No. Adderall is normally prescribed in the XR formulation (meaning it's an extended/slow release capsule), and has amphetamine as the active ingredient. Methamphetamine is a different molecule altogether, and typically it's not packaged in slow-release capsules. Yes, methamphetamine is structurally related to amphetamine, but you shouldn't make the mistake to think they are interchangeable. Very often the difference…
Adderally XR formulations are still a minority of prescriptions. Talking about methamphetamine as a different molecule is not helpful, as Adderall itself is not a single molecule. Which I suspect you know, as you mention different enantiomers of thalidomide. However you don't point out that adderall itself is a 3:1 racemic mixture of l and d amphetamine. The real discussion here is the receptor binding affinity of th…
The vast majority of adderall prescriptions are XR.
Enantiomers are structurally “the same molecule” (or people often speak this way depending on the context) but with different optical configurations.
