Pretty much yes, adderall is the most "similar" to typical euro speed (mixed enantiomers of L- and D-amphetamine). Obviously illicit manufacturers do not bother making 5 different salts like in adderall, but adderall does contain 23% of Levo-amphetamine (something most people detest and that's why Dexedrine is preferable, although some enjoy the PNS stimulation of Adderall), not me....made me feel like I was having a heart attack all day, while this never happens with Dexies.
