Watching Other Cities Can Help Southwest Virginia

Southwest Virginia is connected to the rest of the country by major highways like I-81 and I-77. These roads don’t just move people around, but they also play a role in how illegal substances move from larger cities into our smaller towns and rural areas. Because of this, changes in the drug supply that start in big cities often reach Appalachian communities later.

Cities like Baltimore and Philadelphia are important for us to watch. They are large drug markets where new substances and new combinations often first appear (Sisco & Appley, 2023; Hochstatter et al., 2025). Over time, these changes can spread to West Virginia, Southwest Virginia, and other rural Appalachian areas. This pattern has been seen before, including when fentanyl replaced heroin and when new substances began to be mixed into fentanyl (Centers for Disease Control and Prevention, 2023).

Baltimore is a key early warning city for Southwest Virginia. Law enforcement investigations show illicit substance supply connections between Baltimore and Appalachian states, including West Virginia, which shares transportation routes with Southwest Virginia (U.S. Department of Justice, 2023). Baltimore has also been one of the first cities to identify new and dangerous substances mixed into street drugs, thanks to detailed medical examiner reports and drug testing programs (Sisco & Appley, 2023).

Philadelphia also plays an important role. The city closely monitors and researches its drug supply, allowing public health experts to quickly spot changes in what drugs contain. Studies from Philadelphia have helped identify new drug additives and shifts in fentanyl products before those changes appeared in other areas (Park et al., 2024).

By paying attention to drug trends in Baltimore and Philadelphia, we could possibly gain insight into what is coming next. This early warning helps emergency responders, health care providers, and community organizations prepare by adjusting overdose prevention efforts, strengthening training, and sharing information with the community. In the ever-changing substance environment, knowing what may be coming next can help save lives.
