How did Sam and Caroline get into taking high doses of ADHD medication? We think it was via Scott Alexander Siskind, the psychiatrist behind the rationalist blog Slate Star Codex.
Siskind occasionally writes up particular psychiatric drugs as public education. One popular piece was “Adderall Risks: Much More Than You Wanted To Know” from December 28, 2017.
Not to cast further aspersions or anything, but siskind did write a sort of follow up (titled psychopharmacology of ftx or something like that if you feel like googling it) where he explicitly denies ever having met the FTX psychiatrist/dealer, even though a) he admits they actually worked in the same hospital for a time and, perhaps more tellingly, b) no one asked.
Also according to the birdsite the ftx psychiatrist may have in fact been a huge creep.
