Stop Drug Testing of Professional Athletes?

My nine year old nephew was listening to a conversation about someone being sick and having to take steroids. He said, somewhat enthusiastically, "Steroids?" "The kind that the baseball players take that make them big and strong and play baseball better?" Someone quickly said "No, the medical kind."
This only reinforced my opinion on testing professional athletes for drugs.
They shouldn't do it. Just think if you owned a company that made steroids. How many millions in advertising would you have to spend (If it were allowed) to get kids to say "The kind that the baseball players take that make them big and strong and play baseball better?" But they don't have to spend a dime on advertising because of the drug testing policies of professional sports teams. They should stop testing professional athletes but there should be a clause in their contracts stating that they can't disclose any substances that they take. This is only for those that are more concerned about the safety of the children that look up to them than fairness in record setting. Personally I'm much more concerned about the children.
