How dare a pharmaceutical company sell a product? How dare doctors decide to prescribe medicine? While that was slightly melodramatic, here is a quote from the article:
Schwarz has no doubt that A.D.H.D. is a valid clinical entity that causes real suffering and deserves real treatment, as he makes clear in the first two sentences of the book: “Attention deficit hyperactivity is real. Don’t let anyone tell you otherwise.” But he believes that those who are disabled by the condition deserve a wider range of treatment options than an endless litany of stimulants with chirpy names like Vyvanse and Concerta.
... Great, so it all boils down to the pharma companies not creating enough drugs for ADHD? But it's their fault that there are too many drugs? I am not particularly impressed, and to me it feels like the author is just manufacturing conflict for the sake of selling a book.
