Did I tell you I used to abuse adderall at 15 yrs old?
Were you doing it to get high?
No, for concentration for online games. I was diagnosed with ADD
If the adderal was prescribed or your ADD, then there's nothing wrong with taking it.  If you needed it to help you concentrate, then you're taking it for precisely the reason it was probably prescribed in the first place.
I didn't like the idea of being dependent on a drug.
If it helped you get through school it could be OK, but you're right to be concerned about long term usage. It's good you were able to get off of it and still thrive.
