> Are you saying no one without ADHD takes prescribed medication?

No, I'm saying that the cognitive effect on function of someone without ADHD taking ADHD medicine isn't the same directionally as that of someone with ADHD taking it, the way the upthread proposed analogy of "a drug that increases IQ score by 25%" but which is only prescribed to those with IQ in the lowest quintile framed the situation. Excess dopamine impairs function in a different way that dopamine deficit, it doesn't increase it beyond what is seen with normal dopamine.

> If what you say is true, then the free market (black market) for adderall wouldn’t be so lucrative.

It is true, but the black market for adderall isn't mostly taking it for the same effect as people with ADHD are (some are, because there are still biases and access issues which prevent or delay diagnoses for people with ADHD, as well as deliberate, government-created supply shortages in the legal market.) But largely are taking it for wakefulness (an effect of dopamine surplus), and because dopamine surplus is part of the brain's reward system such that things which have been experienced which produce it are actively sought out. Again, this is why therapeutic dosages for ADHD are titrated to avoid going overboard.
