Overview
Snus is made from air-dried/pasteurized tobaccos from various parts of the world. In earlier times, tobacco for making snus was laid out for drying in Scania and Mälardalen, Sweden. Later, Kentucky tobaccos were used. The ground tobacco is mixed with water, salt, an alkalizing agent such as sodium carbonate or sodium bicarbonate (E500), and aroma, and is prepared through heating under pressure. After the heating process, food grade aromas are typically added. In Sweden, snus is regulated as a food product and, for this reason, all ingredients are listed on the label of each individual package (can) of snus. Moist snus contains more than 50% water, and the average use of snus in Sweden is approximately 800 grams (16 units) per person each year. About 12% (1.1 million people) of the population in Sweden use snus.[18] Unlike dipping tobacco and chew, most snus does not undergo the fermentation process, but is instead steam-pasteurized. Pasteurization inhibits the growth of bacteria that facilitate the formation of tobacco-specific nitrosamines, while preserving the desired texture and mouthfeel of the snus. The absorption of nicotine, the desired primary alkaloid in tobacco, greatly depends on the nicotine content in the snus and the pH of the final product.[19] A voluntary quality standard for snus products has been introduced (Gothiatek) that sets maximum levels for certain controversial constituents including nitrosamines, heavy metals, and polyaromatic hydrocarbons. Most manufacturers of Scandinavian type snus adhere to this standard.
Snus is sold in containers of various sizes, originally made of porcelain, wood, silver, or gold. Portioned snus usually comes in plastic tins of 20 to 24 portions, containing about 0.75 to 1 gram of snus each, while loose snus is mostly sold in wax coated cardboard containers with plastic lids (similar to dip snuff), at 42 g (50 g before 2008). Mini-portion and medium-portion snus are increasingly popular formats. Most of these products come in tins containing 20 portions, of either 0.65 or 0.5 grams each for a total of just under 13 or 10 grams, particularly with those for whom concealing their use of smokeless tobacco in places is of utmost importance.
Snus is available in two main types:
Portioned snus comes in three sizes: mini, normal/large, and maxi. The weights vary, but most packages disclose the net weight. Mini portions weigh around 0.5 g, normal portions weigh 0.8 to 1 g, and maxi portions weigh up to 1.7 g. Some brands offer regular and long versions of the normal size sachet.
The nicotine content varies among brands, with the most common strength being 8 mg per gram of tobacco. Stark (Swedish for "strong") and extra stark varieties have higher nicotine content, with stark varieties containing 11–14 mg and extra stark varieties containing up to 22 mg. Siberia brand has an "Extremely Strong" snus with 43 mg of nicotine per gram of tobacco, the highest available.[21]
- Loose snus is a moist powder that can be shaped into a cylindrical or spherical form using the fingertips or a specialized cylindrical device. This final product is commonly known as a pris (pinch), buga, prilla, or prell (slang). Some individuals, particularly long-time users, opt to simply pinch the tobacco and place it under their upper lip (known as a farmer's pinch or living snus). However, the popularity of loose snus has gradually been overtaken by portioned alternatives.
- Portion snus is a convenient and discreet form of snus that comes in small teabag-like sachets filled with moist powder. It is available in smaller quantities compared to loose powder snus. There are two varieties of portion snus:
- Original portion: This traditional form was introduced in 1973. The sachet material is moisturized during manufacturing, resulting in a brown, moist pouch.
- White portion: This form has a milder taste and slightly slower release. The sachet material is not moisturized during manufacturing, resulting in a white, dry pouch. The tobacco within the portion material has the same moisture content as original portion snus, but the nicotine and flavor are delivered somewhat slower due to the drier sachet. Notably, "white portion" refers to the style, not the color. Some white portion snus use a black material instead of white, yet are still considered "white portion". Examples of such snus include General Onyx, Grovsnus Svart (Black), and Blue Ocean (Blue).
- The Stingfree portion is a patented pouch for snus and modern oral nicotine pouches, approved in the US and Europe. It features a protective side that effectively reduces the burning sensation and irritation on the user's gum and oral mucosa.[20]
Usage
Snus is typically used by being placed under the upper lip. This is true for both loose snus and portion snus. The pris (pressed pellet of loose snus) or pouch is typically left in place for anywhere between 30 and 120 minutes. No spitting is required, but some (especially new users) may prefer to.[22]
Snus is not cured, so it can spoil much faster than cured tobacco. While tobacco-based snus is typically refrigerated for short term storage (up to a few months), it is typically frozen for longer term storage of a year or more. It can stay unrefrigerated for a week or more without spoilage. Some tobacco-based snus products are shipped very dry, so they have extended shelf life without needing any refrigeration. This makes them slower to initially "drip", as there is no appreciable moisture in the packet.
Differences with other oral tobacco products
Some forms of tobacco consumed in the mouth may be categorized as:
Snus, dry snuff, and dipping tobacco are distinct products that some English speaking people may refer to as snuff but are all processed and used in very different ways, each with their own sets of risks.
- Swedish snus: A moist form of smokeless tobacco which is usually placed under the upper lip, and which does not result in the need for spitting. It is sold either as a moist powder known as loose snus, or packaged into pouches known as portion snus. Snus is often mildly flavored with food-grade smoke aroma,
