"I'm not advocating using drugs to help you think better, btw, but there's more of a case there than in sports."
This could mean several things. i'm curious what you think about a few cases that make explicit some of the ambiguities.
1 A person has debilitating OCD and is prescribed ritalin by a psychiatrist, which they take daily, so they can function.
2 A healthy person at the top of their field takes ritalin and other stimulaties daily over his career to enhance performance, prescribed by a physician. Cannot perform at the top of his field without it.
3 A person has debilitating OCD, is uninsured, and self medicates by taking illicitly obtained psilocybin mushrooms 6 times a year. (studies show that psilocybin reduces symptoms of OCD for longer then a month).
4 A person has treatment resistant cluster headaches that stops them from thinking. Their treatment provider informs them that their best bet is probably psychedelic mushrooms, which must be obtained illicitly.
5 A person has a psycho-spiritual crisis after finding out their religious leader is a fraud, and takes illicit LSD in the aftermath with confused and possibly self destructive intentions. Partly as a result of this experience, their psychology is permanently altered in a way that makes their thinking better.
6 An alcoholic uses illicitly obtained LSD to induce the kind of spiritual experience his psychologist said correlated with a relapse of alcoholism.
7 A musician takes illicit drugs as part of the creative process.
8 A musician takes prescribed drugs not according to directions as part of the creative process.
