It's always great when people compare learning disabilities to being dumb.
> performance enhancing drugs
I realize that it's easy to look at how stimulants affect people without ADHD and conclude that they're getting the same advantage but this really isn't true. A non-ADHD med example is caffeine. Most people who down a few coffees or energy drinks will be wide awake and jittery. But for me I'll be hyper and bouncing off the walls and spacing out until I have an energy drink which lets me focus a little bit and makes me sleepy.
The point is that not everyone gets diagnosed and has equal access to performance enhancing drugs and extra time when taking a competitive test.
