What are the harms of smoking to the brain

Everyone knows the dangers of smoking. Not only does smoking cause serious harm to the lungs, but it also causes serious harm to the brain. Therefore, many people who smoke frequently want to fully understand the harms of smoking to the brain. The following content provides a detailed introduction so that you can fully understand the harms to the brain.

Smoking is harmful to health, but most smokers find it difficult to quit smoking. Now smoking among teenagers has become a social problem. A recent research report released by the National Institute of Health in the United States said that the impact of smoking on the brain is long-lasting and the reasons for smoking addiction are similar to the effects of drugs on the brain.

The laboratory analysis of brain tissue by experts from the institute showed that smoking causes changes in brain tissue. Even if they have quit smoking for many years, the levels of two enzymes in the brain's neuronal cells are still higher than those of non-smokers. The same changes occur in the brains of animals that ingest cocaine or heroin, suggesting that similar enzyme changes in smokers' brains are the cause of their addiction.

The Centers for Disease Control and Prevention estimates that there are approximately 45 million adult smokers in the United States, accounting for 21% of the total population, and another 23% of high school students smoke.

A report by the World Health Organization shows that smoking causes at least 25 diseases. The incidence of lung cancer among smokers is 10 times higher than that among non-smokers. One cigarette shortens one's life by approximately 8-11 minutes, and half of long-term smokers will have their life span shortened in middle age. A World Bank survey shows that tobacco-related diseases cost the world $200 billion in medical and health care each year.

A joint survey conducted by China, Britain and the United States shows that China has more than 320 million smokers, making it the world's largest tobacco producer and consumer. 63% of adult men and 4% of adult women smoke, and 2,000 people die from smoking every day. Based on the current situation, 8,000 people will die from smoking every day by 2050.

In our country, the age at which teenagers start smoking has been getting younger and younger in recent years. Parents and teachers should treat this correctly and guide children carefully to let them know the harm of smoking to them, resist smoking from the bottom of their hearts, and consciously stay away from tobacco.

The above content comprehensively introduces the harm of smoking to the brain. For many smokers, they can have a comprehensive understanding and knowledge of this aspect. After a comprehensive understanding and knowledge, in order not to affect the health of the brain, for many smokers, it is best to quit smoking as soon as possible to avoid harm to the brain.
