Historically interesting. Forty years back you could get stuff basically like amphetamines at truck stops. Then they got hard to get cause some converts to meth. Chemically between Adderall and meth is not that different. Closer to meth, more of that good stimulant feel. From a pure chemistry angle wild. Odd to think how much Adderall gets given to kids. Sure studies hard on that, not judging those who truly need it. But maybe eighty percent of folks in grad school were snorting it during tests.
