Athletes should be allowed to take any substances

The cyclist Lance Armstrong never tested positive for any forbidden substance. But the sportsman forfeited his seven Tour de France titles because the USADA accused him of doping.
You can notice that intake of forbidden substances is claimed to be a last sin of professional athletes. They are banned, if they are found guilty or only accused of doping.
For example, the British runner Dwain Chambers was banned because he tested positive for tetrahydrogestrinone. This sportsperson affirmed that he was not the only Olympic  sprinter that applied steroids. According to his words, many sprinters of the US racing team applied prohibited drugs.
Several individuals are probably bothered by reading articles about fight against intake of banned medicines in sports. It seems that the war never ends. Although anti-doping agencies try to eradicate doping from professional sports, numerous athletes continue administering prohibited medicines. It is impossible to eradicate doping. It seems that it is better to legalize application of performance-enhancing drugs. Let athletes administer whatever they want!
Sportspersons break more excellent records from one year to another. It will be needed to measure thousandths of a second in order to set who the winner is. It seems that it will be impossible to notice with a naked eye the fastest runners. That’s why several specialists fear that it will be very difficult to keep sports interesting.
Some specialists see that anti-doping systems fail. Athletes who have never tested positive for any banned medication are banned. Drug tests are not able to promote catching those that administer steroids and/or other performance-enhancing drugs.
Doping is an inseparable part of sports. Almost each athlete that won Tour de France was 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 administer steroids and/or other doping products in order to keep their reputations and not disappoint fans. The society is guilty of athletes’ doping. Not only sportspersons should be blamed for application of banned preparations. The society creates such culture where sportspersons can’t prosper without application of certain medicines. That’s why it is necessary to discontinue blaming athletes. It is better to allow doping in sports. Every sport must compose own list of forbidden drugs. Only medications that are harmful to certain sport itself must be prohibited. Let take boxing as an example. This sport must prohibit just those products that remove fear because removing of fear in this sport is against its nature.
