Jadakiss has been indicted on drugs and weapons charges.
Jadakiss, real name Jason Phillips, was arrested last October after the police searched the car he was in.
Answering to the charges in court, he pleaded not guilty, saying he was in the back of the car and had no idea there was a gun up front.
If he is found guilty and convicted, he could go down for a period of 16 months to 7 years.
