If you want to stop smoking, several different treatments are available from shops, pharmacies and on prescription to help you beat your addiction and reduce withdrawal symptoms. Medications, nicotine replacement therapies, and behavioral treatment can help people to stop using products that contain nicotine. Any product containing tobacco also contains nicotine. This includes cigarettes, heated tobacco products, cigars, and most e-cigarettes.a b c Bailey SR, Crew EE, Riske EC, Ammerman S, Robinson TN, Killen JD (April 2012).

Nicotine that is found in natural tobacco is primarily (99%) the S-enantiomer. [157]Conversely, the most common chemistry synthetic methods for generating nicotine yields a product that is approximately equal proportions of the S- and R-enantiomers. [158] This suggests that tobacco-derived and synthetic nicotine can be determined by measuring the ratio of the two different enantiomers, although means exist for adjusting the relative levels of the enantiomers or performing a synthesis that only leads to the S-enantiomer. There is limited data on the relative physiological effects of these two enantiomers, especially in people. However, the studies to date indicate that (S)-nicotine is more potent than (R)-nicotine and (S)-nicotine causes stronger sensations or irritation than (R)-nicotine. To date, studies are not adequate to determine the relative addictiveness of the two enantiomers in people. Structure of protonated nicotine (left) and structure of the counterion benzoate (right). This combination is used in some vaping products to increase nicotine delivery to the lung. Nicotine use as a tool for quitting smoking has a good safety history. [34] Animal studies suggest that nicotine may adversely affect cognitive development in adolescence, but the relevance of these findings to human brain development is disputed. [35] [25] At low amounts, it has a mild analgesic effect. [36] According to the International Agency for Research on Cancer, "nicotine is not generally considered to be a carcinogen." [37] [38]

A racing heartbeat may mean the dose of nicotine is too high, and people can talk with a healthcare professional about lowering the dosage. The Elfbar 600 provides fruity and menthol-based flavour profiles, available in zero (0%) nicotine. 0mg (0%) Nicotine may also temporarily improve concentration and memory. However, long-term smoking of cigarettes may link to a decline in cognitive ability and an increased risk of Alzheimer’s disease. Therefore, any short-term benefits on cognitive function do not outweigh the long-term risks from nicotine use.

Bupropion (Zyban) The starting material was an N-substituted pyrrole derivative, which was heated to convert it by a [1,5] sigmatropic shift to the isomer with a carbon bond between the pyrrole and pyridine rings, followed by methylation and selective reduction of the pyrrole ring using tin and hydrochloric acid. [160] [161] Many other syntheses of nicotine, in both racemic and chiral forms have since been published.

[75] Nicotine is highly addictive. [19] [20] Its addictiveness depends on how it is administered. [23] Animal research suggests that monoamine oxidase inhibitors in tobacco smoke may enhance its addictiveness. [25] [26] Nicotine dependence involves aspects of both psychological dependence and physical dependence, since discontinuation of extended use has been shown to produce both affective (e.g., anxiety, irritability, craving, anhedonia) and somatic (mild motor dysfunctions such as tremor) withdrawal symptoms. [1] Withdrawal symptoms peak in one to three days [93] and can persist for several weeks. [94] Some people experience symptoms for 6 months or longer. [95]
