What are the consequences of people who often take drugs? Thank you, everyone. From the biomedical point of view, the consequences of drug abuse are negative, and the harm to the human body greatly exceeds the possible benefits. Due to space reasons, this paper mainly introduces the consequences of three main drugs (heroin, marijuana and cocaine) on human body. Heroin Heroin belongs to opiates. This * * * is extracted from poppy (Latin Papaver somniferum). This poppy grows in the Middle East, India, Pakistan, Afghanistan, Southeast Asia and China. Mexico, Central and South America, France, Eastern Europe, Central Asia, South Korea, Australia and parts of Africa. Morphine is a natural derivative of poppy. At the beginning of the 20th century, morphine was a widely used analgesic. The invention of hypodermic syringe and the use of morphine in the armies of various countries made thousands of soldiers become "addicts". Therefore, morphine addiction is also called "military disease". Heroin was synthesized from morphine in 1898 and began to be used to quit opium addiction or morphine addiction. However, it was later found that it was twice as addictive as morphine. At the 19 12 National Opium Conference held in The Hague, the participating countries agreed to control the trafficking of opium, morphine and heroin in order to reduce the rising addiction rate. However, no matter how much efforts western countries have made, heroin is still the most widely used drug today, and it has done more harm to western society than any social problem. The direct self-perception effect after heroin abuse can be divided into two stages:' motivation' and' anesthesia * * *'. Users immediately feel an' impulse' after taking it, which is * * * all over the body, similar to the ecstasy when * * *. This * * * is often accompanied by a sharp increase in energy and an increase in mental movement. The ensuing' * * *' or * * * lasts longer, but it feels hard to describe. The perceptual state at this time is similar to a dream, which is very pleasant and has a strong sense of comfort. Then I will take a nap with my head down, and there will be an internal attention phenomenon, accompanied by a tendency to escape from the outside world. At this time, it is called emotional analgesia, and the individual gets rid of all pain, anxiety, worry and pursuit. An addict described heroin as "an eternal death-a life without pain". The short-term physiological effects of taking heroin and other opioids are: blocking the digestion and passage of food in the gastrointestinal tract; * * * vomiting center, nausea and vomiting; Dilating blood vessels, causing congestion and redness of the panel; Pupil contraction; * * * Brain stem and respiratory center cause respiratory decline, and the dose is probably large, and the more serious the respiratory decline, the more severe the dose, the respiratory failure and death; * * * The cough center of the brain inhibits cough reflex; Change the state of consciousness, lose pain (its analgesic effect is not to block nerve impulses). After repeated use of heroin, drug resistance occurs, that is, each dose must be increased to produce the same effect; Physical and psychological dependence, if the drug is stopped, even the normal metabolic function can not be carried out normally, there will be a serious' withdrawal syndrome', sometimes leading to death. Withdrawal syndrome includes: anxiety, irritability, irritability, watery eyes, body pain, insomnia, alternating sweating and chills, dilated pupils, goose bumps, sudden burning sensation, vomiting, and choking throat. Taking heroin for a long time can also lead to constipation, loss of appetite, impotence or infertility; Long-term injection of the drug will lead to vascular collapse and venous scarring; People who take heroin for a long time are intoxicated, seldom eat and don't care about their health, which leads to malnutrition, anemia and high infection rate. Heroin is extremely dangerous, because it is addictive and causes respiratory failure in large doses and dies; Combined with alcohol or barbiturates can also lead to death; Because the obtained heroin is often diluted or adulterated, the quantity and quality of drugs have changed greatly, which is extremely harmful to users until they die; Because the injection needle or needle tube is unclean, it is easy to suffer from abscess, septicemia, tetanus and infection with pathogenic bacteria and viruses, thus suffering from hepatitis and AIDS. Cannabis sativa (Latin name for Cannabis sativa) is a shrub that can grow in most temperate and tropical regions of the world, and its flowers and leaves can become * * * products after drying. Among them, tetrahydrocannabinol is the main component that plays a significant role in the spirit, and the more components it has in cannabis drugs, the stronger its effect will be. Today, most of the world's cannabis is grown in Mexico and Colombia. After inhaling the smoke of marijuana cigarettes for a few minutes, you will feel comfortable, comfortable and quiet, similar to drunkenness; Will feel in a daze, groggy, and have the feeling of being in a dream; Be friendly to yourself and others, and like to be with others; Enhance the perception of the environment, visual and auditory feelings are more acute; The relationship between people feels more meaningful; I feel that I have a particularly sensitive epiphany ability. Higher doses of marijuana can cause people to be lazy, short-term memory confusion, emotional ups and downs, and may also cause dizziness, nausea, vomiting and other symptoms. High-dose marijuana can distort people's vision and hearing, feel that they are separated from their bodies and feel that everything is illusory. The direct effects of marijuana on human body are: accelerated heart rhythm, enhanced epidermal blood circulation, red eyes due to blood vessel congestion, thirsty throat, blood pressure fluctuation, respiratory and body temperature changes. Long-term inhalation of tobacco smoke has the same effect on the lungs: inflammation, emphysema or lung cancer; It may reduce male fertility and affect female postpartum prolactin, and tetrahydrocannabinol will appear in breast milk; Will affect the heart rhythm and heart function; Weaken immunity; It produces tolerance and dependence, and once it is removed, the following symptoms will appear: loss of appetite, insomnia, anxiety, irritability, hyperactivity, hyperhidrosis, sudden weight loss, and elevated intraocular pressure. Case 25: Steven is a handsome tall boy, the best student and top athlete. Some of his friends gave him a taste of marijuana. He tasted the sweetness of smoking marijuana and smoked it every day after school. Soon, his academic performance declined, and he was unable to concentrate and had difficulty remembering. He lost his dexterity as an athlete and was expelled from the team. He said, "I feel something is wrong all day. Everything I used to like has become a burden. " His parents took him to see a doctor. The doctor found that the letters' b' and' d' in his handwriting were often reversed, which showed that his learning ability was damaged. Brain waves are also abnormal. Eight weeks after Stephen quit marijuana, his EEG improved obviously, his academic performance improved, and his mood, memory, sense of humor and speaking ability improved. Two months later, his EEG returned to normal. Because tetrahydrocannabinol has affinity to adipose tissue, it accumulates in adipose tissue, and the brain is an organ containing a lot of fat. It is reasonable to worry that smoking marijuana will affect thinking, mood, dedication and motivation. This can illustrate Stephen's example. However, students with the best grades may also use marijuana and still maintain their best grades. Cocaine Cocaine is extracted from the leaves of a South American plant called coca bush. The production and export of cocaine are mainly in some countries in South America. In these countries, chewing coca leaves is a long-term habit of local people, and many people make a living by planting coca trees. Cocaine is usually inhaled into the nostrils, where it is adsorbed on the nasal mucosa, or injected intravenously with a syringe. Cocaine can cause vasoconstriction and can be used as a local anesthetic in surgery. 1884, Freud described his feelings about cocaine in his paper entitled "About the Coca Tree": "The spiritual function of cocaine includes excitement and euphoria, which is no different from the normal euphoria of healthy people. Users feel that their self-control ability has improved and their working ability has improved. He just feels normal and happy, and it's hard to believe that he is controlled by drugs. He can tirelessly engage in long-term, high-intensity mental or physical work. The requirement of eating and sleeping, which is inevitable at some time, seems to have completely disappeared at this time. " Cocaine * * * nervous system, produce euphoria, self-confidence, competent for all heavy work and excitement, but this state only lasts for about 30 minutes, and then turns into a state of inhibition. The decline of drug power drives drug addicts to use it again. In this way, they use it every ten minutes to keep their internet addiction from falling. Low-dose cocaine can excite the higher brain centers, resulting in euphoria, irritability and excitement. When the dose increases, the brain center in the lower position is also affected by * * *, which leads to the acceleration of breathing and heart rhythm, vomiting, tremor, spasm and convulsion. When you enter the state of inhibition, the above symptoms will stop. If the dose is large enough, deep suppression will lead to respiratory failure and death. There are two kinds of cocaine poisoning: one is that if users are particularly sensitive to this drug, even if they use a small dose, they will collapse: pale face, dizziness, vomiting, weak pulse and unconsciousness; The other is that the dose is too large, which leads to delirium, spasm, mania, and finally respiratory failure and death. Cocaine also excites the brain center that controls body temperature and causes vasoconstriction. The combination of these two effects will lead to an increase in body temperature, but due to the contraction of blood vessels, it is impossible to sweat, which will lead to death. People who use cocaine in large quantities may lose weight, suffer from insomnia and anxiety, and some tissues of nasal mucosa will be necrotic and ulcerated due to vasoconstriction. Continuous inhalation of this drug will cause perforation or even collapse of the nasal septum. Cocaine is highly addictive. People who use cocaine in large quantities for a long time will have hallucinations and low spirits once they don't use it. Using cocaine can easily lead to using heroin. Bai Zhongyan's understanding of the effect of using * * * products is quite different, because its effect is complex, in which biological, psychological and social factors are intertwined, and it is difficult to distinguish jobs. For example, there is no objection to the role and control of the highly toxic drug potassium cyanide. * * * Products have different effects on different people. Some people drink a lot of wine but it doesn't work, and the same amount of alcohol will make others sick or out of control. * * * The emotional reaction of products to users also varies from person to person. * * * The variability of product effects raises a question for sociologists: What should be regarded as deviant is their use itself, or the consequences of use (such as loss of self-awareness and out-of-control behavior). )? The factors that affect the product effect are: ① The human body is a very complicated system. In particular, the receptors on individual cell membranes are very different, which determines the effect of * * * products on different individuals to a considerable extent. ② Lag reaction. If there is a long interval between medication and drug action, people may not think that a certain behavior is the action of drugs. ③ Adaptation effect. The body has adapted to the medicine it takes, thus weakening or changing the effect of the medicine. For example, in the process of taking addictive drugs, users will develop drug resistance. At this time, if you take a certain dose of * * * regularly, your body will function normally, and increasing or decreasing the dose will have obvious effect, but it will not have obvious effect without increasing or decreasing the dose. ④ Psychological comfort effect. The human body has the ability to produce effects without "cause". If you give a person who smokes marijuana regularly a drug and tell him that he is smoking marijuana, it will have the effect of marijuana. ⑤ Drug interaction. Taking alcohol will greatly enhance the medicinal properties of barbiturates, leading to the death of users. Many people died of a mixture of whisky and barbital. A small amount of amphetamine has an exciting effect, and a small amount of heroin or methadone will double the effect of heroin. [Douglas et al] Drug abuse has a serious harmful effect on oneself, family, community and society. 1. Harm to drug addicts themselves: First of all, it is very harmful to the health of drug addicts. According to the statistics of the British Ministry of Health, the death rate of drug addicts is 28 times that of others, and the average life expectancy of drug addicts is 40-50 years, while the average life expectancy of British people is 74.2 years. In Japan, people find that the hearing and vision of drug addicts are declining, and there are more and more serious traffic accidents. On March 25th, 1990, China Daily reported that 43 people died of drug overdose in Yunnan province. In Zhuhai 1990- 199 1 year, five people died of drug overdose. * * * Needles and syringes are easily infected with hepatitis B virus or HIV. Secondly, their mental health has also been greatly damaged. Some people seem to want to use drugs to treat or alleviate their psychological trauma, and as a result, the use of drugs makes their psychological trauma "worse." Third, their social well-being has also been completely destroyed. The drug addict can't find a job, which makes him alienated and marginalized. People with a lot of money will lose everything if they take drugs. And they have lost a person's most precious thing: freedom and autonomy. They lost their freedom, everything was driven by drug addiction, they could not be their own masters, and drug addiction dominated everything. Case 26: Youth A in Baoan County, Shenzhen. His father in Hong Kong rented a taxi for him and he made a lot of money. Soon he became addicted to drugs. Drug addiction is getting bigger and bigger. It cost hundreds of thousands in less than two years. His body is getting weaker and weaker, his face is yellow and emaciated, and his eyes are dull. But when he was addicted to drugs, he still injected drugs. His girlfriend left him. In order to save her son's life, the mother asked her relatives to chain her son to a post, and finally she sent him to a drug rehabilitation center. Case 27: Zhuang, a waitress in Kunming Camellia Hotel, is female, 17 years old, young and beautiful. She can speak fluent English, is serious and responsible, and treats guests warmly and thoughtfully. She won the praise of Chinese and foreign guests. She was rated as an advanced worker twice and was addicted to heroin under the temptation of her boyfriend. Not only did she spend all her savings on drugs, but she also borrowed 5000 yuan from her parents to buy drugs. In order to get the money, she altered the phone bill receipt of 1 1, overcharged cash, then entered the safe, opened the safe, stole 95,000 yuan deposited by passengers, and degenerated into a corrupt thief. 2. Harm to families and communities: Drug addicts have brought serious economic and psychological harm to families, even to bankruptcy or disintegration. Drug addicts often turn themselves from family providers into family parasites. They may become "millionaires". The family depends on him and their lives are stable. The children are well educated. But once they are addicted to drugs, they can lose everything in a short time, and everything at home can be stolen and sold by him for drugs. This is why many families take the initiative to send drug addicts to drug rehabilitation centers. For example, Hongmou owed nearly 10,000 yuan for drug abuse. When he learned that his father was going to do business and got a loan of 5,000 yuan, he hacked his father to death with an axe and snatched 5,000 yuan in cash. Li took drugs, sold four children, and his wife committed suicide. The bankruptcy of drug addicts' families has increased the burden on the community. The accidents caused by drug addicts at work are 3- 10 times higher than those of normal people. Case 28: Jiang, an unemployed young man in Tengchong County, Yunnan Province, often steals money from his family to buy drugs after becoming addicted to drugs. Once he had a drug addiction and forced his father to take out money to buy drugs for him with a knife. If his father didn't give it, he inserted the knife into his chest, and his father agreed to give it and pull it out. Case 29: Chen Mou, Shajing Town, Baoan County, Shenzhen City, Guangdong Province, 1979 (age 15) came to Hong Kong illegally and became addicted to drugs. 1987 was sent home by the Hong Kong police. His father in Hongkong gave him 300 yuan money every month, and soon he married Miss Peng. He often steals money from his wife to take drugs, and also steals money from grocery store owners, extorting HK$ 5,000 from his grandmother, HK$ 5,000 from her, HK$ 5,000 from his mother, repeatedly extorting from his grandmother, sister and brother, and threatening to set fire to kill people. The parents couldn't bear it, strangled him and put the body in two sacks and threw it into the wild. After the incident, more than 0/00 local cadres and masses signed a letter asking for leniency, saying that "their parents put their righteousness above their family, which harmed the place and the people." 3. Harm to society and future generations: According to the report of the World Health Organization, 1980-89, about 654.38+million people worldwide died of drug abuse, and at least100000 people lost their normal intelligence and ability every year due to drug abuse. About 25,000 people in the United States die from drug abuse every year. 1990, Americans spent1800 million dollars on cocaine,1200 million dollars on heroin, 9 billion dollars on marijuana and 2 billion dollars on hallucinogens and amphetamines. Some people in the US Congress estimate that the total annual expenditure on illegal drugs is $654.38 billion+$000 million. New york Mayor Dinkins revealed at the special session of the UN General Assembly on drug control on February 20th that 165438 in some hospitals in this city, 1-20% of newborns were positive. Drug abuse can also cause other crimes, such as theft, robbery and murder. According to a survey in new york, 56% of murders are related to drugs. Drug abuse for non-medical reasons can only be maintained by criminal means. Although drug abuse itself will not make drug addicts more aggressive and violent, lack of drugs will lead to crime and violent activities. The most common is stealing. Most, almost all young drug addicts grew up in the worst slums of cities where juvenile delinquency is rampant. 1990 Among the 1 12 criminals captured in Kunming in May, there were 66 drug addicts. In order to get money, a drug addict stole four "Beijing" jeeps for heroin within six months. Drug addicts ganged up to steal and committed 36 crimes in a few months. Another example is that Zhao spends 200-300 yuan on heroin every day, 6,000 yuan a month, and all the 40,000 yuan stolen in half a year is used for drug abuse. In particular, drug abuse has contributed to serious drug crimes. Drug consumption promotes drug production and sales, making the underworld profitable. Imagine that if no one in society consumes drugs, all the criminal acts of planting, processing, selling and selling drugs will be difficult to develop.

Why do drug addicts lose weight gradually? Please thank everyone, because the excitability of drug addicts increases after taking drugs. The acceleration of heartbeat-pulse-breathing and metabolism promotes the acceleration of nutrient metabolism and the reduction of nutrient accumulation, especially the reduction of fat, so it will gradually lose weight.

How can a new addict tell? Thank you, everyone. Then why don't you ask your smokers how to tell the difference!

Can children often bite pens lead poisoning? Please thank you. No matter what is in the pencil, biting it is not a good habit. In addition to lead poisoning, it will also affect the development of teeth. The germs on pencils will also increase the chances of children getting other infectious diseases.

Please accept it, thank you!

What diseases can frequent smoking produce? Ladies and gentlemen, thank you for the harm that smoking does to your health. Smoking is an unhealthy living habit. The harm of smoking to human body includes: smoking in the brain can cause various brain diseases, reduce oxygen and blood circulating in the brain, lead to cerebral vascular bleeding and occlusion, and lead to paralysis, mental decline and stroke. The cause of stroke is cerebral vasospasm caused by smoking, which makes blood coagulation easier. Smokers are twice as likely to have a stroke as nonsmokers. Laryngeal smoking can cause laryngeal cancer. Laryngeal cancer patients are mostly male. Smoking can accumulate fat in the heart and blood vessels, block blood vessels, and make smokers prone to coronary heart disease. The death rate of heart disease caused by smoking accounts for 25% of the total. The prevalence of smokers over 50 has doubled. The prevalence rate of smokers under 50 years old increased 9 times, reaching 14 times. Smoking will constrict blood vessels, slow down the circulation of blood and oxygen, and eventually lead to thickening of blood vessel walls, which will lead to coronary heart disease and stroke. Smoking will completely block the blood circulation of hands and feet, leading to amputation. Smoking in the lungs can cause lung cancer. 90% of the total mortality rate is caused by smoking. The prevalence rate of a person who smokes ten cigarettes a day is ten times that of a non-smoker. Damaged cells can't return to normal. The initial symptoms will not be found until the cancer cells spread to blood vessels and other organs. Smoking can also lead to emphysema, and toxic substances accumulated in the bronchi of the lungs will hinder the normal ventilation of the air inhaled by the human body, make lung cells expand or rupture, and lead to dyspnea. For people with gastrointestinal diseases, smoking is enough to make them worse. People with gastric ulcer or duodenal ulcer will slow down the healing of ulcer and even become chronic diseases. Smoking will affect the nervous system, accelerate the secretion of saliva and gastric juice, make the gastrointestinal tract often tense, and lead to the loss of appetite of smokers. In addition, nicotine can also contract gastrointestinal mucosal blood vessels and reduce appetite. Bone smokers have a longer fracture recovery period than non-smokers. It may be that nicotine and carbon monoxide contained in cigarettes slow down the process of bone regeneration. Nicotine constricts blood vessels and reduces blood flow to new bones. The carbon monoxide inhaled during smoking also reduces the speed at which oxygen enters the body. Smoking can lead to osteitis and back pain. Smoking more than ten cigarettes a day will double the prevalence of periostitis. Most people with severe back pain are addicted to smoking, because smoking will reduce the blood flow of the articular disc and the articular disc will degenerate early. Smoking can lead to arthritis. Smoking a pack of cigarettes a day will increase the prevalence rate by 50%. Female smokers are more likely to suffer from fractures and joint diseases after menopause. Smoking will lead to faster bone loss. Women smoke a pack of cigarettes every day from adolescence to menopause, and their bones are 5% to 10% less than those of non-smokers. When smokers enter menopause, the bone loss rate is faster. Smoking can interfere with estrogen, which is an important hormone in bone development. Bronchial smoking is the main cause of chronic obstructive tracheal disease. Because smoking will lead to short and irregular cilia of bronchial epithelial cells, and it will cause dyskinesia, reduce regional resistance and be susceptible to infection. Smoking in the liver will increase the burden on the liver. Regular smoking will affect the lipid metabolism of the liver, increase blood lipid, decrease benign cholesterol and increase malignant cholesterol. This has caused the burden of detoxification function of the liver to increase. Intestinal smoking can lead to colon cancer. The risk of this kind of cancer is directly proportional to the amount of smoking. Research shows that although quitting smoking can reduce the risk of other diseases such as heart disease and lung cancer, the risk of colon cancer is still high. Eye smoking can lead to cataracts and affect vision. Research shows that there are twice as many cataract patients who smoke more than one pack a day as those who never smoke.

Smoking can cause stomachache? Thank you, everyone. According to statistics, the probability of smokers suffering from gastric and duodenal ulcers is two to three times that of non-smokers. Among smokers, 20% to 30% of those who smoke 10 cigarettes a day may suffer from gastritis, and 40% of those who smoke 20 cigarettes a day may suffer from gastritis. 12543

Can eating poisonous water cause cancer? Thank you, everyone. Hey. . You'd better give it up quickly. Anyway, health is the most important. As long as it is poison, no one will be good to people. If it does not lead to cancer, it will lead to other diseases.

Can frequent * * * lead to infertility? Thank you, everyone. No, you don't have to take birth control pills.

Are there any pale and emaciated drug addicts? Thank you. It's impossible. 1) Toxic effect of drug abuse on the body: Toxic effect refers to a harmful effect on the body due to excessive dosage or long medication time, usually accompanied by dysfunction and histopathological changes of the organism. The main features of poisoning are drowsiness, insensitivity, dyskinesia, hallucinations, delusions, disorientation and so on. (2) Withdrawal reaction: It is a serious and potentially fatal physical and mental damage caused by long-term drug abuse, which usually occurs after sudden withdrawal or reduction of dosage. Many drug addicts died of various complications caused by severe physical withdrawal reaction, or committed suicide because they could not stand the pain and had no financial resources to buy drugs or take drugs. Withdrawal reaction is also an important reason why drug addicts are difficult to quit. (3) Mental disorders and metamorphosis: The most prominent mental disorders caused by drug abuse are hallucinations and thinking disorders. Their behavioral characteristics revolve around drugs, and they even lose their humanity because of drug abuse. (4) Infectious diseases: Intravenous drug abuse brings infectious complications to abusers, the most common being purulent infection and hepatitis B, as well as worrying AIDS problems. In addition, it also damages the nervous system and immune system and is prone to various diseases. (1): Physical dependence is a strong dependence caused by repeated medication. Physical dependence: drugs act on the human body, making the human body adapt to changes and forming a new equilibrium state under the action of drugs. Once the drug is stopped, the physiological function will be disordered and a series of serious reactions will occur. This is the so-called withdrawal reaction, which makes people feel very painful. In order to avoid withdrawal reaction, drug addicts must take drugs regularly and constantly increase the dose, so that drug addicts can not live without drugs all day. (2) Psychotropic drugs act on people's nervous system after entering the human body, which makes drug addicts have a strong desire to take drugs and drives them to desperately seek and use drugs. Once mental dependence occurs, even after detoxification treatment, it often takes months or even years to fully restore the original physiological function after the withdrawal reaction in the acute stage is basically controlled. . More seriously, dependence on drugs is difficult to eliminate. This is the reason why many drug addicts take drugs again and again, and it is also an urgent problem to be solved in the world medical community. (3): Harmful mechanism of drugs to human body At present, heroin is the most popular and harmful drug in China, and heroin belongs to opium lamp drug. Endogenous opioid peptides and opioid receptors exist in normal brain and some organs. Under normal circumstances, endogenous opioid peptides act on opioid receptors and regulate people's emotions and behaviors. After taking heroin, people inhibit the production of endogenous opioid peptides and gradually form a balanced state under the action of heroin. Once heroin is stopped, they will have symptoms such as anxiety, cold and hot, goose bumps, tears, runny nose, sweating, nausea, vomiting, abdominal pain and diarrhea. The pain of this withdrawal reaction in turn urges drug addicts to do everything possible to maintain drug use in order to avoid this pain. Methamphetamine and * * * are central stimulants in pharmacological action, which destroy people's nerve center.
