.1%, people will lose self-control. If it reaches 0.2%, a person will be drunk; if it reaches 0.4%, a person may lose consciousness, fall into a coma, or even be in danger of death.

The most important damage that alcohol does to humans is the central nervous system. It causes the nervous system to go from excitement to high inhibition, seriously disrupting the normal function of the nervous system. Excessive drinking can damage the liver. Chronic alcoholism can lead to alcoholic cirrhosis.

In addition, chronic alcoholism can cause damage to the body in many other ways. For example, it can cause multiple neuritis, myocardial disease, cerebral disease, hematopoietic dysfunction, pancreatitis, gastritis and ulcer disease, and can also increase the incidence of hypertension. Others have noted that long-term, heavy drinking can harm reproductive cells and lead to intellectual disability in offspring. The incidence of laryngeal cancer and digestive tract cancer is significantly increased in people who drink alcohol frequently.

To sum up, both smoking and drinking are bad.
