Possession of certain types of pills can get you some time, believe me, I was a deputy for three years.. It's much more serious than pot, again depending on the substance. But without any priors and only having two it will be considered just possession without intent to resell most likely. If they were oxy's or such like it could be serious for him. I'm not familiar with sc law but tn has some stiff penalties the higher up the pill chain you go. Serious meaning if he does not cooperate ( snitch) then he could get a little more than probation. Like a nice fine, 30 days, and 3 years probation... Likely outcome is charges dropped with 1 year probation on good behavior, or dropped altogether depending on the legality of the stop
