I have read that there is no real hard data that ADHD drugs actually improve your GPA or things like that long-term. I've read that the meds make it easier to focus on boring repetitive tasks but make it harder to do original, creative thought.
I have also read that for most kids/adults, you may have to keep taking higher and higher doses for it to keep working. There can be alot of side effects too- it can shrink your amygdala, an important part of the brain. It can affect your growth rate and make children shorter than they should be. It can cause weight gain and provoke diabetes. It can provoke manic depression in susceptible kids.
It can give you bigger problems than you started with. We don't use any meds but as a doctor, I've read about it.
