What Are HEETs?
HEETs refer to heat-not-burn tobacco sticks used in electronic cigarette systems, such as those from IQOS. They contain processed tobacco designed to be heated, not burned, releasing nicotine vapor.
Key Components of HEETs
- Tobacco substrate: Ground tobacco leaf treated for controlled heating.
- Filter: Multiple layers to cool vapor and improve draw.
- Outer wrapper: Biodegradable material enclosing the stick.
How HEETs Work
A specialized device heats the HEET to temperatures between 250-350°C, avoiding combustion. This extracts nicotine and flavors while reducing harmful byproducts like tar and carbon monoxide.

Benefits and Risks
- Reduced exposure: Lower levels of carcinogens versus traditional cigarettes.
- Disadvantages: Potential health risks remain; not harm-free.
Safety and Regulations
Regulatory bodies classify HEETs as tobacco products. Adhere to age restrictions and use guidelines to minimize risks. Ongoing research evaluates long-term effects.
