> Whereas adderall is not technically addictive

I don't think I've ever heard someone claim that Adderall isn't addictive.

> use of amphetamines and stimulants such as Adderall can result in tolerance and physiological dependence and can lead to the development of a substance use disorder. Misuse of prescription stimulants such as Adderall for any reason (e.g., to improve academic performance, reduce the effects of other drugs, etc.) is associated with both substance use disorders and use of other substances.
