You seem to be equating therapeutic doses of amphetamines with recreational doses (i.e. overdosing). The amount of amphetamines people take for recreational purposes or for those all-nighters and whatnot are more than what people take for medicinal purposes. So it's not some magical bright line that makes amphetamines good for some people and bad for others. But it is a condition that makes therapeutic doses benefici…
#1) Let's get specific about our dosages then. I know people prescribed 60mg of adderall a day. And lots of people prescribed 40mg. I guarantee if you give a person with no amphetamine tolerance 40 mg of adderall (yes, even if you split it into two doses) they are going to know they are on some speed. In fact, most people I know that use adderall "recreationally" (whether for pleasure or productivity -- that is they…
#2) I agree that ADHD is a complex subject and diagnosing is hard. However, given that something like 80% of people with ADHD show improvement with amphetamines, I'm not sure what the point is of this line of argument. Even if ADHD really is a cluster of similar issues, if they all can be treated the same way, then it doesn't really matter whether it's a single issue or multiple.
I'm not sure why you're trying to draw a comparison with depression. The only real connection here is that they're both psychiatric diagnoses, but beyond that they're not the same at all.
> But I doubt you can find me any study showing that we've ever seen so many people on high-dose daily amphetamines from a young age through adulthood until the past decade or so.
That's completely irrelevant. Why would you want a study looking at the number of people being prescribed? There's nothing you can conclude from the fact that more people are taking it now than before, because the number of people taking it has no relevance to its long-term effects. All that really matters is whether a statistically significant number of people have been taking it, and that's certainly been true.
