    What would you do if a stranger gave you some medicine and it would keep you slim or help you do

well in exams? Would you take it?

    Students at Shenzhen Luohu Foreign Language Middle School have learned to keep themselves safe

by saying "no". In fact, what those strangers want to give them are drugs (毒品). Drugs are dangerous

to your health!

    "Because teens don't know much about drugs, they might want to try them," said Zhang Dongsheng,

the director of Shenzhen Drug Control Office.

    Now, many schools arrange courses or organize some activities to help students know about drugs.

    Liang, 16, was a good student before trying drugs. One day, some old friends told him it would be

fun. After taking drugs only once, he found it very hard to stop. Liang began to spend all his time and

money on drugs. Soon, he stopped going to school and started stealing. In the end, he was put in prison.

    In China, taking drugs is becoming a big problem for teens. According to a survey, about one million

people in China were using illegal drugs last year, and 72% of them were young people. Worse still, there

are about10,000 drug users under 16 now.

    Zhang has some good advice on staying clean. He said, "Drugs are dangerous. Never try them, even

if you're curious! It is the most important for you to keep safe and healthy."
