HEETS, aka HeatSticks, are specially produced tobacco products that contain tobacco material along with several other filter sections. Heets tobacco is intended exclusively for use with a precisely controlled heating device, which heats rather than burns the tobacco.
A heated tobacco product (HTP) heats up tobacco using a battery-powered heating system. While heating, it generates an aerosol that contains nicotine and other chemicals, that is inhaled. It also generates smoke. The emissions contain gases, liquid and solid particles, and tar.
