Zyn is a tobacco-free nicotine pouch designed to deliver nicotine without smoke, vapor, or chewing tobacco. You place a small pouch between your gum and upper lip, where nicotine absorbs through the oral tissue. The product is made by Swedish Match, now owned by Philip Morris International, and is primarily marketed as an alternative for adults who already use cigarettes or smokeless tobacco.
How Zyn Works
Each Zyn pouch contains pharmaceutical-grade nicotine salt along with food-grade fillers, stabilizers, sweeteners, and flavorings. There is no actual tobacco leaf inside. You tuck the pouch between your upper lip and gum, where it sits for anywhere from 5 to 60 minutes. During that time, nicotine releases slowly and absorbs through the lining of your mouth into your bloodstream. Most users notice a mild tingling sensation when they first place the pouch, which fades after a few minutes.
The pouches come in multiple nicotine strengths. In the U.S., the most common options are 3 mg and 6 mg per pouch. Internationally, strengths range higher, from 9 mg up to 16.5 mg in extra-strong and max varieties. Higher-strength pouches also tend to come in a larger “slim” size, while lower-strength options use a smaller mini pouch that sits more discreetly.
Why People Use It
The core purpose of Zyn is to provide nicotine in a form that avoids the combustion and toxic byproducts of cigarettes. Burning tobacco generates thousands of chemicals, dozens of which cause cancer. Zyn contains none of those combustion-related toxins, which is a meaningful difference from a health-risk standpoint. Harvard’s T.H. Chan School of Public Health has noted that Zyn presents significantly lower health risks than smoking because it lacks the cancer-causing chemicals found in cigarette smoke.
For adults who smoke and haven’t been able to quit, Zyn can serve as a way to reduce exposure to those harmful chemicals while still getting nicotine. That said, the product is not marketed or approved as a quit-smoking aid. It delivers nicotine, and nicotine itself is addictive. People who don’t already use tobacco or nicotine products have no reason to start using Zyn.
FDA Authorization
The FDA authorized 20 Zyn nicotine pouch products for legal marketing in the United States after what it described as an extensive scientific review. The agency found that these products have the potential to benefit adults who smoke cigarettes or use other smokeless tobacco and completely switch to Zyn. That benefit was judged sufficient to outweigh the risks, including the risk of youth uptake.
This authorization is not the same as FDA approval. The FDA was clear: no tobacco product is safe, and the marketing authorization simply means these specific products can be legally sold to adults 21 and older. It does not endorse them as healthy or risk-free.
What’s Actually Inside
Zyn’s ingredient list is relatively short compared to traditional smokeless tobacco. The nicotine comes in the form of nicotine bitartrate dihydrate, a nicotine salt. The rest of the pouch is built from plant-based stabilizers that maintain consistency, fillers like cellulose and gum arabic that give the pouch its bulk, and pH balancers that help nicotine absorb through oral tissue. Sweeteners and flavorings round out the formula. Because there is no tobacco leaf, Zyn doesn’t produce the brown saliva associated with dip or chewing tobacco, and most users don’t need to spit.
Side Effects and Health Risks
Nicotine, regardless of how it’s delivered, affects the body in several ways. The most common side effects from nicotine pouches include nausea, hiccups, dizziness, and headaches, particularly for new users or those who choose a strength that’s too high. An upset stomach is also reported frequently.
Oral health is a specific concern with any product that sits against your gums for extended periods. Regular use of nicotine pouches can cause gum irritation and recession, dry mouth, soreness, and may contribute to tooth decay and cavities over time. These effects tend to be more pronounced in people who use pouches continuously throughout the day.
Nicotine also raises heart rate and blood pressure, increases the risk of heart disease and stroke, and can damage blood vessels. There is growing evidence linking nicotine use in any form to mental health effects, including increased rates of depression and anxiety. The American Cancer Society notes that nicotine itself may raise cancer risk, separate from the well-established cancer risks of tobacco smoke. Long-term data on nicotine pouches specifically is still limited since the product category is relatively new.
How Zyn Compares to Cigarettes
The comparison matters because it’s the reason the FDA allowed the product on the market. Cigarette smoke contains tar, carbon monoxide, formaldehyde, and dozens of known carcinogens. Zyn contains none of these because nothing is burned or heated. For a pack-a-day smoker who fully switches to nicotine pouches, the reduction in toxic chemical exposure is substantial.
The key word is “fully switches.” Using Zyn alongside cigarettes, sometimes called dual use, dilutes or eliminates that benefit. The FDA’s authorization specifically cited the advantage for adults who completely replace cigarettes or smokeless tobacco with Zyn. If you’re still smoking the same number of cigarettes and adding pouches on top, you’re just increasing your total nicotine intake without meaningfully reducing your exposure to combustion toxins.
It’s also worth understanding that “lower risk than cigarettes” is a low bar. Cigarettes are the single deadliest consumer product ever made. Being safer than cigarettes does not make something safe, and nicotine pouches still carry real health consequences, particularly for cardiovascular health and oral tissue.
