What is the difference between ADHD and non-ADHD ppl who take Adderall? - adderall compound

I am confused about the harmful physical effects of Adderall.

Why is it safe for people with ADHD take Adderall during his whole life, if it is for people without ADHD?

Is it because if you have ADHD, then your body can some chemical compounds and compouds Adderall provides the missing chemicals? So, if you do not have ADHD, Adderall, you are too many chemicals in the body?
