You need to hire a lawyer to fight the illegal search. File a motion to suppress and put the officer on the stand and examine him on the two reports. If the search is found to be a violation of your 4th Amendment, then the fruits of the search (controlled substance, etc.) will be suppressed and cannot be used against you. The state's attorney most likely will dismiss the charges.
