ZYN is a small, white pouch containing nicotine that you place between your gum and upper lip. It doesn’t contain tobacco leaf, and there’s nothing to smoke, vape, or spit. The nicotine is absorbed directly through the lining of your mouth into your bloodstream, delivering a hit similar to what you’d get from a cigarette or vape but without inhaling anything into your lungs.
What’s Inside a ZYN Pouch
Each pouch contains pharmaceutical-grade nicotine in salt form (nicotine bitartrate dihydrate), along with food-grade fillers, sweeteners, and flavorings. The filler materials, including plant-based cellulose and gum arabic, give the pouch its shape and bulk. Sodium carbonate and sodium bicarbonate act as pH adjusters, which is important because the pH level directly controls how much nicotine your body can absorb. At higher pH levels, more nicotine converts to a form that passes through mouth tissue more easily.
In the U.S., ZYN comes in 3 mg and 6 mg nicotine strengths across ten flavors: Cool Mint, Spearmint, Peppermint, Wintergreen, Chill, Menthol, Citrus, Cinnamon, Coffee, and Smooth. Some international markets carry strengths as low as 1.5 mg and as high as 11 mg.
How You Use It
You tuck the pouch between your upper lip and gum and leave it there. Most people feel a mild tingling sensation within the first minute or two as nicotine begins releasing into saliva. The recommended window is between 5 and 60 minutes per pouch. Once you’re done, you remove it and throw it away. There’s no need to spit, and the pouches are small enough that most people around you won’t notice one is in.
How Nicotine Gets Into Your System
Saliva dissolves the nicotine from the pouch, and it then passes through the soft tissue on the inside of your cheek (the buccal mucosa). This tissue is thinner and more permeable than the tougher tissue directly on your gums, which is why pouch placement matters. How quickly the nicotine absorbs depends on several factors: the strength of the pouch, how much saliva you produce, how long you keep it in, and the pH of the formulation.
Research on high-strength pouches (20 mg and 30 mg, available in some markets) has shown they can produce peak nicotine blood levels comparable to or even higher than smoking a cigarette. The 3 mg and 6 mg pouches sold in the U.S. deliver considerably less nicotine per use.
Effects on the Body
Nicotine is a stimulant regardless of how it enters your body. It increases heart rate, raises blood pressure, and triggers the release of brain chemicals that create a sense of alertness and mild pleasure. Clinical studies confirm that nicotine pouches cause dose-dependent increases in heart rate, blood pressure, and arterial stiffness shortly after use. At higher doses, these cardiovascular effects are comparable in magnitude to smoking a cigarette.
Nicotine is also highly addictive. Regular use of ZYN can lead to physical dependence, meaning you’ll experience cravings and withdrawal symptoms (irritability, difficulty concentrating, restlessness) if you stop.
Oral Health Concerns
Because the pouch sits directly against gum tissue for extended periods, there are specific risks to your mouth. The physical contact can cause mechanical irritation and injury to the gums. Lab studies have found that extracts from nicotine pouches are toxic to gum cells, and the close proximity to tissue allows those chemicals to concentrate in the local area. Frequent users of oral nicotine and tobacco products have shown higher rates of gum recession and attachment loss, where the gum tissue pulls away from the tooth.
Common short-term side effects include soreness, tingling, or slight swelling at the placement site. Some people also experience hiccups, nausea, or a burning sensation, especially when first starting or when using a higher strength than they’re accustomed to.
How ZYN Compares to Cigarettes and Vapes
ZYN eliminates two major sources of harm found in cigarettes: combustion and tobacco leaf. Burning tobacco produces tar, carbon monoxide, and thousands of toxic chemicals. Vaping avoids combustion but still delivers an aerosol that can contain metals like lead, cadmium, and nickel, along with formaldehyde. Nicotine pouches bypass the lungs entirely, removing inhalation-related risks from the equation.
That said, the American Heart Association notes that nicotine pouches still contain high levels of nicotine, and the long-term health effects remain under study. Being lower-risk than cigarettes is not the same as being safe. The nicotine itself carries cardiovascular risks and addiction potential regardless of the delivery method.
FDA Status and Legal Standing
The FDA authorized 20 ZYN products for legal marketing in the U.S. after a scientific review through the premarket tobacco product application (PMTA) pathway. This covers all ten flavors in both the 3 mg and 6 mg strengths. The authorization means these specific products can be legally sold to adults 21 and older, but the FDA was explicit: authorization is not the same as approval, and it does not mean the products are safe.
The marketing orders come with strict advertising restrictions. ZYN’s digital, TV, and radio ads must be targeted to adults 21 and older, and the company is required to track and report the demographics of audiences reached by its advertising. You must be 21 to purchase ZYN in the United States, and most retailers require age verification at the point of sale or during online checkout.
