The Federal Government's National Institute on Drug Abuse (NIDA) estimates that 30 percent of all college students will try cocaine at least once before graduation. Other research by the National Survey on Drug Abuse shows that the age group of 18 to 25 is the one most likely to use illicit drugs. Because of the pressure and adulation that often accompany sports success, college student athletes may be particularly vulnerable to drugs. A small percentage turn to drugs in an effort to enhance their natural abilities. Amphetamines are used in an attempt to prevent or delay fatigue, mask pain, and increase self-confidence and aggression. Anabolic-androgenic steroids are used to increase strength and muscle mass. Sterility, alterations in sex drive, weight gain, and enlargement of the prostate gland are just some of the adverse side effects. Marijuana, an illegal drug, is believed to enhance athletic performance but, in fact, it has been proven to reduce the ability of the user to perform any function that requires concentration. Cocaine, the dangers of which are well-known in the sports world, increases blood pressure, heart and breathing rates and body temperature, which combine to give the user a false sense of confidence and enhanced energy. Alcohol is a depressant that impairs speech and coordination, diminishes inhibitions, and causes a loss of judgment. Other drugs such as hallucinogens, heroin, caffeine, and nicotine are discussed. The use and misuse of these drugs to enhance athletic performance violates the very principles of fair competition and can result in severe physical, emotional or psychological problems. Some signs of drug abuse are social withdrawal, mood swings, and abrupt changes in attendance at school or practice. Drug awareness education programs for student athletes and the community are recommended.
