The drug trial of embattled dancehall entertainer Vybz Kartel is to begin in the Corporate Area Resident Magistrate's Court today.
Kartel is facing the charge of illegal possession of marijuana.
The police said they held Kartel, whose real name is Adidja Palmer, and others in a hotel room in New Kingston last September.
The police said a quantity of ganja was found in the room.
Kartel is also before the courts on other charges including murder and conspiracy to pervert the course of justice.
