ok, will try and be specific.
a.) Could you still define what "competitive athletes" are in your mind?
There are some problems in what i am saying as many non-athletes take illegal drugs just to look good, pick up, or even enhance their stage presentation (strippers, actors).
So, nowithstanding this problem, i refer to competitive athletes as those who compete in an organised sport where there are rules, federations and so on. It can include bodybuilding and all competitive sports where drugs can be performance enhancing.
b.) In terms of objective - it is the health dangers posed by drugs (I assume you are not just talking about steroids here) that you want to see avoided by having drug testing. The logic being that if people know they will be tested rigorously in and out of competition then they will avoid taking drugs (banned drugs that is)?
I think if there is an effective random and in-comp drug testing program, even with low rates of testing, this would have a major impact.
Again, it could be argued that other drugs are more dangerous for health, but i am focusing on performance enhancing drugs that give users will have an immense advantage. I know of many who have suffered health problems, although i recognise that relatively safe usage can occur, at least amongst the sane more likely to be infleunced by logic.
Again, all i am saying that tougher testing can be introduced, which I would personally support if I was asked as part of a community.
