No, the West Virginia Medical Cannabis Act prohibits medical cannabis patients from cultivating marijuana at home for personal use. The only way you can access medicinal cannabis legally is to purchase from state-licensed medical marijuana dispensaries.
However, legislation (House Bill 2550) is currently pending to permit cannabis patients and caregivers to cultivate up to 10 marijuana plants (at most five mature plants) legally in their residences for therapeutic use. Only cannabis growers licensed by the West Virginia Bureau of Public Health can cultivate marijuana in the state at approved locations. In 2020, the Bureau of Public Health announced 10 successful applications for medical marijuana grower permits.
