Tobacco products include any product made from tobacco, derived from tobacco, or containing nicotine that is intended for human consumption. That covers far more than cigarettes. The category spans combustible products like cigars and pipe tobacco, smokeless products like chewing tobacco and snuff, electronic vaping devices, hookah tobacco, heated tobacco devices, nicotine pouches, and dissolvable tobacco. Under U.S. federal law, the term also includes any component, part, or accessory of these products.
Combustible Tobacco Products
Combustible tobacco products are lit on fire and inhaled. They include cigarettes, cigars (from large premium cigars down to small cigarillos), and pipe tobacco. This category causes the vast majority of tobacco-related death and disease because burning tobacco generates thousands of chemical byproducts, many of them toxic or cancer-causing.
Cigarettes are the most widely used tobacco product worldwide. They contain shredded tobacco wrapped in paper, usually with a filter. Cigars use tobacco leaf as the wrapper and range from slim, cigarette-sized cigarillos to large hand-rolled varieties. Pipe tobacco is loose-cut and burned in a bowl, with smoke drawn through a stem.
Smokeless Tobacco Products
Smokeless tobacco is not burned. Most forms are placed between the gum and cheek or lip, where nicotine absorbs through the lining of the mouth. The two main categories sold in the U.S. are chewing tobacco and snuff.
Chewing tobacco comes as loose leaf, compressed plugs, or braided twists of cured tobacco. Snuff is finely cut or powdered tobacco. Dry snuff is typically sniffed through the nostrils, while moist snuff (commonly called “dip”) is tucked inside the lip. Snus is a type of moist snuff, often sold in small pre-portioned pouches, that originated in Scandinavia and is placed under the upper lip.
Dissolvable tobacco products are a newer subcategory. These are made from finely milled tobacco pressed into orbs, thin strips, lozenges, or small sticks resembling toothpicks. They deliver nicotine as they slowly dissolve in your mouth. Brands like Ariva, Stonewall, and Camel Orbs have been marketed in the U.S., though availability has been limited.
E-Cigarettes and Vaping Devices
Electronic nicotine delivery systems go by many names: vapes, vaporizers, vape pens, e-cigarettes, e-cigs, e-cigars, e-pipes, and hookah pens. They all work on the same basic principle. A battery-powered heating element vaporizes a liquid solution that typically contains nicotine, flavorings, and a carrier fluid. The user inhales the resulting aerosol.
These devices range from small, disposable units that look like USB drives to larger refillable systems with adjustable settings. Despite not containing tobacco leaf, they are regulated as tobacco products in the U.S. because most use nicotine derived from tobacco plants. Some products use synthetic nicotine manufactured in a laboratory. There is little chemical difference between the two forms of nicotine, though the distinction has mattered for regulation. Manufacturers have at times used synthetic nicotine, or even nicotine-like chemical substitutes, specifically to try to sidestep federal oversight.
Hookah Tobacco
Hookah tobacco, also called shisha, maassel, or waterpipe tobacco, is a mixture of tobacco, sweeteners, and flavoring. It is smoked using a waterpipe device: charcoal or electrically heated air passes through the tobacco mixture, and the resulting smoke is drawn through a water-filled chamber before being inhaled through a hose.
A common misconception is that the water filters out harmful substances. It does cool the smoke, but it does not remove the toxicants produced by burning the tobacco and charcoal. A single hookah session can last 30 to 60 minutes or longer, exposing the user to a significant volume of smoke.
Heated Tobacco Products
Heated tobacco products sit between traditional cigarettes and e-cigarettes. They contain real processed tobacco leaf, but instead of lighting it on fire, an electronic device heats it to temperatures up to about 350°C (roughly 660°F), well below the 600°C or higher reached by a burning cigarette tip. This produces a nicotine-containing aerosol without full combustion.
The most common design uses small tobacco-filled sticks that resemble short cigarettes. You insert the stick into a battery-powered holder that heats the tobacco from either an internal blade or an external heating element. Because the tobacco is heated rather than burned, these products generate lower levels of some harmful chemicals compared to cigarettes. They still expose users to nicotine and other toxicants.
Nicotine Pouches
Nicotine pouches are small, white, pre-portioned sachets placed between the gum and lip, similar to snus. The key difference is that they contain no tobacco leaf at all. Instead, they deliver nicotine through a filler material mixed with flavorings and either tobacco-derived or synthetic nicotine. Products marketed as “tobacco-free” typically use synthetic nicotine, though the nicotine itself is chemically nearly identical to what comes from a tobacco plant.
These pouches have grown rapidly in popularity. They produce no smoke, no vapor, and no need to spit, making them discreet and easy to use in settings where other tobacco products are impractical.
What’s Actually in These Products
The FDA has identified 93 harmful or potentially harmful chemicals in tobacco products and tobacco smoke. These fall into several categories based on the type of damage they cause: cancer-causing agents, substances toxic to the lungs, heart, or reproductive system, and addictive compounds.
Some of the most notable include formaldehyde and benzene (both carcinogens), carbon monoxide (which reduces oxygen delivery in the blood), arsenic, lead, cadmium, and several radioactive elements including polonium-210. Nicotine itself is classified as addictive and as a reproductive and developmental toxicant, meaning it poses particular risks during pregnancy.
Not every tobacco product exposes you to all 93 chemicals. Combustible products generate the widest range because burning tobacco at high temperatures creates new compounds through chemical reactions. Smokeless products skip the combustion byproducts but still contain cancer-causing chemicals called nitrosamines that form during the curing process. E-cigarettes produce fewer known toxicants than cigarettes, but their aerosol is not harmless, and the long-term effects of inhaling vaporized flavoring compounds remain an open question.
How These Products Are Regulated
In the United States, the FDA has authority over all products made or derived from tobacco, as well as products containing nicotine from any source intended for human consumption. This broad definition was designed to capture the full range of products on the market, from traditional cigarettes to modern nicotine pouches with synthetic nicotine.
The definition explicitly excludes products that qualify as drugs, medical devices, or foods under federal law, provided those products contain no nicotine or only trace amounts of naturally occurring nicotine. Nicotine replacement therapies like patches and gum, for example, are regulated as drugs rather than tobacco products.
Regulation has struggled to keep pace with innovation. Some manufacturers have recently turned to nicotine analogues, molecules that are chemically similar to nicotine but technically distinct, to argue their products fall outside the legal definition of a tobacco product. This cat-and-mouse dynamic between product designers and regulators continues to evolve.
