What are the dangers of smoking?

1. Smoking can cause heart disease

Normally, when people smoke cigarettes, they absorb a large amount of carbon monoxide, which reduces the blood's ability to absorb oxygen. In addition, the nicotine in cigarettes will speed up people's heart rate and increase blood pressure, putting greater pressure on the heart. Over time, it will cause myocardial hypoxia and coronary artery infarction, or angina pectoris, which is extremely harmful to physical health.

2. Smoking harms the brain

Smoking also has obvious harm to the human brain. After people smoke, their brain circulation will slow down, and their brain blood vessels will bleed or become blocked, which will lead to a decline or decline in intelligence. In addition, people who smoke frequently will cause platelets in their blood to coagulate and their brain blood vessels to spasm, which may lead to a stroke in severe cases.

3. Harm of smoking to the oral cavity

Smoking not only harms people's hearts and brains, but also has obvious harm to human oral cavity. People who smoke frequently are more likely to suffer from laryngeal cancer and oral cancer because the tar and smoke in cigarettes can inflame people's salivary glands and damage taste buds. In severe cases, people can lose their ability to smell.
