Fight against doping should be stopped

Lance Armstrong never tested positive for any forbidden substance. But he was stripped of his seven Tour de France titles because the USADA accused him of doping.
You can notice that intake of prohibited preparations is claimed to be a last sin of professional sportspersons. They are banned, if they are found guilty or only suspected of doping.
For example, the British sprinter Dwain Chambers was suspended because he tested positive for tetrahydrogestrinone. This sportsperson affirmed that he was not the only Olympic  runner that used steroids. According to his affirmations, many sprinters of the US racing team took forbidden substances.
Some individuals are probably bothered by reading articles about fight against administration of forbidden products in sports. It seems that the war never ends. However anti-doping agencies put great efforts in order to eradicate doping from competitive sports, many athletes continue administering prohibited products. It is impossible to confront doping. It seems that it is better to legalize application of performance-enhancing drugs. Let athletes apply whatever they desire!
Sportspeople break greater records from one year to another. It will be needed to measure thousandths of a second in order to define who the winner is. It seems that it will be impossible to determine with a naked eye the fastest runners. That’s why some experts fear that it will be too difficult to keep sports interesting.
Several experts recognize that anti-doping systems fail. Athletes that have never tested positive for any prohibited preparation are sentenced to lifetime suspensions. Drug tests can’t promote catching those that administer steroids and/or other doping products.
Doping plays a great role in sports. Almost every winner of Tour de France has been involved in a doping case.
Fans have great expectations. Sportspersons have to push their bodies till the limits in order to win. They have to apply steroids and/or other performance-enhancing drugs in order to keep their reputations and not disappoint fans. The society should be blamed for athletes’ doping. Not only athletes should be demonized for usage of prohibited medicines. The society makes such culture where sportspersons can’t prosper without intake of certain preparations. That’s why it is necessary to discontinue demonizing athletes. It is better to permit doping in sports. Every sport must compose own list of forbidden medicines. Only substances that are harmful to certain sport itself should be banned. Let take the sport of boxing as an example. This sport must prohibit just those drugs which withdraw fear because removing of fear in this sport is against its nature.
