It seems to me Adderall is not even marketed in Europe. Can't find anything suggesting otherwise, but it's hard to find a source on something never happening.

Though I can tell you definitely at least that here in Norway, Adderall is not an approved drug(neither is dexedrine). The only approved amphetamine here is Vyvanse and its generic form Aduvanz.

I did some digging and apparently no amphetamine based drugs had been approved for ADHD in Europe back in 2011.(1) Back then the only ADHD med was methylphenidate (ritalin, concerta). This must have changed somewhere between 2012-2014 when dextroamphetamine(attentin) and lisdexamfetamine(elvanse) got approved for ADHD treatment as well. So today in majority of EU countries (possibly in all) it is possible to get 100% dextroamphetamine based ADHD medication. As far as I can tell it seems like levoamphetamine is not approved for medical use at all so that's why adderall isn't prescribed here.
