Does anyone know if there are any published stats / estimations about the prevalence of amphetamine prescriptions in the United States. I have this gut feeling it's pretty high, at least in the tech industry. I don't believe this is problematic but it feels like a taboo topic. If use is common we should be better about talking openly about it.
