　　Teenagers that use Internet social networking sites like Facebook are more likely to end up addicted to drink and drugs, according to researchers.Scientists at the National Center on Addiction and Substance Abuse (CASA)

　　at Columbia University, surveyed more than 1,000 children aged between 12 and 17 via an online poll (民意调查) and another 1,000 by telephone.

　　They found

　　those

　　who

　　spent

　　any

　　time

　　on

　　social networks each day were five times as likely to smoke as those who didn't visit them.They were also three times more likely to drink alcohol and had double the chance of smoking cannabis (大麻)．

　　This survey suggested peer pressure (同伴的压力) was playing a large role, with 40% of all teenagers seeing pictures of friends getting drunk on sites like Facebook and MySpace.

　　Half of the teenagers who said they had seen pictures of people being drunk or using drugs first saw such images when they were just 13 or even younger.Those who saw these images were more than twice as likely to be able to get alcohol in less than a day and much more likely to have friends and classmates who abuse illegal and prescription (处方) drugs.

　　Joseph Califano Jr.who is CASA Columbia's Founder and Chairman and former U．S.Secretary of Health, Education，and Welfare, said，“The relationship of social networking site images of kids drunk, or using drugs and of suggestive teen programming to increased teen risk of substance abuse offers some confirmation of the saying that a picture is worth a thousand words.The time has come for those who operate and profit from social networking sites like Facebook to use their technology to limit such images and to resist use of their sites to children and teens who post pictures of themselves and their friends drinking or using drugs.Continuing to provide the electronic vehicle for transmitting such images contributes to electronic child abuse.”

　　He said parents are often in_the_dark when it comes to the risks.He said an accompanying survey of nearly 500 parents found 86% did not think social networking sites would increase the risks of drinking alcohol.
