Think what this means though. You fit a criteria. Then ask why do we use this criteria? Trace the history of this criteria through the DSM. The criteria is arbitrary. There is no basis for it.

The field of ADHD began when stimulants were shown to help make kids calmer. And since then it has been a matter of: how to find other people that this medicine (that no one else is allowed and is highly controlled) will help.

There was never an investigation into maybe it is caused by environment/society.

The unquestionable commonality of ADHD is an impairment that impacts the ability to live/work.

No one starts here, and then looks at the potential causes. They see if you fit the criteria, and if you do then you medicate.

Medication is premised on it being a neurodevelopment disorder from birth, hence why ADHD people can take stimulants and no one else can. But this is not proven in any way.

My biggest gripe is that every ADHD person will tell you its okay for only them to take stimulants because their brain is different for normal people and hence they are immune to the negative side-effects. Which is not proven. The risks are under-stated, and the investigation of the true cause is cut short for convenience and revenue.
