My ex was charged with possession of cocaine but can help explain why and what these abbreviations stand for?

They found a crack pipe in his hotel room in Georgia. He was charged with PSS/Sel/Pur/MA VGCSA. What does all that stand for? He was charged with a felony but it was just a pipe with residue of cocaine. Why wasn't he just charged with paraphenalia? The paperwork says something about the "Georgia Controlled Substances Act". He also was charged with obstruction because he tried to reach for something twice on his bed (he did NOT have any weapons) after being told to remain still. He was subsequently thrown to the ground and suffered a concussion. His prior record was a DUI one year ago and check forgery 13 years ago and that's it. He also isn't from Georgia and was travelling. He lives in New York. What kind of time could he be facing? Could he possibly just be ordered to do some sort of drug treatment program, community service, and work with probation in his own state? THANKS for any help. He is basically a decent guy and he's been clean for a long time but just relapsed. We are still good friends and I'm worried for him.
