Yeah but it has the “amphetamine” part that gives meth it’s kick. And that’s what most people think of when it comes to the drug - the effect it has on a standard person, not the chemical name (otherwise they’d be calling methylprednisolone “meth” too. And let’s face it, the majority of the population doesn’t know why it’s nicknamed meth either).

On a legal scale, “amphetamines” are what’s regulated, not methyl groups.
