They added back his good time credits. A violation for tobacco is not an offense that can add to a sentence. MOst inmates start their bid with a 15% good time credit, giving them an "out date" of 85% of their original sentence. They can only lose that time, not have more added unless they catch another felony charge like drugs, a weapon, an assault or worse - not for tobacco.
