HeatStick is a product developed by Philip Morris, the makers of Marlboro brand products. HeatSticks are short, cigarette-like sticks. The sticks are heated to a maximum of 660º F (350º C) in a hollow pen-like device called iQOS (pronounced EYE-cohs) to create a tobacco-flavored nicotine vapor. There is no need for liquid nicotine; HeatSticks contain real tobacco.
With the health risks attributed to cigarettes, many smokers are looking for smoking alternatives or quitting all together. Alternative options such as electronic cigarettes are getting a lot of attention as a result. Philip Morris wants HeatSticks to be another alternative option. HeatSticks are bing tested internationally and could eventually be marketed in the U.S. in the future.
