HNB Device
"Non-burning, nicotine for users, low tar content. As the heating temperature (below 500â„ƒ) is lower than the combustion temperature of traditional cigarettes (600-900â„ƒ), the harmful components produced by tobacco high-temperature combustion pyrolysis and thermal synthesis are reduced, and the release amount of side-flow smoke and environmental smoke (second-hand smoke) is also greatly reduced."

Heating non - combustion products are electronic devices containing tobacco. When you heat them, they produce a nicotine-containing vapor that you can inhale.

They are different from traditional cigarettes and work by heating tobacco to a very low temperature. Tobacco is heated to 350 Â° C in a heat-incombustible device, while traditional cigarettes burn at up to 900 Â° C.

Still, the temperature at which non-combustion products are heated is high enough to vaporize and inhale harmful chemicals.

Although both are electronic devices, heated non-combustible products are also different from e-cigarettes or steam devices. These usually use chemical liquids and do not necessarily contain nicotine. E-cigarettes tend to heat liquids to around 250 degrees Celsius to produce vapor.
