Product Information

Nicotine was originally isolated from the tobacco plant in 1828 by chemists Wilhelm Heinrich Posselt and Karl Ludwig Reimann from Germany, who believed it was a poison. [179] [180] Its chemical empirical formula was described by Melsens in 1843, [181] its structure was discovered by Adolf Pinner and Richard Wolffenstein in 1893, [182] [183] [184] [ clarification needed] and it was first synthesized by Amé Pictet and A. Rotschy in 1904. [161] [185]

A hookah or hubble-bubble is a sort of tobacco pipe where smoke is drawn through a bottle of water. The tobacco (shisha) is flavoured and sweetened. People who smoke hookah regularly also have an increased chance of smoking related diseases such as lung cancer. The N-methyl-Δ 1-pyrrollidium cation used in the synthesis of nicotine is an intermediate in the synthesis of tropane-derived alkaloids. Biosynthesis begins with decarboxylation of ornithine by ornithine decarboxylase (ODC) to produce putrescine. Putrescine is then converted into N-methyl putrescine via methylation by SAM catalyzed by putrescine N-methyltransferase (PMT). N-methyl putrescine then undergoes deamination into 4-methylaminobutanal by the N-methyl putrescine oxidase (MPO) enzyme, 4-methylaminobutanal then spontaneously cyclize into N-methyl-Δ 1-pyrrollidium cation.

It is unlikely that a person would overdose on nicotine through smoking alone. The US Food and Drug Administration (FDA) stated in 2013 that there are no significant safety concerns associated with the use of more than one form of over-the-counter (OTC) nicotine replacement therapy at the same time, or using OTC NRT at the same time as another nicotine-containing product, like cigarettes. [120] The median lethal dose of nicotine in humans is unknown. [42] [27] Nevertheless, nicotine has a relatively high toxicity in comparison to many other alkaloids such as caffeine, which has an LD 50 of 127mg/kg when administered to mice. [121] At sufficiently high doses, it is associated with nicotine poisoning, [39] which, while common in children (in whom poisonous and lethal levels occur at lower doses per kilogram of body weight [36]) rarely results in significant morbidity or death. [41] The estimated lower dose limit for fatal outcomes is 500–1,000mg of ingested nicotine for an adult (6.5–13mg/kg). [25] [27]

Centers for Disease Control and Prevention. Current cigarette smoking among adults in the United States. A 2016 review of the cardiovascular toxicity of nicotine concluded, "Based on current knowledge, we believe that the cardiovascular risks of nicotine from e-cigarette use in people without cardiovascular disease are quite low. We have concerns that nicotine from e-cigarettes could pose some risk for users with cardiovascular disease." [90] Blood pressure [ edit ] Nicotine comes from the Nicotiana species, which are tobacco plants and part of the nightshade family. Tobacco plants originated in South America before spreading to North America, Africa, and Australia.Historical attempts to develop ways for people to continue smoking cigarettes whilst reducing overall harm, for example by using low-tar varieties, have proved ineffective.
