I think (I could be wrong) that lawfags point was that sentencing guidelines mean that the judge will only sentence based on the highest charge that was convicted and run the lesser sentences as concurrent so they don't actually do extra time for them. Like when a tweaker breaks into a car and they charge him with drug possession and burglary. He gets sentenced on the burglary charge and the possession charge is sentences within the same time as the burglary charge. So 3 years for burglary and 1 year for possession, but the one year runs at the same start date so he only does 3 years. On that same note, a small minority in prison are actually locked up for drug charges, but they have drug charges on their record, so it looks like a bunch of people are serving time for drug charges, but those drug charges are rarely the primary sentencing offense.
