How to write a host speech for the class meeting entitled "Drug Control"?

The serial words of the program are connected in series by the host during the program. In today's various performances and assemblies, the host often becomes the protagonist, and the host's speech on the stage is the soul of the assembly.

Dear students, good evening!

I'm Zhang Zhentao, the host of today's class meeting. This class meeting is mainly to popularize drug knowledge and understand how to refuse drugs. Well, before it's too late, let's enter the first link "understanding drugs". I don't know. How much did the students know about drugs before this? Please look at the big screen. What kind of plant is this?

Yes, it is the famous poppy!

Poppy, broomcorn millet, stems, leaves and sepals are covered with white powder, and the flowers are large and scarlet. Next, let's look at the drugs extracted from poppy!

Guess what this black one is? (on the big screen)

Yes, he is the notorious opium, also known as opium.

I believe everyone knows. After the Industrial Revolution, the British bourgeoisie tried its best to sell industrial products to China in an attempt to open the door to China through commodity trade. Unable to do this, Britain resorted to despicable means and relied on the method of "extermination" to smuggle a large number of special commodities-opium to China to satisfy their infinite desire for profit. 1840 when the first opium war broke out, China was defeated and forced to sign the first unequal treaty "treaty of nanking" in modern times. 1856, when the Second Opium War broke out, China was defeated again and was forced to sign another unequal treaty, Tianjin Treaty.

Please look at the picture below. People become listless because of smoking opium. Drug abuse not only harms the physical and mental health of China people, but also damages social productive forces, leading to the depression and decline of industry and commerce in the southeast coastal areas. Quitting smoking and detoxification is no longer a personal matter, but has risen to the national level, which also applies to us today!

Besides opium, poppy can also extract morphine!

There is also heroin, which is called the king of drugs in the world. Do you know that the famous detective Conan also has an episode about heroin? Heroin is the most popular drug in modern society.

Having said that, we have to explain the classification of drugs by the World Health Organization. Opium, morphine and heroin are classified as opioids by the World Health Organization. So, how many categories does the World Health Organization classify other drugs? Does anyone here know? The World Health Organization classifies drugs into eight categories: alcohol sedatives, opioids, amphetamines, cocaine, marijuana, hallucinogens, volatile compounds and nicotine.

Next belongs to marijuana-marijuana.

Next, it belongs to amphetamines.

Let me tell you the general results of taking methamphetamine. Because of the horror, I wrote a little. After taking methamphetamine, it will produce strong physiological excitement, consume a lot of physical strength, reduce immune function, seriously damage heart and brain tissue, and even lead to death. Addicts can also cause mental disorders, showing paranoia and aggression. After taking methamphetamine, it will induce sexual excitement, and it will not choose a partner, just for freshness and morality. Just as Pandora's box is opened, it will be beyond redemption, and the ugly side of human nature will break through the warning line of morality and ethics and get closer to animal nature. Therefore, it is very common for men and women to have chaotic sexual relations, promiscuity and collective fornication after roller skating. The consequences are naturally all kinds of sexually transmitted diseases, AIDS and so on.
