　　A survey done by the University of Michigan shows a big drop in the number of teenagers who say they smoke cigarettes.

　　In the survey, over 44, 000 students in Grades 8, 10 and 12, from 424 schools across the country were asked about their smoking habits. The results show that smoking among 8th graders went down from 21 percent in 2002, to 12 percent in 2007. In the same period, smoking dropped from 30% to 21 % among 10th graders and from 37 % to 30 % among 12th graders.

　　Anti-smoking organizations think educating kids about smoking risks are the cause of the drop. "These important drops in teen smoking did not just happen by chance, " said study director Lloyd D. Johnston. "A lot of individuals (个人)and organizations have been trying to bring down the high rates of teen smoking. "

　　Others say the higher price of cigarettes is an important reason teens are cutting back smoking.

　　Whatever the reason, the drop in teen smoking is good news to everyone, even cigarette-making companies who warn their product is only for adults, not kids. Health experts are particularly paying attention to teenage smoking habits because lifetime smokers often get hooked on smoking at an early age.

　　But some say that the new figures aren't exactly the cause for celebration. While it is true fewer teens are smoking today than five years ago, the rate of teen smoking is still very high.

　　Cigarette smoking is the leading cause of preventable death and disease in this country. "Our survey suggests that a lot of teens still do not understand the dangers of smoking, particularly the younger teens, " Johnston said.
