> Interestingly enough, many people can easily mistake untreated ADHD (or not adequately controlled) with cocaine and stimulant use, especially hyperactive type. Cocaine and stimulant use in people without ADHD obviously causes that issue (cocaine use), along with some other problems (euphoria, lack of empathy, megalomania, sleep problems).

This is true but I should point out that "normal people" taking stimulants won't necessarily get hyper. You might get more calm and focused too. Claiming that Adderall works differently on ADHD people is a sort of marketing technique to stop it from getting banned entirely (like it is in Asia), because otherwise even more people would be trying to use it as a study drug.

Somehow modafinil has a reputation as a wonder drug that works on everyone, even though the way it works is not very different.
