Hairston was arrested last month during a license checkpoint while driving a rented 2013 GMC Yukon. The UNC junior guard and his passengers, Miykael Faulcon and Carlos Sanford, were all charged with misdemeanor marijuana possession.
Hairston was also charged with driving without a license.
Those charges were dismissed on July 19. According to court records, Hairston obtained and completed a drug assessment and the state decided not to proceed based on those actions.
Hairston was also able to provide his current driver's license.
According to the June 5 incident report, police seized a 9mm handgun, a magazine with nine rounds of ammunition and a plastic bag containing 41.1 grams of marijuana that were found outside of the car. On July 10, Durham Police Department spokesperson Kammie Michael said the department did not anticipate filing any additional charges in the case.
The rental car has moved to the forefront regarding Hairston's eligibility for the 2013-14 season. USA Today first reported that the Yukon was rented in the name of Haydn "Fats" Thomas of Durham. That vehicle was rented from June 2 to June 5 for a cost of $1,261.64.
According to the paper, Hairston was also cited for speeding in Durham on May 13 in a 2012 Chevrolet Camaro. That car was rented under the name of Catinia Farrington with the same home address as Thomas.
Hairston has an Aug. 2 court date for that traffic violation.
Last Monday, UNC head coach Roy Williams issued a statement regarding Hairston's situation.
"PJ and I have had several discussions already and he knows he has made serious mistakes and there will be serious consequences as a result," Williams said. "Certainly the idea of suspending PJ has been discussed. However, he is not currently enrolled in summer school, is not practicing with the team and we have no games until November. There are several options available in terms of discipline but we are going to wait until the process is complete to decide on those options."
