>Adderall may have neurotoxic effects in doses higher than the recommended therapeutic dose; however, it may also potentially be neurotoxic in prolonged regular doses over a long period of time.

There is a lot of recent research on this and it does not agree with you.

I'd say it does agree with OP considering the article used "may" and is followed up by "Currently, there is not enough scientific evidence to support Adderall’s neurotoxicity. Additional research on the effects of prolonged stimulant use is necessary.

I believe OP was saying that neurotoxicity has only been definitively shown in higher doses. Granted I highly doubt no studies show neurotoxicity at lower doses, but it doesn't look to be a settled matter.
