I'm not trying to be a dick but what evidence do you have for that? The people above broke down total numbers and drug offenses were literally top if not second place. I'd say that's still pretty 'full of drug pffenses' to me. And considering there are hundreds of arrests for drug users for every single arrest for a 'dealer', it's fair to say prisons are at least overly filled with low level drug offenses for what is necessary. People who use drugs do not benefit from jail and they harm no one (given they didn't break any other crimes).
