With only three firms dominating the market, reliance on self‑declaration without effective audits has created incentives for under‑reporting and fueled illicit trade. This SPDC brief highlights the scale of under‑reporting and calls for stronger monitoring and enforcement to safeguard fiscal and public health objectives.
