If you don't see the difference between metaamphetamines and their deriatives vs methylphenidate, then you don't have any right to comment on the subject. And no, it's not a "drug". Calling it such is guilt-tripping those that want to/do use MPH it and there's already a ton of that in the lives of people with ADHD. A parent hearing somebody call MPH a "drug" = "There's no way in hell I'm giving my kid DRUGS!!11". For kids with ADHD (and for people with ADHD in general), medication is massive a life changer ( and saver too ) - from often nightmare to livable/decent. You don't have any right to take that away from them.
If parents (or anyone else) is unable to overcome their cognitive dissonance from drugs being called drugs, they really have no business making decisions about their use.
Where do you buy your paracetamol? Surely at the drugstore.
