Even if you could, I wouldn't recommend it. Two different doctors have mentioned that the generic for Adderall has caused problems for patients so they always recommend the brand name. And no, it isn't a big pharm conspiracy. This is similar problem to what happened with some of the generics for wellbutrin that eventually got pulled from the shelves by the FDA. Anyway, I would imagine the risk that you might end up with a substandard product would be a too high.
