Never been diagnosed with adhd but when using adderall to study, it gave me focus and the mental energy i needed to get all hw done. wonder drug. why?

It's what it does: Adderall can improve focus in almost anyone. Benefit from its use does not make you ADD. As a mixed salt of methamphetamine it was used in that manner by truck drivers for years before it became a listed Schedule 2 prohibited drug. Use it at your own risk, the feds equate use without a valid prescription as if it were cocaine.
