　　As can be seen from the graph, there have been sharp changes in the age distribution of drug addicts. To be concrete, the teenage addicts only made up 10 percent of all the drugsters in 1982 while the ratio rose up to 65 in 2002.
　　The causes for them are not hard to find. First , teenagers’ fearless curiosity about everything new has led some of them into this marsh. Second, many of the young addicts turned for the first time to drugs for escape either from their failure in the national entrance exams or from their parents’ breakup. And above all, our education in the harmfulness of drugs has been far from adequate to build teenagers’ sound resistance to drugs. To sum up, the causes mentioned above must call for more of our concern, and effective measures should be taken to check the trend.
　　Obviously the drastic change will exert great impact on individuals and the whole society.

　　For one thing, drug-taking does great damage to the health of drug users.. For another, some drug users commit robbery or even murder their parents and relatives to get money to buy drugs, which poses a great threat to the social security and the social stability. Therefore, it is high time we did something to put an end to this trend.
