For far too long we've been __blaming individuals__ for their ADHD symptoms, and that's just created a broken system. And for far too long we've not taken ADHD symptoms seriously, and seen it as a phase.
The other point is, if people want to get these stimulants, why not? We actually understand them pretty well, and if they're not abused (e.g. you're not taking huge doses of them), they're fine.
And yeah, ADHD has always existed. But our lives weren't designed around making the symptoms of ADHD be something we have to deal with day to day. ADHD's impact is the worst on office based jobs.

Unrelated to the points I made above, but the recent more "understanding" of ADHD actually got me to go talk to a psychiatrist and got prescribed a stimulant based medicine for ADHD. I cried the first week I took it because it removed a fog from my brain that I had for my entire life.
I'm thankful that these discussions actually lead me to getting a diagnosis and medication.
