Nicotine is a naturally produced alkaloid in the nightshade family of plants and is widely used recreationally as a stimulant and anxiolytic. As a pharmaceutical drug, it is used for smoking cessation to relieve withdrawal symptoms. Nicotine acts as a receptor agonist at most nicotinic acetylcholine receptors (nAChRs), except at two nicotinic receptor subunits where it acts as a receptor antagonist.
Smoking cessation, usually called quitting smoking or stopping smoking, is the process of discontinuing tobacco smoking. Tobacco smoke contains nicotine, which is addictive and can cause dependence. As a result, nicotine withdrawal often makes the process of quitting difficult.
Nicotine replacement therapy (NRT) is a medically approved way to treat people with tobacco use disorder by taking nicotine through means other than tobacco. It is used to help with quitting smoking or stopping chewing tobacco. It increases the chance of quitting tobacco smoking by about 55%. Often it is used along with other behavioral techniques. NRT has also been used to treat ulcerative colitis. Types of NRT include the adhesive patch, chewing gum, lozenges, nose spray, and inhaler. The use of multiple types of NRT at a time may increase effectiveness.
A nicotine patch is a transdermal patch that releases nicotine into the body through the skin. It is used in nicotine replacement therapy (NRT), a process for smoking cessation. Endorsed and approved by the U.S. Food and Drug Administration (FDA), it is considered one of the safer NRTs available for the treatment of tobacco use disorder.
Nicotine gum is a chewing gum containing the active ingredient nicotine polacrilex. It is a type of nicotine replacement therapy (NRT) used alone or in combination with other pharmacotherapy for smoking cessation and for quitting smokeless tobacco.
Nicorette is the brand name of a number of products for nicotine replacement therapy (NRT) that contain nicotine polacrilex. Developed in the late 1970s in Sweden by AB Leo in the form of a chewing gum, Nicorette was the first nicotine replacement product on the market.
Nicotine marketing is the marketing of nicotine-containing products or use. Traditionally, the tobacco industry markets cigarette smoking, but it is increasingly marketing other products, such as electronic cigarettes and heated tobacco products. Products are marketed through social media, stealth marketing, mass media, and sponsorship. Expenditures on nicotine marketing are in the tens of billions a year; in the US alone, spending was over US$1 million per hour in 2016; in 2003, per-capita marketing spending was $290 per adult smoker, or $45 per inhabitant. Nicotine marketing is increasingly regulated; some forms of nicotine advertising are banned in many countries. The World Health Organization recommends a complete tobacco advertising ban.
An herbal cigarette is a cigarette that usually does not contain any tobacco or nicotine, instead being composed of a mixture of various herbs and/or other plant material. However, Chinese herbal cigarettes contain tobacco and nicotine with herbs added, unlike European and North American herbal cigarettes which have tobacco and nicotine omitted. Like herbal smokeless tobacco, they are often used as a substitute for standard tobacco products. Herbal cigarettes are often advertised as a smoking cessation aid. They are also used in acting scenes by performers who are non-smokers, or where anti-smoking legislation prohibits the use of tobacco in public spaces. Herbal cigarettes can carry carcinogens.
Nicotine withdrawal is a group of symptoms that occur in the first few weeks after stopping or decreasing use of nicotine. Symptoms include intense cravings for nicotine, anger or irritability, anxiety, depression, impatience, trouble sleeping, restlessness, hunger, weight gain, and difficulty concentrating. Withdrawal symptoms make it harder to quit nicotine products, and most methods for quitting smoking involve reducing nicotine withdrawal. Quit smoking programs can make it easier to quit. Nicotine withdrawal is recognized in both the American Psychiatric Association Diagnostic and Statistical Manual (DSM) and the WHO International Classification of Diseases (ICD).
Tobacco harm reduction (THR) is a public health strategy to lower the health risks to individuals and wider society associated with using tobacco products. It is an example of the concept of harm reduction, a strategy for dealing with the use of drugs. Tobacco smoking is widely acknowledged as a leading cause of illness and death, and reducing smoking is vital to public health.
An electronic cigarette (e-cigarette), commonly called a vape, is a device that simulates tobacco smoking. It consists of an atomizer, a power source such as a battery, and a container such as a cartridge or tank. Instead of smoke, the user inhales vapor. As such, using an e-cigarette is often called "vaping". The atomizer is a heating element that vaporizes a liquid solution called e-liquid, which quickly cools into an aerosol of tiny droplets, vapor and air. The vapor mainly comprises propylene glycol and/or glycerin, usually with nicotine and flavoring. Its exact composition varies, and depends on several things including user behavior.
Nicotine dependence is a state of substance dependence on nicotine. It is a chronic, relapsing disease characterized by a compulsive craving to use the drug despite social consequences, loss of control over drug intake, and the emergence of withdrawal symptoms. Tolerance is another component of drug dependence. Nicotine dependence develops over time as an individual continues to use nicotine. While cigarettes are the most commonly used tobacco product, all forms of tobacco use—including smokeless tobacco and e-cigarette use—can cause dependence. Nicotine dependence is a serious public health problem because it leads to continued tobacco use and the associated negative health effects. Tobacco use is one of the leading preventable causes of death worldwide, causing more than 8 million deaths per year and killing half of its users who do not quit. Current smokers are estimated to die an average of 10 years earlier than non-smokers.
Nicotine Anonymous (NicA) is a twelve-step program founded in 1982 for people desiring to quit smoking and live free of nicotine. As of July 2017, there are over 700 face-to-face meetings in 32 countries worldwide with the majority of these meetings occurring in the United States, Iran, India, Canada, Brazil, the United Kingdom, Australia, Russia and in various online community and social media platforms.. NicA maintains that total abstinence from nicotine is necessary for recovery. NicA defines abstinence as “a state that begins when all use of nicotine ceases.
A nicotine lozenge is a modified-release dosage tablet that contains a dose of nicotine polacrilex, which dissolves slowly in the mouth to release nicotine over the course of 20 to 30 minutes. Nicotine lozenges are intended to help individuals quit smoking and are generally an over-the-counter medication. Nicotine lozenges are commonly found in 2 mg and 4 mg strengths, although other strengths may be found. The nicotine is absorbed through the lining of the mouth and enters the blood vessels. It is used as an aid in nicotine replacement therapy (NRT), a process for smoking cessation.
Schizophrenia and tobacco smoking have been historically associated. Smoking is known to harm the health of people with schizophrenia.

Smoking in Iceland is banned in restaurants, cafés, bars and night clubs as of June 2007. A large majority of Icelanders approve of the ban. At the time the ban went into effect, almost one in four Icelandic people were smokers.
The scientific community in the United States and Europe are primarily concerned with the possible effect of electronic cigarette use on public health. There is concern among public health experts that e-cigarettes could renormalize smoking, weaken measures to control tobacco, and serve as a gateway for smoking among youth. The public health community is divided over whether to support e-cigarettes, because their safety and efficacy for quitting smoking is unclear. Many in the public health community acknowledge the potential for their quitting smoking and decreasing harm benefits, but there remains a concern over their long-term safety and potential for a new era of users to get addicted to nicotine and then tobacco. There is concern among tobacco control academics and advocates that prevalent universal vaping "will bring its own distinct but as yet unknown health risks in the same way tobacco smoking did, as a result of chronic exposure", among other things.
