I'm talking as someone who was denied medical treatment for 7 years because the first specialist I saw assumed, based on my age, that I was trying to scam them for a prescription.
Those years were basically lost, and that wouldn't have happened if there wasn't so many people seeking phony diagnoses.
People abusing ADHD medication like that is the reason that the medication is so tightly controlled and hard to get as someone who actually has ADHD though.
It stops being "Their body, their choice." when tangible harm is being caused to people who actually need the medication to treat a neurodevelopmental disorder.
