Major David Kelly confirmed the charges, stating that although there were other people inside the dwelling on only Jones and Thornton received citations.
"In this particular case other people were in that apartment but only two were charged," said Kelly.
He pointed out that under constructive possession others could be charged but that wasn't the case.
Major Kelly wouldn't confirm or deny any other potential charges against Thornton.
"I can't comment on that other investigation," he said.
Thornton played in 11 games this season for the Wolfpack, leading them in rushing (768 yards) and touchdowns (4).
Jones, a redshirt freshman, is a reserve safety for the Wolfpack.
A school official confirmed today that Wolfpack head coach Dave Doeren is aware of the marijuana charges but is still gathering details regarding the situation.
Update from NC State media relations:
The NC State Athletics Department takes any allegation of illegal activity very seriously.
We have university and athletic policies and procedures in place regarding our expectations of conduct for our students.
Coach Doeren has suspended Shadrach Thornton indefinitely and J.J. Jones earlier had informed the coaching staff that he plans to transfer from NC State.
We will await the outcome of the legal process before we comment further.
