Nicotine pouches, also known as modern oral nicotine products, are small white pouches containing nicotine and other ingredients, but they do not contain tobacco leaf, dust, or stem. The nicotine in these pouches may be derived from tobacco plants or may be in the form of nicotine powder. Users place a pouch between their lip and gum, and leave it there while the nicotine and flavor are released. Once finished, the pouch is disposed of. Unlike chewing tobacco, users do not need to spit, as the contents of the pouches stay inside during use. Nicotine pouches typically contain food-grade fillers, sweeteners, and flavorings, with the main ingredient being plant fiber. Some common brands of nicotine pouches include Zyn, On!, and Velo, and they come in various flavors. Nicotine pouches are not regulated as strictly as smoked tobacco products by the Food and Drug Administration (FDA) and their long-term health impact is still unknown. They may entice youth and young adults due to their availability in an array of flavors and their unobtrusive use. Side effects of using nicotine pouches can include irritation of the gums, sore mouth, hiccups, and nausea. It is important to note that more research needs to be done to determine the safety and effectiveness of nicotine pouches.
