Not sure which one(s) though There's only one "amphetamines". There is a specific molecule (and its enantiomer) called " amphetamine". There are some other amphetamine-class drugs like methamphetamine (crystal meth) and MDMA (ecstasy). Methylphenidate (Ritalin) isn't even an amphetamine-class drug.
