Activity flow:

The teacher said: drugs are a public hazard to mankind. It not only harms the health of people, especially teenagers, but also seriously threatens social stability and affects economic development and social progress. In the modern history of China, drugs brought great disasters to the Chinese nation. Nowadays, the drug problem has become a global problem, and it is called the three major public hazards in the world together with terrorism and AIDS.

(1) Drug types:

According to Article 357 of the Criminal Law of People's Republic of China (PRC), drugs refer to opium, * *, ice, morphine, marijuana, cocaine and other narcotic drugs and psychotropic substances that can make people addicted.

Auxiliary materials:

1. Opium: Opium is taken from the fruit of poppy, and the white pulp that flows out is oxidized and dried in the air, which is opium. Opium contains 20 alkaloids, of which the content of morphine is about 65438 00%. Long-term smoking can make people lose weight, physical fitness, immunity and infect various diseases.

2. Morphine is a white needle-like crystal extracted from opium. It has a strong inhibitory effect on respiratory center. Excessive breathing will lead to slow breathing and even paralysis of the respiratory center, which is usually the direct cause of death from morphine poisoning. Morphine is more addictive than opium.

3.* * *: commonly known as white powder, it is made of morphine and other chemicals. Extremely addictive. Long-term use or injection of * * * will make people lose weight, narrow their pupils, decrease their immune function, be prone to viral hepatitis, lung abscess and AIDS, and be extremely difficult to quit.

4. Ice: The scientific name is methamphetamine or ice. It is an amphetamine stimulant, odorless and bitter translucent crystal. Taking methamphetamine will have a strong stimulating effect on the central nervous system, and long-term use will lead to brain damage. Smokers often commit suicide and self-harm because of schizophrenia.

5. Ecstasy: MDMA, a scientific name, is an amphetamine-type stimulant with strong central nervous system excitation and strong mental dependence. If taken for a long time, it will seriously damage people's central nervous system, lead to hemiplegia, and easily make smokers' behavior out of control.

6. Cocaine: The chemical name is benzyl germ alkali, which is the strongest natural central stimulant. A small dose of cocaine can slow down the heart rhythm: after the dose is increased, the heart rhythm is accelerated, and shortness of breath, vomiting, tremor, convulsions and other phenomena may occur; if the dose is large, it may lead to death.

(B), the dangers of drugs (student discussion, teacher summary)

1, drugs destroy people and health: digestive function, nervous system, respiratory and circulatory system, infection with "AIDS".

2. Drugs make people lose everything, and the family is ruined.

Drug abuse leads to corruption and crime.

4. Drug abuse harms the society and becomes a public hazard in the world.

(3), drug addiction (watch the case)

Drug addiction is a strong desire for drugs. Repeated use of drugs in order to get pleasure or avoid pain puts drug addicts in a special mental and pathological state, which can be divided into mental dependence and physical dependence.

Mental dependence: also known as psychological dependence, this is a special neurological effect produced by drugs acting on the central nervous system. Drug addicts have a strong desire to pursue drugs, forcing drug addicts to desperately seek drugs to satisfy their desires.

Physical dependence: also known as physiological dependence, is an adaptive state of the central nervous system for long-term use of addictive drugs. At this time, the body must maintain a sufficient amount of drugs to maintain its normal state. Once the drug is stopped, the physiological function will be disordered and a series of serious reactions will appear, which are called withdrawal symptoms. Take * * * as an example, its withdrawal symptoms are yawning, watery eyes, runny nose, goose bumps and sweating.

(4), why drug addicts are mostly teenagers:

1, teenagers are simple and ignorant, curious and conformity. One person smokes and everyone tries.

2. In the process of growing up, you will encounter setbacks, strong rebellious psychology, spiritual emptiness and temptation, and seek excitement in drugs.

3. Pursue fashion blindly and regard drug abuse as fashion.

4, weak self-defense ability, unable to refuse the temptation of poison.

5, credulous prejudice that drugs can improve performance and treat diseases. ...

(5), several antivirus methods

1, the straightforward method-refuse to seduce resolutely and directly: "Drug abuse will be addictive, harm others and harm yourself, don't hurt me.

2, the golden cicada shelling method-if the situation does not allow. Or coerced, you can politely refuse: "I, I have a stomachache, I have to go to the toilet." And run away.

3. Take the initiative-immediately put forward counter-suggestions, such as swimming together and watching a ball game, to change the subject: "What's so good about these things? I have two tickets, so let's go to the movies together.

4. Secret reporting method-If you really can't leave, tell the person you depend on secretly when people are not paying attention, or call 1 10, and the police uncle will help you quickly.

5. Inform your parents in time-when drug dealers force you to take drugs and threaten you, don't tell your family and teachers, otherwise don't be intimidated by them when you or your family are about to start work. Tell the teacher at the first time.

Sixth, students discuss and summarize.

Teenagers' understanding of drugs is still naive, and the situation of drug control among teenagers is still very grim. In this case, we firmly believe that through the efforts of the whole society, no suspicious elements will be given an opportunity, and relying on mutual trust and unity, all suspicious criminal channels will be blocked. Finally, we can see a world without pollution, and people share a beautiful peace.
