WADA can’t combat doping

Recently Alan Abramson wrote an article where he discussed whether tests conducted by the World Anti-Doping Agency (WADA) were reliable.
The WADA conducts more and more tests for steroids and other related medications each year. It seems that steroid users are caught. You may think that the world of sports and bodybuilding will be soon cleansed from intake of banned medications. For example, many tests for banned drugs have been conducted at the 2012 Olympic Games.
But several questions appear here. Are these tests sophisticated enough to catch any person that dopes? Are these tests effective?
Let meditate over results of several tests. In 2010 the WADA published statistics according which 258,267 samples were analyzed by 35 WADA-accredited labs. Out of these samples 4,820 results were atypical findings. About 60 % of positives indicated about usage of steroids. Numerous positives were for cannibinoids. 10 % positives indicated about application of marijuana. As you observe, only 60% out of those who administered forbidden medications applied steroids. Is it real? Don’t prove the results of the tests that the WADA doesn’t do the job properly?
Dick Pound, the former president of the WADA, thinks that at least 10 % of sportspersons who competed at the 2012 London Olympics used steroids. He confirms that those steroid users that are not clever are caught by anti-doping agencies. He also affirms that a sportsperson who has been caught using banned drugs will fail an IQ test. He adds that just unwise sportspersons don’t avoid detection.
So, when you hear that the WADA has conducted many tests to make sports clean, think whether these statements are true. Is able the WADA to make competitions fair? Why does the WADA publicize about number of tests?
It seems that the WADA just wants to convince people that the job is done properly. The WADA desires to secure future funds. This is the reality.
