While I'm sure there are some (many?) people faking it for accommodations or drugs, I assure you that ADHD is real. I know several people with ADHD who have struggled to find the right combination of medication to even get to a state where they can lead functional lives, which is still not what us neurotypical folks would call "normal".

terrible take, it's ruined otherwise amazing potential countless times. Just see how over-represented ADHD is in the prison population

I suggest you read the book "Selling Sickness" and revise your take.
