The law does not require that the amounts of nicotine, tar and carbon monoxide to be indicated on packs of HEETS. Each type of HEETS has approximately the same level of nicotine as the average cigarette, when tested under the same conditions as for cigarettes, in accordance with ISO standards. When using IQOS, carbon monoxide is not produced above environmental levels. IQOS heats tobacco and produces tobacco vapor that is significantly different from tobacco smoke.
All materials used in Philip Morris smoke-free products have been tested and confirmed for their intended use and testing of the PLA filter, when heated did not reveal anything questionable.
During the use of IQOS, the PLA filter changes color and its appearance (i.e. hardens after consumption). This is the natural reaction of this material to heating during which heat is absorbed. The filter does not affect or contribute to the harmfulness of HEETS tobacco vapor.
The central part of the filter in HEETS products is made of polylactic acid (PLA), a biodegradable polymer film that is wrapped in non-porous sheets made of cellulose fibers which are then bent in such a way to cool the tobacco vapor as efficiently as possible. PLA is one of the most widely used biopolymers in the world, obtained from corn starch or sugar cane and has been used for medical purposes for years.

There is real tobacco in the HEETS stick, to which glycerin and water are added.

Yes, IQOS tobacco sticks contain nicotine, which is addictive. Nicotine is naturally present in tobacco. It is released in the vapor that is generated during the IQOS usage.

IQOS Tobacco sticks are made from a specially selected blend of tobacco in order to provide tobacco taste and satisfaction that replicates as much as possible what adult smokers expect.
The tobacco sticks are designed specifically for the IQOS devices. They have an optimal length, diameter and design for the IQOS Holder.
Tobacco sticks are designed for the same duration and number of puffs as cigarettes.
