单选题Drug Overuse ① Nowadays,millions of people misuse and even overuse pain medications and other drugs. Research by the American National Institute on Drug Abuse （NIDA， 1999） shows that around 2% of the population over age 12 were using drugs non-medically. ② NIDA views medications as a powerful force for good in the contemporary world.

Although this abuse affects many people worldwide， particular trends of concern to the medical profession in the US appear among older adults， teenagers arid women. ④ Though it may be a surprise to many， the misuse of medications may be the most common form of drug abuse among the elderly.

In general， among women and men who are using either an anti-anxiety drug or a sedative， women are twice as likely to become addicted. In addition， statistics compiled for 12 —17 year olds show that teenage girls are more likely than teenage boys to begin overusing psychotherapeutic medication such as painkillers， tranquillizers， stimulants and sedatives.Among women and men who are using either an anti-anxiety drug or a sedative， the former are twice as likely to（）.Ateenage boysBfrom diseasesCget addictedDthe record of medicines overusingEuse instructionFare alien and utterly foreign
