In which region is methamphetamine most likely to be used?

• A. Mid-Atlantic region of NJ, NY, DE, MD, DC, and PA
• B. New England states
• C. The South
• D. The West Coast states of CA, OR, and WA

Answer: (D)

Regional patterns in methamphetamine use are driven by where production and distribution networks are strongest, plus local demand and access. The West Coast has historically shown higher meth use because production and trafficking were concentrated there, especially in California and nearby states, which made meth more readily available and affordable. In the 1990s and early 2000s, meth labs and a robust supply chain were more common on the West Coast, contributing to higher use compared with the Mid-Atlantic, New England, or the South. While regulatory changes and shifting supply chains later affected patterns, the West Coast nonetheless has long been associated with greater meth use, making it the region most likely to be used.
