Regarding the universal efficacy of stimulants, it should be noted that stimulants helping with something is not diagnostic of a medical issue. Stimulants help everybody with with getting-work-done issues. That's why the majority of Americans take stimulants daily, and many workplaces give them away for free.

So sure, if someone is having trouble keeping up with the pace of their societally assigned hamster wheel and find stimulants help, sure, they should go for it. But they should not mistake that for an illness, any more than a person needing a step-stool to get to the top cupboard should think they have some sort of growth hormone deficiency. Artificial environments can require artificial compensation, but that doesn't mean there's some sort of medical problem.
