This would have been convincing if true, but is apparently false. Looks like the key difference is dose, at low doses stimulants aid focus and at high doses inhibit it (or something like that).

Interesting. I wonder if it would be possible to detect someone with ADHD by their preferred dose.

Come to think of it, the original test could still work. If we know that caffeine affects people with ADHD differently, the fact that it's because they're taking a smaller dose is irrelevant. It does mean that you're not allowed to control dosage, so it would be more prone to error.
