Heated tobacco products (HTPs) are commercially available in a growing number of countries worldwide. Their availability depends on national regulatory frameworks, with some countries permitting their sale under specific product regulations, while others regulate them under existing tobacco legislation or prohibit them altogether.

HTPs heat processed tobacco instead of burning it, producing an aerosol that contains nicotine but no combustion smoke. As a result, regulatory approaches to the marketing of HTPs vary considerably between countries.

Currently, 57 countries market heated tobacco products.
