Oh good, another round of "ADHD isn't real."
I didn't say it's not real. A doctor prescribed me Adderall at 18 after talking to me for 5 minutes because I was having trouble sleeping. It did more harm than good.
Something can have therapeutic uses and still be over-prescribed.
The more interesting take for me is that these meds work roughly the same way and almost as well in people without ADHD (a symptom cluster, not a single disease per se, like everything else in the DSM). As we give them to people with ADHD why not let anyone get a scrip?
