Columbia, SC Drug Crimes Defense Lawyer

Trafficking Thresholds and Mandatory Minimums

Trafficking charges in South Carolina do not require proof of an intent to sell. Possession of a quantity above the statutory threshold — regardless of purpose — is trafficking under SC law. Under § 44-53-370(e), the thresholds and mandatory minimum sentences include:

• Marijuana: 10 lbs triggers trafficking; mandatory minimums begin at 1 year and escalate to 25 years at 10,000 lbs or more
• Cocaine: 10 grams triggers trafficking; 28–100 grams carries a mandatory 7-year minimum with no parole eligibility
• Methamphetamine: 10 grams triggers trafficking; mandatory minimums parallel cocaine thresholds
• Heroin: 4 grams triggers trafficking; 14+ grams carries a mandatory 7-year minimum

These are floor sentences, not guidelines. A judge cannot sentence below the mandatory minimum regardless of mitigating circumstances, which is why the charge itself — and whether the quantity meets the trafficking threshold — is the first thing to analyze in any serious drug case.

How Drug Cases Are Actually Built

Most drug cases don't begin with a traffic stop. The cases with the most serious exposure typically involve weeks or months of law enforcement investigation before a single arrest: controlled buys using confidential informants, wiretap applications, surveillance, and coordination between local law enforcement and federal agencies including the DEA and FBI.

Understanding how the 11th Circuit Solicitor's Office and federal prosecutors construct these cases — what evidence they prioritize, where the chain of custody is most likely to have gaps, and how informant credibility gets attacked at trial — is the analytical work that happens before any courtroom argument. As a former state prosecutor, Marion Moses has been on the other side of that preparation.

Specific defense angles that matter in South Carolina drug cases include:

• Search and seizure challenges under the Fourth Amendment and Article I, Section 10 of the South Carolina Constitution — whether the stop, search, or warrant was legally valid
• Chain of custody — how the substance was collected, stored, and tested, and whether lab procedures at SLED (the South Carolina Law Enforcement Division) meet evidentiary standards
• Informant reliability — South Carolina courts have addressed confidential informant credibility in cases including State v. Adolphe, and an informant's history, compensation, and prior reliability are all subject to discovery
• Quantity disputes — when the charged quantity sits near a mandatory minimum threshold, independent analysis of the weight and composition of the substance can directly affect the charge

When a State Case Becomes a Federal Case

This is a question most drug defense pages don't address directly. A case can begin as a state arrest and be picked up by federal prosecutors — a process called "adoption" — when the quantities, geographic scope, or defendants involved make federal prosecution strategically preferable for law enforcement.

Federal drug convictions carry mandatory minimums under 21 U.S.C. § 841(b) that are separate from South Carolina's thresholds and are typically served in federal prison without the parole eligibility that exists in some state cases.

Richland County and the 11th Circuit

Drug cases in Columbia are prosecuted through the 11th Circuit Solicitor's Office, with Richland County General Sessions Court handling felony-level charges. The Solicitor's Office has a dedicated drug prosecution unit, and cases involving significant quantities or repeat offenders are prioritized for trial rather than diverted. Knowing how that office makes charging and plea decisions — what they'll negotiate on and what they won't — is a product of years of practice in these courts, not general knowledge about the criminal justice system.

The firm also represents clients in Lexington County drug cases, where the same 11th Circuit prosecutorial framework applies in Lexington County General Sessions Court. For clients facing DUI charges alongside drug possession charges — a common combination — both matters can be handled together.
