I think you'd be throwing people with ADHD under the bus which is infinitely worse than letting some fakers get their hands on stimulants. Improve the diagnostic process if needed, but first you have to prove that it's insufficient. I'm not aware of any studies supporting these claims.

No. Not all drugs are effective for everyone, this includes different stimulants.
