Tobacco contains nicotine, which is an alkaloid and has neurotoxicity, especially fatal to insects, but it can stimulate human nerve excitement, and the tolerance will increase after long-term use, but it also produces dependence. According to research, all nicotine contained in three cigarettes or half a cigar can kill people, but the nicotine inhaled by smokers is only a small part of it. Tobacco can also be used to make pesticides and extract nicotine, malic acid and citric acid.
Modern research has confirmed that tobacco still contains some carcinogens, which has attracted more and more attention. Smoking in public places has been banned in many places to protect public health. The laws of many countries stipulate that the words "Smoking is harmful to health" must be printed on cigarette cases. The laws of the People's Republic of China stipulate that cigarette advertisements are not allowed in any media or public places. Thailand stipulates that pictures of the harm caused by heavy smoking must be printed on cigarette cases, such as the damaged teeth of smokers and the blackened lungs of smokers, so as to alert smokers and achieve the effect of quitting smoking. Bhutan banned all tobacco imports and became the first smoke-free country.
America
Tobacco was first used by American Indians. Since it was adopted by Europeans, the demand for tobacco has increased dramatically. However, the climate in Europe is not suitable for tobacco growth, so the United States has become the largest tobacco producer and exporter. At that time, the saying goes: "America started with tobacco", and tobacco cultivation prompted the United States to use a large number of black slaves, which became an important pillar industry for the formation of slavery in the United States at that time. Until 1883, tobacco taxes accounted for more than one-third of the US government's fiscal revenue.
China
The history of tobacco in China can be traced back to the Ming Dynasty. In 1575, tobacco was introduced to Taiwan Province and Fujian from Luzon. In 1579, Matteo Ricci brought snuff to Guangdong, and the smoking population in China rose greatly. In 1637, in order to ban smoking, Chongzhen ordered beheading to punish private sellers. However, Hong Chengchou, the minister of the Ministry of War who fought hard in Liaodong and the late Jin Dynasty, said that "foot soldiers in Liaodong are addicted to this life", which led to obstacles in the process of smoking ban.
The legend of tobacco in China
During the Wanli period of the Ming Dynasty, a Li Juren from Hangzhou went to Beijing to take the exam. When he left, his father prepared a letter asking him to visit an old friend in Suzhou to help with some travelling expenses. This old friend, surnamed Zhang, was an official with the DPRK and was very friendly. It happened that the two families gave birth to a man and a woman in the same year, so they decided to cut their robes. Later, the Li family suffered from natural disasters and went poor. They were afraid that the Zhang family would regret their relatives and never mentioned this to their son.
Zhang's father was very happy when he saw that Li Juren was handsome and knew how to receive a gift. He immediately went in and told his wife. The lady secretly told her daughter. The whole family was warmly entertained, and the future uncle was drunk as a fiddler and helped into the study to sleep.
In the middle of the night, Li Juren felt groggy and couldn't bear to drink. She shouted, "Tea, tea." At this time, Miss Zhang in the embroidery room next door was still not asleep. Hearing the shouts, I got the nerve to pour a cup of strong tea and send it. Li Juren saw a beautiful woman approaching the bed in a daze, just like Chang 'e going to the moon palace and Guanyin sending nectar, and her heart was drunk. When I reached for the tea, I intentionally grabbed Miss Zhang's wrist and held it over. Miss Zhang blushed and her heart jumped. Li Juren became more and more fascinated, and the trend gently pulled Zhang girl in her arms. Miss Zhang thought that he knew he was his fiancee and would always be his family in the future, so it was a good thing to give up.
The next day, Li Juren woke up, thinking of last night's scene, feeling uneasy, getting up in a hurry and saying goodbye to Zhang Fu. Zhang Fu couldn't stay, so he gave him travelling expenses to send him on his way.
after three exams, I won the top prize. Return to your hometown on orders. Father Li said to the champion Lang, "to be no.1, you can go home on leave and get married." The champion said, "How can you say you are married before your child is engaged?" Li's father was surprised. "Li and Zhang were married when they were young. Didn't Zhang mention it in Suzhou a few days ago?" When Li Zhuangyuan heard this, he poured cold water from head to toe, complaining in his heart: This girl is frivolous, and I just pulled it lightly and followed me. If I marry such a woman, it will not humiliate my family. When I thought of this, I said, "The child is still young, and we will talk about it after two years of marriage." Father Li said, "My parents are the masters of the marriage. I have chosen the auspicious day of the ecliptic and will go to Suzhou in a sedan chair tomorrow."
Li Zhuangyuan broke his teeth and swallowed, but he couldn't speak. I sent a letter to Suzhou by a thoughtful messenger overnight, and Miss Zhang received it personally. Miss Zhang already knew that Li Jialang had won the top prize, so she chose an auspicious day and came to marry her. I am in high spirits. When I opened the letter, I was dumbfounded and burst into tears. The letter said, "To be the top lady, you have to die first." I thought that I was short of ideas at the beginning, and the champion Lang mistakenly thought it was a thin willow. Therefore, don't regret it or blame it. I wrote a suicide note and hanged myself.
Zhang's parents cried their eyes out. The sedan chair arrived at the door and married the body in accordance with Miss Zhang's suicide note. When the champion saw that Miss Zhang was a loyal woman, she regretted it. She cried bitterly and vowed, "I will never marry again in this life."
Li Zhuangyuan missed his wife, and he was often unhappy. One day, when he went to the grave, he saw a lot of broadleaf grass growing on it. He picked a piece of it and chewed it carefully. It tasted bitter and fragrant, so he put it away and put it on his desk. Once, the champion was reading under the lamp, and a snuff exploded on a dry leaf, which burst into smoke and smelled fragrant. From then on, when he missed his wife, he burned the leaves dry and sucked. That's when smoking started.
