To the girl worried about her 1,000 pills of a non-controlled substance: I don't think you'd have as much to worry about. The reason I say this is just because they are looking to keep controlled substances out of the country so that's probably what they are focusing on. However being that it might be a larger package with all those pills rattling around, which might cause closer inspection. At the end of the day you could technically still get in trouble for buying prescription medication without a prescription whether it was a controlled sub. or not.
