2)If people with ADHD are immune to getting high from it, that caveat of "at the reccomended dose" to prevent addiction wouldn't need to be applied. The only drugs people go ham on are the ones that get you high. Therefore, it is known by the medical community that recreational levels of these drugs do in fact get people with ADHD high.

Most people diagnosed with ADHD were diagnosed as children. Its highly doubtful that they were already addicted to adderall and then faked their symptoms to get a prescription.
its a party drug maybe for people who are too young to legally get into venues where actual party drugs exist. Maybe for a DND party. But a real party or venue? No. I understand fent has hit the streets hard, and perhaps that is pushing people who never experienced real party drugs into safer alternatives, as adderall is percieved to be. There may be a generational gap between us on this specific point.
yes, it creates focus in literally everybody who takes it.

I get it, the drug helps many people with ADHD, but the conversation can't only be framed as "people with ADHD can't get high or addicted to it," when the actual people who seek treatment for adderall addiction just so happen to be people who have ADHD. Nobody has ever lost their diagnosis because they got addicted to an addictive drug. I assure you of that.
