The statistics are pretty scary: (12)Each year 2.8 million college students drive drunk and 1,700 die from alcohol-related injuries. Nearly half a million engage in dangerous sports, and aimost 100,000 students are victims of alcohol-related assault. But alcohol isn’t the only substance that’s a problem. Use of other drugs other than heroin is back up to high levels among college students and there’s a newer trend causing concern: (13)29 percent say they have used prescription drugs just for fun. These include pain relievers like Vicodin,(13)which can lead to respiratory and liver failure, and amphetamines such as Ritalin and Adderall,(13)which can result in cardiac arrhythmia and coma and can lead to harder drugs. Students using these stimulants are 20 times more likely to try cocaine.(14)Part of the problem is that these prescription drugs are so easy to come by—many college students have prescriptions for drugs like Adderall and Ritalin and are willing to sell them, says Sue Foster, vice president and director of policy research for the National Center on Addiction and Substance Abuse at Columbia University. "Many(of these drugs)are just there for the taking in medicine cabinets across the country," Foster says.
     (15)Ironically, while drug use in high school is also on the increase, drinking there is at an all-time low. According to one latest survey, fewer than half of last year’s incoming college freshmen say they drank beer as high school students.
