How do they test athletes for drugs?
Sometimes Athletes use those types of medicines which are banned in the sports.These medicines empowering the athletes performance rather than other athletes.In this way the game does not remain fair.For the fair game it is nesasarry to check that the athlete is not drug addicted.For that thing the boards and organigations do dope test of an athlete at a particular period of time.
Healthwise there is no blanket statement anyone can make about what happens to athletes who take performance enhancing drugs. Effects depend on how much, how often, and in what combination the drugs are taken. But when it comes to competitive sports the story differs. Laws have been passed forbidding athletes to use drugs for performance enhancement. And should an athlete be caught taking any they get disqualified from the meet.
