IQOS Heets are tobacco sticks that use a nicotine-infused liquid instead of traditional cigarettes. The stick is heated until it vaporizes and emits an aromatic smoke that users inhale. WHO has approved IQOS as a less harmful alternative to regular cigarettes, and it is also cheaper than tobacco products. This newly designed smoking substitute is tar-free, giving users a range of tastes to choose from, like mint, menthol, and e-liquid.
