Some information in this guide is temporal (relating to time)—specifically, the stock price of UST is dependent upon date of reading. Studies may become outdated in time, and SWIM (or others) will hopefully add any new research contributing to or contradicting the information below to this thread. Smokeless Products: Gum: Brand names include Nicorette, Commit, and Nicotrol. Primarily used as a stop-smoking aid. Gum typically contains either 2mg or 4mg of nicotine. The most common method to quit smoking using these gums is to chew a piece every one to two hours for six weeks, a piece every two to four hours for the next three weeks, and a piece every four to eight hours for three week. The 2mg gum is targeted towards people who smoke less than 25 cigarettes a day; the 4mg gum is target towards people who smoke more than 25 cigarettes a day. This product can be used regardless if the user intends on quitting smoking or not, but because the gum is more expensive than other forms of tobacco, it typically isn’t used recreationally. Patches: Brand names include Nicoderm CQ, Nicotrol, and Habitrol. Primarily used as stop-smoking aid. Patches generally contain 21mg, 14mg, or 7mg of nicotine. Product is applied to the body daily, and like the gum, the user is supposed to lower their daily nicotine intake by switching to a patch with lower nicotine content after a certain number of weeks. This typically means the user wears their starting patch for six weeks and nicotine patches with less nicotine content for two weeks until the user has kicked the habit. Like the gum, because this product is more expensive than other forms of tobacco, it typically isn’t used recreationally. Hand Gel: Brand names include Nicogel. A relatively recent product, nicotine hand gel is applied to the users' skin either by wiping their hands with single-use packets or by dispensing 1-2 presses from a pump. This product may be an effective stop-smoking aid, but it is target towards users who want nicotine where they cannot smoke (such as smoke-free bars). Its makers claim the gel contains no carcinogens or cancer-causing agents 1. Chew: Brand names include Redman and Levi Garrett. Chewing tobacco is an age-old way of using nicotine and was very popular for baseball players to use in the last century. Chew comes in three forms: twist, plug, and scrap. Twist tobacco is rolled tobacco leaves twisted around each other like a rope; plug tobacco is made by pressing cured tobacco leaves together in a syrup (which the user, like twist, cuts a piece off the plug to use); and scrap (loose-leaf) tobacco, the most common form of chew, where the user grabs a “pinch” of shredded tobacco and puts it in the back of their jaw between their gum and lip. Users occasionally chew on the tobacco to excrete flavor and nicotine (which is absorbed orally) and spit their saliva into a tin or on the ground. Longtime users are known to swallow their spit; for most users, this causes nausea and vomiting. Beginners often feel light headed or drunk when trying this product and sometimes vomit. Dip: Brand names include Skoal and Copenhagen. Dip is moist, shredded tobacco leaves intended for oral use. Like loose-leaf chew, the user grabs a pinch of the tobacco and places it between their gum and lip. To get a good pinch, users “pack” their tin using a method sometimes called the dip snap or by hitting the tin against a hard surface. This condenses the tobacco into a corner of the tin making it easier to grab. Some brands offer teabag-looking pouches for users, which contain the tobacco. This is put in the mouth the same way as the shredded leaves are, and are generally used by beginners or for those who don’t want to deal with how messy loose-leaf tobacco can be. Like chew users, dip users spit their saliva out to avoid nausea. Longtime dip users also are known to swallow spit, and beginners also feel intoxicated (or sick) after use. The popularity of dipping tobacco is rising, as evident by the climbing stock price of the U.S. Smokeless Tobacco company (UST) 2. Dipping tobacco has recently, by some, been considered a safer, but not harmless, alternative to smoking 3,4. This judgment is not conclusive, as the severity of the role tobacco-specific nitrosamines play in the causes of cancer are disputed. Snus: Popular in Sweden, Snus is used like dipping tobacco however the saliva is not spit out. Snus is dried (as opposed to moist), and is sometimes salted to avoid excessive salivation. Some snus brands also release pouch products. Snus contains lower concentrations of tobacco-specific nitrosamines than moist tobacco and is also regarded as a more safe, but not harmless, alternative to smoking 5. Snuff: Snuff is shredded, dry tobacco (sometimes called European snuff) that is typically flavoured. Users sniff the product into their nose for nicotine absorption; however, this product is not intended to get past the nose (and into the sinuses or throat). Snuff use is less common today when compared with the seventeenth and eighteen centuries. References: 1. Gel Could Help Satisfy Nicotine Cravings (NBC) 2.
