Upper deckies are nicotine pouches placed between your upper lip and gum. The term is slang that blew up on TikTok in late 2022, when a user named @cheddy222 posted a sing-song video riffing on phrases like “upper decky and lip pillows, ferda.” The word “ferda,” short for “for the boys,” comes from the Canadian comedy show Letterkenny, and the whole video leaned into frat-and-hockey culture humor. The name stuck, and now “upper decky” is widely used to describe the act of tucking a nicotine pouch into your upper lip.
Why “Upper Decky” and Not Just Nicotine Pouch
The slang is really about placement. “Upper deck” refers to the upper lip, and a “lip pillow” is a nickname for the pouch itself because of its soft, cushion-like feel against the gum. Whether someone uses ZYN, VELO, On!, or any other brand, calling it an upper decky just means they’re parking it up top. The terminology has nothing to do with a specific product.
What’s Actually Inside a Nicotine Pouch
Unlike traditional chewing tobacco or snus, nicotine pouches contain no tobacco leaf. The pouch is filled with plant-based fibers (microcrystalline cellulose), pH adjusters like sodium carbonate and sodium bicarbonate, sweeteners, flavorings, and a pharmaceutical-grade nicotine salt. The nicotine is either extracted from tobacco plants and then purified, or synthesized in a lab. Either way, it meets pharmaceutical purity standards, which means it’s free of the natural impurities and plant toxins found in actual tobacco leaf.
Most popular brands come in strengths of 3 mg or 6 mg per pouch, though some products on the market go much higher, up to 20 or even 30 mg.
How Nicotine Pouches Differ From Snus
Snus is a traditional Scandinavian product that contains ground, pasteurized tobacco mixed with water, salt, and flavorings. You use it the same way: tuck it under the upper lip. But the chemical profiles are very different. When researchers tested nicotine pouches like ZYN for 43 potentially harmful compounds, 38 of them were undetectable. That included all tested nitrosamines and polycyclic aromatic hydrocarbons, two categories of chemicals strongly linked to cancer. Snus, by comparison, contained 19 of those 43 compounds, including five different nitrosamines.
This doesn’t make nicotine pouches harmless, but it does explain why they’re marketed as a cleaner alternative to smokeless tobacco.
What Nicotine Pouches Do to Your Body
Nicotine activates your body’s fight-or-flight system, triggering the release of adrenaline and noradrenaline. The immediate result is a bump in heart rate, blood pressure, and arterial stiffness. Studies show these effects are dose-dependent: a 3 or 4 mg pouch produces a mild response comparable to a nicotine lozenge, while a 20 or 30 mg pouch can deliver nicotine as fast as smoking a cigarette and push blood levels even higher than a single cigarette would.
That speed of delivery matters for addiction. High-dose pouches get nicotine into your bloodstream rapidly enough that the dependence potential is similar to cigarettes. Low-dose pouches carry less risk on that front, but nicotine in any form is habit-forming.
Oral Health Effects
Because the pouch sits directly against your gum tissue, repeated use in the same spot can cause localized damage. Clinical case reports have documented gum recession and white patches (leukoplakia) at the exact sites where young, otherwise healthy men habitually placed their pouches. In one case, a 22-year-old who used pouches daily for 11 months at his upper canine area developed both gum recession and leukoplakia. A 25-year-old with 18 months of daily use showed recession in his upper premolar and canine region.
The likely mechanism is a combination of mechanical pressure from the pouch pressing against tissue and chemical irritation from the pouch contents. Neither case showed widespread gum disease, just damage isolated to the placement site. Rotating where you place the pouch may reduce this risk, though no long-term studies have confirmed that yet.
Who’s Using Them
Nicotine pouch use has been climbing steadily, especially among young people. Among U.S. high school students, usage more than doubled from 1.1% in 2021 to 2.4% in 2024. The broader user base skews toward younger and middle-aged men, people who identify as white, people who already use other tobacco products, and those with lower education and incomes.
Several factors are driving growth. The “tobacco-free” label creates a perception of reduced harm. A wide variety of flavors makes the products appealing to new users. And because many states don’t tax nicotine pouches the same way they tax cigarettes or smokeless tobacco, pouches are often cheaper than other nicotine products.
Regulatory Status in the U.S.
Nicotine pouches occupy a legally complicated space. In April 2022, Congress gave the FDA authority to regulate any tobacco product containing nicotine from any source, including synthetic nicotine. Under that law, nicotine pouch manufacturers must submit a premarket application and receive FDA authorization before legally selling their products. As of now, no synthetic nicotine products have received that authorization. The FDA can issue warning letters, civil penalties, seizures, or injunctions against companies that sell without approval, though enforcement has been inconsistent as the market has expanded rapidly.
