Who invented cigarettes?

The Spanish explorers Aztecs and Mayans discovered cigarettes.

A cigarette is a tobacco product. The production method is to dry tobacco and shred it, and then grow it into a barrel-shaped strip with a diameter of 120mm in a paper roll. When smoking, one end is lit, and then the smoke is breathed through the mouth at the other end. Cigars are smoked by rolling tobacco into cylindrical strips. The main difference between cigarettes and cigars is that cigarettes are smaller and tobacco is finely chopped. Cigarettes were first popular in Turkey, and locals like to roll up tobacco with newspapers and smoke it. During the Crimean War, British soldiers learned the method of smoking from the soldiers of the Ottoman Empire at that time, and then spread it to different places. 1843 On June 25th, France began to manufacture the first batch of cigarettes for commercial sale in history. Later, cigarettes became popular everywhere.

Hazards of smoking:

1. Lung diseases: 38 kinds of toxic chemicals are released when cigarettes are burned, among which tar, carbon monoxide, nicotine, dioxins and irritating smoke are harmful components. Tar is harmful to the mouth, throat, trachea and lungs. Tar in tobacco smoke is deposited on lung villi, which destroys the function of villi, increases phlegm and causes chronic bronchial diseases, such as tracheitis, emphysema, pulmonary heart disease and lung cancer. According to statistics, the proportion of smokers suffering from lung disease after 60 years old is 74%, while the proportion of non-smokers suffering from lung disease after 60 years old is only 4%, which is a shocking figure.

Second, cardiovascular diseases: carbon monoxide in cigarettes reduces the oxygen content in the blood, causing hypertension and other related diseases. Smoking will contract coronary artery, reduce or block supply, and lead to myocardial infarction. Smoking can increase adrenaline, make the heart beat faster, increase the heart load, affect blood circulation, and lead to more than 20 diseases such as cardiovascular and cerebrovascular diseases, diabetes, sudden death syndrome, decreased respiratory function and stroke.

Third, smoking causes cancer: The study found that smoking is the fastest and richest way to produce free radicals. Each cigarette will produce at least 654.38+10,000 free radicals, which will lead to cancer and many chronic diseases. A 50-year study of 35,000 smokers in Tidcliffe Hospital, Oxford, UK, concluded that lung cancer, gastric cancer, pancreatic cancer, bladder cancer, liver cancer, oral cancer and nasal sinus cancer were "significantly related" to smoking. People who smoke are prone to catch a cold, because the activity of human lymphocytes decreases, leading to cancer. In view of the three major factors leading to smoking and cancer, the sooner you quit smoking, the better.

Fourth, smoking can also lead to osteoporosis and early menopause. Smoking can make men lose their sexual and reproductive functions. Smoking in pregnant women will lead to premature delivery and underweight of the fetus, and the probability of miscarriage will increase. Smoking makes teeth yellow, which makes bad breath easy. Smoking harms people, and the harm of passive smokers is five times that of smokers.

Fifth, the harm of smoking to intelligence. Smoking will affect people's attention. Some people think that smoking can refresh the mind, eliminate fatigue and inspire, which is totally unreasonable. Experiments show that smoking seriously affects people's intelligence and memory, thus reducing the efficiency of work and study.
