Is ADD a real sickness that needs medical treatment?

Background: I am a 20 year old college student, I see more and more of kids with ADD taking pills. Every time a kid is doing a little off in school parents figure their must be something wrong with their kid so they bring him to the doctors. I do not have ADD, and everytime I'm not focused I just realize that I have to do said task. Growing up with out ever having ADD problems, I do not know what it is like. I just feel the medicine is not needed.

Redditors that have ADD, do you think you could focus fine without taking medicine?
