Nicotine pouch
Nicotine pouches are small rectangles containing nicotine, flavourings and other ingredients. Unlike snus, they do not include tobacco leaf, dust, or stem. The nicotine may either be derived from tobacco plants or may be synthetic.
Like with snus or dipping tobacco the user puts a pouch between their lip and gum, and leaves it there while the nicotine and taste is being released. The nicotine enters the bloodstream via mucous membranes in the gums. When finished, the pouch is disposed of. The small pouches differ from chewing tobacco in that the user does not need to spit, since the contents of the pouches stay inside the pouches during use.
There is limited independent testing of the constituents, exposure, or biomarkers of effects for nicotine pouches, although independent research is now emerging. Since 2021, sales of nicotine pouches have grown exponentially with Zyn as the global leader. This popularity has led to controversy among government regulators who view the product's appeal to youth as concerning.
