Yea, the Adderall knows when you're taking it for studying and when you're taking it recreationally. So when you take it for studying, the Adderall says OK, he's being a good boy so we're not gonna hurt him. But when you abuse it, however, the pills say Holy shit he's abusing us, let's fuck him up! So to answer your question, yes! The pills are either bad for you or not depending on your intentions when taking them. If you're a really smart guy you might can find a way to trick the Adderall, like maybe opening a book so they'll think you're studying, but then doing something else after you swallow them.
