>>2226217I'm not sure if this applies to adderal but drugs may have their effects lengthened through either making their tablet form slower to digest, or by using a compound that is extremely similar in structure and physiological effect, but itself takes longer to be metabolized by the body. In pic related, pentobarbital and phenobarbital have virtually identical effects but phenobarbital has a half life ~2-3 longer than pentobarbital because of a different single attached group.
If the poster you are replying to is referring to some isomer of the amphetamines found in adderall the effects described could very well be legit.
