All eyes are on London with the opening of the Olympics, but where there are high profile athletes, the conversation soon turns to performance enhancing drugs.

The World Anti-Doping Agency says the London games will be the most dope-tested in history, and has already spent roughly $30 million on drug testing and enforcement. Wealthier countries usually have a competitive advantage when it comes to athletics. More money to spend on sports means better training facilities and coaches, and more money for equipment like expensive aerodynamic swim suits.

But are wealthier countries better equipped to cheat, both within and outside of the rules, as well?

The Olympics and other athletic competitions strive for a level playing field between all competitors, and are spending up to roughly $30 million on tests and enforcement of anti-doping in the 2012 Olympic games to maintain balance ? but gray areas still remain. Several athletes train and sleep in hypoxic chambers that mimic high altitude, which boosts an athlete's red blood cell count, increasing endurance and recovery time. Such a chamber runs from $7,000 for a small tent, to $25,000 for a room, according to the Huffington Post. In 2008, medal winners in swimming were dominated by athletes who wore aerodynamic swimsuits that ran over $500, and needed to be replaced after five uses.

It may or may not be ethical, but as of now, it’s allowed. Those price tags are simply unaffordable for poorer countries.
