The rules aren't strict enough IMO but the observed variation is very low in practice. Australia allows very similar amounts of wriggle room in theory [1]. Most people I know in Australia with ADHD are treated with generics (very common among my friend group for some reason) and none that I am aware of have noticed any substantial differences between generics and brand name equivalents but I couldn't quickly find any studies that have investigated this. I wonder if that is due to variation in balance of the included amphetamines (as most of these are multiple active ingredients) though as I doubt that the inactive ingredients would play a significant part.
