They are always signs of cheating
Also, I would still insist on segregated competitions: natural and with use of steroids. Competitions are not about results only. It's not about the times of your laps. Those 9.77s for 100m sprint does not really mean anything in se. It's just a number. What matters is that number compared to other people. To reach these astronomically good lap times, you need to train hard and devote your life to the sport. If a substance exists that drastically reduces the effort necessary to reach a <10s lap time, and is widely used, then a <10s lap time instantly loses a lot of its value.
Do we have segregation based on diet? Training? Shoes? I think it's pointless to say "nothing else matters but drugs". Like I said before, can an average Joe who pops some steroids become a world-class athlete? Of course not.
And like I said before, the current training methods are anything but natural... I think you are injecting biased words into the discussion.
What do you think athletes do to get better? They push themselves farther and harder to go faster or be stronger. It's the same thing we've been doing for hundreds of years to stay alive.
If you want to say that hard work is unnatural, i'd say that saying that is unnatural considering how we've survived for centuries by training the exact same way. the only difference between us and cavemen is that we've developed more sophisticated ways of training.
Is it simply a question of impact? If so, and I know I've been saying this a few times, training is much more important than roids.
"More sophisticated" is an understatement. I can't imagine a caveman playing hours and hours of tennis every day.
Modern training is not at all 'natural'. Even for an average person in today's world, they don't understand the level of training needed to even compete on a national level, let alone on the world stage.
How long do you think people have been using drugs and chemicals to improve? The spartans famously treated newborns with alcohol to toughen the skin, how far back can drugs and supplements be traced? Is this merely a question of tradition?
I feel like the goal posts are moving quite a lot.
I don't think Steroids should stop being looked down upon. Yes it should be just what it is because Steroids is a thing that some people use to get buff. For Example: Professional Wrestlers need to sometimes get buff so that they are getting paid to do so.
