The history of amphetamine is a very interesting read. "support funding" was by Shire Pharmaceuticals, who developed and previously manufactured Adderall, so read critically.

IMHO, it's interesting because of the trends of drug use and abuse. Doing a deep dive into ADHD meds because I was recently prescribed Adderall but I can't get any locally due severe shortages the supply is only for existing customers only.
