Cannabis in Charleston SC — Lowcountry, Port City, Tourism

Charleston (city pop. ~155,000; metro ~850,000) sits at the heart of the Lowcountry. Economy dominated by tourism (~7M visitors annually), the Port of Charleston, Boeing 787 assembly in North Charleston, Joint Base Charleston, and MUSC. Mayor William S. Cogswell Jr. (R), first Republican mayor since 1877. ACLU SC reported CPD arrested Black residents for marijuana at 9.4× white rate. Cannabis policy not a city-level priority.

Charleston — The Lowcountry Hub

Charleston is the cultural and economic heart of South Carolina’s Lowcountry — the coastal region centered on the city, Berkeley County, Dorchester County, and surrounding sea-island communities. The city itself has a population of approximately 155,000, but the metro area approaches 850,000 residents. Charleston combines historical preservation (the Historic District is one of the most photographed urban environments in the U.S.), tourist economy, military-installation density, and modern industrial base.

Mayor William S. Cogswell Jr. (R)

Cogswell took office in January 2024 as the first Republican Charleston mayor since 1877. His policy priorities have centered on flooding/drainage infrastructure, affordable housing, tourism management, and historic preservation — not cannabis policy. Charleston has not pursued city-level decriminalization or declination policy for cannabis.

The 9.4× ACLU Arrest-Disparity Finding

Per the ACLU of South Carolina’s racial-disparity analysis, Charleston Police Department arrested Black residents for marijuana possession at 9.4× the rate of white residents. The disparity is among the highest in SC. Charleston County overall has documented racial disparities in cannabis enforcement consistent with statewide patterns.

Cross-Border Reality from Charleston

Virginia adult-use: ~7.5 hours via I-95 to Richmond / DC area.
EBCI Cherokee NC: ~5 hours via I-26 / I-40.
Georgia low-THC: ~2 hours via I-95 to Savannah, ~5 hours to Atlanta.

Port of Charleston Federal Interdiction

The Port of Charleston handles substantial container and bulk-cargo traffic; cannabis-trafficking interdiction at the port is coordinated by U.S. Customs and Border Protection (CBP), DEA Atlanta Field Division, and SLED. International maritime cannabis-shipment cases routed through Charleston produce substantial federal-prosecution caseload. See port + airport interdiction page.

Charleston International Airport

Charleston International Airport (CHS) at Joint Base Charleston handles ~5+ million passengers annually. TSA-administered passenger screening at CHS does not target cannabis specifically (TSA’s focus is aviation security), but federal cannabis possession at the airport remains illegal. Out-of-state travelers carrying cannabis from legal-rec states should be aware of federal jurisdiction at airports.
