I think the government has already done lot to prevent the teenager to drug. Such as the voluntary school-based drug testing scheme, maybe it is not very effective. The main problem is the teenagers do not share the worries to their parents or teacher but friends. Some of their friends try to encourage them try drugs. At last they cannot escape drugs. Also nowadays student get more and more pressure from their study since their parents tell them study is the only way to success. Furthermore the society also gave pressure to the student. That is the more and more teenager drugs.

Drugs is something that i have never tried
However, there are lots of samples showing in front of us
It is obvious that taking drugs is an irreversable way in our life
It lets our parients , teachers and friends down
It is strongly advised that we should calm down when we are at a lost and find some people to help us solve our problems ,but not taking drugs to gain a little happy period followed by a long horrible life time

People who take drugs are just silly.
There are many students smoking on the streets with their uniform on. So what! they think.
Who would be blamed for if students are found smoking or taking drugs? Their parents or their teachers?
We should do what we can do. but sometimes, when they are out of our sight, what can we do?
There are so many ways to reduce stress. Taking drugs isnt the only way. Dont use "having so much stress" as an excuse to take drugs!
It isnt that cool.
