Adderall is regular (non-methylated) amphetamine, specifically a mixture of levo-amphetamine and dextro-amphetamine. There are minor differences in effect profile between methamphetamine and amphetamine, the biggest of these minor differences being in neuroprotectivity (it’s been a while since I’ve done the research but iirc amphetamine is mildly neuroprotective while meth is neutral or mildly negative, due to meth interrupting some metabolizing process). The major difference is that milligram-for-milligram, meth is 2-5x more potent than regular amphetamine.
The perception that they are very different is valid, though, because amphetamine is usually consumed therapeutically (lower doses, guaranteed purity, controlled dosing schedule, safer administration route) while meth is usually consumed recreationally (higher doses, unknown and often dubious purity, erratic dosing schedule, riskier administration routes). Injecting a quarter of a gram of street meth over a three day binge is much more harmful than taking 40mg Adderall extended release formulation by mouth every morning.
