No because unlike sport, which is artificial competition for entertainment, mental work is real productive work that benefits society. Increasing our mental abilities can make the the world a better place, the same cannot be said of steriods and sporting ability.

Another difference is that steriods at the level taken by athletes use is demonstrably harmfull for their health, this is not necessarily true for mental boosters.

"which is artificial competition for entertainment, mental work is real productive work that benefits society"

Uhhh, professional sport isn't 'real' work? I would would say without a doubt every single processional athlete probably works much harder then your typical white collar worker (due to the fact that they are not typical athletes) As far as "productive" goes, each pro organization is staffed with hundreds of people all doing 'productive' work which is possible because of the athletes that work for the corporation.

I have nothing against professional athletes. In fact I admire them a lot. But let's face it, sports is a zero sum game from the perspective of skill level. What real difference would it make to the world if all the world's athletes were 10% less fast/strong/coordinated etc...? Would people still be interested and entertained by sports - of course they would. In watching sports people like to see a contest of the best but the absolute standard of the best doesn't really influence that value. This is even more the case in sports participation. People like to feel they can compete at a particular level but it is all relative.

Now contrast this with mental abilities. If people can solve medical problems then they can prevent deaths and enhance health. If they can solve technical problems they can make peoples lives easier and allow them to achieve more. In general mental skills can make the world a better place. Not a zero sum game.

Sports is artificial competution under arbitrary rules. There is no benefit to people violating the rules. Using steroids in sports is like riding a bike in the marathon.

In contrast, regular "productive" work is not trying to be entertaining, it has other goals (e.g. moving packages from one place to another). If I ride my bicycle while delivering packages, more packages get delivered.

I think the mainstream attitude towards steroids is very hypocritical. If you're meant to play with what God gave you then surely athletes shouldn't even wear glasses! Tiger Woods had his vision surgically "corrected" to 20/15 (better than "normal") and no-one bats an eyelid (haha). Athletes regularly use the steroid cortisone to recover from injury, is that not cheating too? All anabolic steroids do is enable an athlete to train harder and recover quicker, they are not magic, you still need to put the work in, you can just choose to burn twice as bright for half as long.

There are sooo many downsides to anabolic steroids. Especially if you take them when you're young.

And cortisol is technically a steroid, but not the body-enhancing type that everyone refers to.

And steroids do allow you to train harder and recover quicker, but you still have to cycle off after 6-8 weeks... and then you go back to your original strength.

There are downsides to the pro athletic lifestyle, full stop. Why do you think there are so many teenagers in Olympic gymnastics? This is what I mean when I say hypocrisy; no-one has any problem with a 14-year-old winning their country a medal, who even remembers them when they're 24? The puritanical attitude towards steroids is inconsistent.

Sure, that may be bad, but steroids have much, much more downside relative to the other examples you have given.

Hard training at a young age can lead to amenorrhea and slowed hormonal development, but anabolic steroids cause irreprable damage to your liver and kidneys. And will ruin your joints.

There is no inconsistency here. It's not binary, it's on a gradient.

There isn't any medical evidence for that. Overuse of anything is bad for you. There is no medical reason that, if used under proper supervision, steroids should result in any long-term physical damage. In fact, as is the case with cortisone, steroids can improve an athletes chances of recovering from an otherwise career-ending injury. These aren't drugs remember, just more of what your body produces naturally. If you want to ban people from adjusting their hormonal systems in support of their lifestyle choices, you'd have to ban the Pill too.
