MentholMenthol is an organic compound, more specifically a monoterpenoid, made synthetically or obtained from the oils of corn mint, peppermint, or other mints. It is a waxy, clear or white crystalline substance, which is solid at room temperature and melts slightly above. The main form of menthol occurring in nature is (−)-menthol, which is assigned the (1R,2S,5R) configuration. Menthol has local anesthetic and counterirritant qualities, and it is widely used to relieve minor throat irritation.
Buccal administrationBuccal administration is a topical route of administration by which drugs held or applied in the buccal (ˈbʌkəl) area (in the cheek) diffuse through the oral mucosa (tissues which line the mouth) and enter directly into the bloodstream. Buccal administration may provide better bioavailability of some drugs and a more rapid onset of action compared to oral administration because the medication does not pass through the digestive system and thereby avoids first pass metabolism.
Construction of electronic cigarettesAn electronic cigarette is a handheld battery-powered vaporizer that simulates smoking, but without tobacco combustion. E-cigarette components include a mouthpiece (drip tip), a cartridge (liquid storage area), a heating element/atomizer, a microprocessor, a battery, and some of them have an LED light on the end. An atomizer consists of a small heating element, or coil, that vaporizes e-liquid and a wicking material that draws liquid onto the coil.
Nicotine withdrawalNicotine 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 or 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.
HookahA hookah (Hindustani: (Nastaleeq), हुक़्क़ा (Devanagari), IPA: ˈɦʊqːa; also see other names), shisha, or waterpipe is a single- or multi-stemmed instrument for heating or vaporizing and then smoking either tobacco, flavored tobacco (often muʽassel), or sometimes cannabis, hashish and opium. The smoke is passed through a water basin—often glass-based—before inhalation.
Nicotine marketingNicotine 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 (particularly of sporting events). Expenditures on nicotine marketing are in the tens of billions a year; in the US alone, spending was over US1millionperhourin2016;in2003,per−capitamarketingspendingwas290 per adult smoker, or $45 per inhabitant. Alpha-5 nicotinic acetylcholine receptorThe alpha-5 nicotinic acetylcholine receptor (α5 nAChR) also known as the α5 receptor is a type of ligand gated nicotinic acetylcholine receptor involved in pain regulation. One of the 5 transmembrane subunits of this receptor is the α5 subunit and is transcribed by the CHRNA5 gene. This receptor is commonly associated with nicotine addiction, immunotherapy, cancer, pain and attention. There are two major classes of acetylcholine receptors: nicotinic receptors, which bind to exogenous nicotine, and muscarinic receptors, which bind exogenous muscarine.
Snuff (tobacco)Snuff is a type of smokeless tobacco product made from finely ground or pulverized tobacco leaves. It is snorted or "sniffed" (alternatively sometimes written as "snuffed") into the nasal cavity, delivering a swift hit of nicotine and a lasting flavored scent (especially if flavoring has been blended with the tobacco). Traditionally, it is sniffed or inhaled lightly after a pinch of snuff is either placed onto the back surface of the hand, held pinched between thumb and index finger, or held by a specially made "snuffing" device.
