On April 14, Iowa Attorney General (AG) Brenna Bird, leading a coalition of 13 state AGs, sent a pointed letter to Visa, Mastercard, American Express, and Discover. Their message was clear: payment networks are expected to help shut down the U.S. market for unauthorized e‑cigarette products.

For financial services institutions that support e-cigarette merchants — card networks, sponsor banks, acquirers, independent sales organizations (ISOs), payment service providers (PSPs), and platforms — this letter is the latest signal of increased regulatory and enforcement risk for financial services companies that provide services to sellers of unauthorized e-cigarette products.
