On recent Drug Tests

Due to the high number of doping instances in the last week I am being forced to write about this. First Edison Volquez is caught by MLB's testing system for a prohibited substance that is supposedly prescribed for a medical purpose. Then yesterday it is revealed that Lashawn Merrit was caught three times for DHEA, which is a banned substance, which apparently is part of a male enhancement medication. I want to commend MLB for implementing a suspension that is significant and not a puhover, but there is still more that can be done. The issue I want to bring up is that these drug testing programs seem to lack an important aspect of the international doping standards.The therapeutic use exemption(TUE) allows athletes with qualified medical conditions to use substances that are banned for medicinal purposes. This in no way protects athletes who are doping with a similar product. Manny Ramirez, Edison Volquez, and other athletes that have been caught by drug testing are not using TUE's to protect their careers from the impeachment of failing a performance enhancing drug test. I feel that the professional leagues that compete in the US need to follow the rules that are imposed on every other sport with a international sports federation. The banned substance lists from MLB, NFL,NBA, and NHL should be the same as the one used by all other sports federations and administered by the World Antidoping Authority so that international athletes are not going to get caught by a substance prescribed by a doctor that contains a banned substance. This issue affects the future integrity of our professional sports organizations.
