In South Carolina, drug trafficking charges are typically dependent on how much of a drug you have in your possession.
Drug trafficking itself refers to the cultivation, manufacturing, distribution and sale of drugs and illicit substances. In South Carolina, none of these necessarily have to be proven in order to be charged with drug trafficking. Drug trafficking charges are applied when you have a large amount of a drug, with the implication that if you are engaging in trafficking if you have so much in your possession. The exact amount that you need to have on you depends on the drug in question – the threshold is 10 pounds for marijuana, but only 10 grams for cocaine or methamphetamine.
