Great, that picture is much clearer! So it looks like your real peaks are ~ 2897, 1559, 1488, 1474, and 1225. Too bad those peaks at 24/2600 aren't real, those would very telling.
So if you know its a drug that makes things a little easier(ish). This is for an undergrad forensics chemistry course I assume? What compound classes have you covered so far in the course?
Its most likely an OTC drug like aspirin/caffine ect as I doubt they would spend a lot of money for a lab assignment and they won't give you anything dangerous in case of accidental exposure.
The majority of commercial drugs have aromatic groups so you can make a good bet that one or both peaks in that region are from benzyl or similar. The majority also have at least one heteroatom. There are no OH/NH2 peaks which tells you something important as well.
With these facts in mind, look over a good IR table again and see if you can come up with some theories about what all is present on your molecule. Post what you come up with and we can go from there.
