Nicotine is addictive.  However, it is not the main cause of smoking related diseases. ZYN contains nicotine and is for adults who would otherwise continue to smoke or use nicotine products.

We state that ZYN releases on average 99% less harmful chemicals compared to cigarettes. The percentage (99%) refers to the average reduction of 9 harmful chemicals the World Health Organization recommends to reduce in cigarette smoke. These do not include nicotine. To this effect, we collect smoke under the Health Canada Intense machine-smoking regime (55 mL puff volume, 2 second puff duration, 30 second interval puff) from one stick of a reference cigarette, and  compare with the extract from a full use of one nicotine pouch.

The reference cigarette is the cigarette independently designed by the University of Kentucky in the US for scientific research purposes. It is a comparator commonly used in tobacco research, which allows the data of a given study to be compared to that of another study. These research cigarettes are not commercially available to consumers.
