I love this question and am so glad it got brought up.
The simple, clear answer is a resounding yes.
We keep hearing talk of "leveling the playing field." Okay, that's great in theory, but let's look deeper. Many of the athletes we see being busted for PEDs are being busted for what? AAS and HGH. Sure we have amphetamines and other things, but we'll talk about those later. With AAS, let's look simply at testosterone. What does it do? It provides an exogenous source of a hormone already in the body. So that person is obviously at an unfair advantage to those not using it, right? Well yes, but it's not that simple. What about TRT/HRT? What about 40 year old guys hanging onto the game vs. the 19 year old fresh out of 1 year of college? And even two individuals of the exact same age -- not every one person is exactly the same! At the highest level it's unlikely that you're some schlub with low-T and hanging with the big dogs, but it's not impossible.
So what does (MLB, for example) base this PED testing on? A threshold. Are they using the same labs that most of us see with a range of something like 300-1,100 being the "normal" range for total testosterone? If someone hits 1,150 does he get flagged? I don't know what their specific testing methods are for compounds that are naturally occurring (I know obviously they have steroid tests for anything that's synthesized and wouldn't normally exist in the body). But what if we have Player A and Player B and each is PED-free, but Player A has a total test of over 1,000 and Player B is barely on the "normal" side at 400? Is that a level playing field? No, it's not. But it's not wrong, either. Theoretically if you take the D off of PED, we're looking at anything performance-enhancing and why should we draw the line here? What if someone has a rich family and more access to trainers and medical labs to ensure he is at 100% top of the line whereas a Cuban refugee player has nothing?
The point of all of this is it's murky. There is no way to ensure that everything is 100% even. And there shouldn't be!
So when it comes to sports, here's the deal -- if something is still federally illegal, then you certainly shouldn't be encouraging its use. But it also doesn't need to be your place to do the testing. The whole MLB steroid debacle with congress was an absolute joke. You want to know the only reason they did it? Because congress wanted to be involved with superstars and athletes. There are WAY bigger problems like human and drug trafficking, our economy, etc., but no, they'll have a government stoppage before dealing with any of those and they'll certainly find a way to poke their nose into MLB and NFL.
And, if leagues really wanted to test players, it should be a weekly, monthly, whatever increment testing that absolutely ensures every player is tested. Not some "we're going to strike fear in them by randomly testing some people a couple times a year and that way they'll all stay clean but we really know they won't" system.
And lastly (for now lol -- I could talk about this forever), the whole role model to children thing is out the window. A.) PEDs are not the devil. So that shouldn't be a concern. That's part of the problem! That's why most of the general public if you were to tell them you took Superdrol, which is now a banned substance, even though it was legal at the time, they'd be all "OMG STEROIDS YOUR BALLS ARE GONNA SHRINK AND YOU'RE GOING TO BEAT YOUR CHILDREN!" So yeah, let's move past using a substance (in a responsible way) is a bad example to kids when utilized by an adult. B.) These players are setting far more bad examples out there. We've got players killing people, beating women, punching teenagers over beach chairs (and that was a coach!), cheating by altering game equipment, and plenty of other stuff. Let's not overlook the guys who cuss out umpires or swear when the parabolic mic picks it up and walk up to rap songs that are often so explicit the sound tech. has a hard time finding a 12 second snippet he can actually use. The crimes are obviously crimes, but the other things are just personal preference -- not what I'd want my kids to be seeing/modeling, but that's up to each individual to decide. Point is, there are plenty of other things at play when it comes to being examples to children. And finally C.) we need to find role models for children who aren't just athletes or movie stars. In any category in life, there are good people and not so good people; we can't make a sweeping generalization that everyone from any particular group is the same. But I've heard this argument a long time and probably made it myself. As I've grown older and get ready to have kids of my own, I know I'll be looking at it from the standpoint that we're all human beings and if there's a good one who is an athlete, then good for them and my kids should respect him or her. But I want my future kids to care about other things, like the doctor who builds a hospital in Sudan so that children who are dying can receive medical treatment; the scientist who develops a way for blind children to have sight. I've learned that I put way too much care into sports than I ever should have. Sports are great for so many reasons, but there are other things that are very important that we neglect giving attention to and I want to do a better job of that. So yeah, as far as the role model excuse, I don't care about it.
Also -- people are out there doing it already anyway; don't you just want to see the biggest monsters out there? If you didn't, you'd only watch the WNBA and youth level sports and not much at the pros. I say juice them all up and let them compete for all of our enjoyment.
