Major West Virginia Employers — Cannabis Stance Across the Mountain State Economy

Last verified: May 2026

WVU and WVU Medicine — Morgantown

West Virginia University and the affiliated WVU Medicine system — anchored by J.W. Ruby Memorial Hospital (1 Medical Center Drive, Morgantown) — together constitute the largest employer in the Mountain State. The university, the WVU Health System, and the affiliated 24-hospital network employ tens of thousands across academic, clinical, research, and administrative roles. Clinical employees fall under the drug-free workplace policy reinforced by Joint Commission accreditation, WV Board of Medicine and Board of Nursing licensure exposure, and federal CMS conditions of participation. Non-clinical academic employees fall under the university’s drug-and-alcohol policy. See Morgantown / WVU page; see healthcare boards.

Toyota Motor Manufacturing West Virginia — Buffalo, Putnam County

Toyota Motor Manufacturing West Virginia (TMMWV) operates at One Toyota Way, Buffalo (Putnam County), employing approximately 1,800 workers producing engines, transmissions, and hybrid components for North American Toyota assembly plants. The plant has been a Putnam County economic anchor since 1996. TMMWV maintains a corporate drug-free workplace policy reflecting Toyota’s North American manufacturing standards; pre-employment, post-accident, and reasonable-suspicion testing apply, and a positive cannabis test disqualifies a candidate or terminates an employee regardless of West Virginia patient status.

Marshall University — Huntington

Marshall University (1 John Marshall Drive, Huntington) and its affiliated Marshall Health network and Joan C. Edwards School of Medicine constitute the largest employer in Cabell County. Faculty, clinical staff, and athletics personnel fall under the university’s drug-and-alcohol policy and (for clinical roles) the Marshall Health drug-free workplace overlay. See Huntington / Marshall page.

CSX Transportation — FRA Part 219 Rail

CSX Transportation, the rail operating subsidiary of CSX Corporation (Jacksonville, FL), is one of the largest single employers of train and engine service crews and Maintenance-of-Way workers in the Mountain State. CSX track in West Virginia spans the Mountain Subdivision, the New River Subdivision, the Kanawha Subdivision, and connections in Huntington, Hinton, Grafton, Keyser, and Cumberland-adjacent points. All train, engine, signal, and dispatch service employees are subject to Federal Railroad Administration 49 CFR Part 219 drug-and-alcohol testing. State-program cannabis use is no defense, and Schedule III rescheduling does not change the analysis. See CDL / DOT / FMCSA page.

Procter & Gamble — Tabler Station, Berkeley County

Procter & Gamble’s Tabler Station campus on the Berkeley County / Inwood line is one of the largest manufacturing and distribution sites P&G operates in the United States, producing and warehousing personal-care and home-care brands for the East Coast. The Eastern Panhandle plant employs over 1,800 workers. P&G maintains a drug-free workplace policy across its U.S. operations; pre-employment screening is universal; positive cannabis screens disqualify regardless of West Virginia or neighboring Maryland (Berkeley County is two miles from the MD line) patient status. See Eastern Panhandle page.

Mylan / Viatris — Morgantown

The Viatris Morgantown manufacturing campus (formerly Mylan Pharmaceuticals, 781 Chestnut Ridge Road) is one of the largest generic-pharmaceutical manufacturing sites in the United States. As a U.S. Food and Drug Administration-regulated pharmaceutical manufacturing facility, the campus operates under stringent good-manufacturing-practice and security controls, including drug-free workplace requirements applied to manufacturing, quality, and warehouse operators. The April 28, 2026 federal Schedule III rescheduling does not modify the FDA-regulated pharmaceutical-manufacturing posture.

Chemical Valley — Charleston / Kanawha Valley

The Kanawha Valley around Charleston is West Virginia’s historic Chemical Valley, with significant operations of Dow Chemical, Chemours (the DuPont specialty-chemicals successor), Covestro (Bayer MaterialScience successor, polyurethane and polycarbonate at Institute and South Charleston), Bayer CropScience legacy operations, and other chemical-industry employers. The Chemical Valley facilities are subject to OSHA Process Safety Management (29 CFR 1910.119) and EPA Risk Management Plan (40 CFR Part 68) requirements that compound the operator-level drug-free workplace posture. Pre-employment and random testing are standard. See Charleston city page.

Antero Resources & EQT — Marcellus Natural Gas

The Marcellus Shale natural-gas operations across the Northern and North-Central West Virginia counties (Doddridge, Harrison, Marshall, Ohio, Tyler, Wetzel, and surrounding) employ thousands of well-pad workers, midstream-pipeline crews, and field service workers under Antero Resources, EQT Corporation, Southwestern Energy, and field-service contractors including Halliburton, Schlumberger (now SLB), and Liberty Energy. The U.S. Department of Transportation Pipeline and Hazardous Materials Safety Administration (PHMSA) drug-and-alcohol regulations at 49 CFR Part 199 apply to interstate-pipeline-operations workers; oilfield service contractors typically apply FMCSA Part 382 to CDL drivers and company drug-free workplace policies to the rest. State-program cannabis use is no defense in any of these segments.

AT&T Data Centers — Eastern Panhandle

The federal-government data-center cluster in Berkeley and Jefferson Counties — including AT&T, Equinix, and federal-tenant data-center operations — depends on cleared workforce subject to the federal Drug-Free Workplace Act of 1988 framework and contract-specific drug-testing requirements. See clearance carve-out.

Healthcare Systems — CAMC, Mon Health, Cabell Huntington

Charleston Area Medical Center (CAMC) (501 Morris Street, Charleston) is the largest hospital by bed count in the Mountain State and one of the largest employers in Kanawha County. Mon Health Medical Center in Morgantown competes with WVU Medicine for the North-Central regional patient base. Cabell Huntington Hospital serves the Tri-State Cabell-Wayne-Boyd corridor and is the affiliate hospital of Marshall Health. All three systems maintain drug-free workplace policies and Joint Commission accreditation. See healthcare boards page.

Federal Civilian Footprint — The 30,000-Job Bracket

FBI CJIS Clarksburg, NIOSH Morgantown, four VA Medical Centers, three Federal Bureau of Prisons facilities, the West Virginia Army and Air National Guard, the Robert C. Byrd United States Courthouse in Charleston, and federal-contractor workforce add roughly 30,000 federal civilian and military jobs in the Mountain State for which cannabis use is categorically incompatible regardless of state law. See FBI CJIS / clearances.

The Mountain State Economy Reality

• The largest single Mountain State employer (WVU + WVU Medicine) maintains drug-free workplace policy across academic and clinical roles.
