Criminals already aren't in their right mind.
South Carolina is a very difficult state to score drugs. Enforcement is a top priority for the SLED forces. Good old boys sitting on the porch drinking beer and smoking weed out in the country end up serving three to five on weed charges.
A lot of drug trafficking comes down from Chicago, up from Atlanta, and from Memphis.
South Carolina don't play around. Users have few local purchase points so a lot of them go on road trips to buy inventory for personal use.
