It only took 2 Chainz 2 minutes in court to do his business ... pleading not guilty to FELONY drug possession.
TMZ broke the story ... 2 Chainz was busted last June at LAX after TSA officers allegedly found codeine in one of his checked bags. Codeine is one of the main ingredient in sizzurp.
He was hit with the felony charge last week and appeared briefly in an L.A. courtroom today for his arraignment.
2 Chainz faces up to 3 years in prison if convicted.
