I think you are ignorant of the issues that I and a lot of other people face every day. I can see a clear difference, just between my 3 kids. 2 don't have it, one does. You don't know what you are talking about.
I respectfully suggest that it is you who needs to further educate yourself on this matter. ADD is an excuse for massively widespread child abuse, nothing more. Disorders that affect millions do not just appear out of thin air.
There are real disorders that affect children and are diagnosed as ADD, but I would estimate that those are less than 5% of all such cases.

This problem is REAL. Over diagnosis of children with this condition is more related to teachers issues.
As for me, RITALIN made it possible for me to stay focused. I never got a buzz from it. I just finally felt normal.
People who don't need it would be bouncing off the walls if they were taking the stuff.
