[33] These include mildly worse mood, stress, anxiety, cognition, and sleep, all of which briefly return to normal with the next cigarette. [33] Smokers have a worse mood than they typically would have if they were not nicotine-dependent; they experience normal moods only immediately after smoking. [33] Nicotine dependence is associated with poor sleep quality and shorter sleep duration among smokers.

Nicotine is a hygroscopic, colorless to yellow-brown, oily liquid, that is readily soluble in alcohol, ether or light petroleum. It is miscible with water in its neutral amine base form between 60°C and 210°C. It is a dibasic nitrogenous base, having K b1=1×10 −6, K b2=1×10 −11. [153] It readily forms ammonium salts with acids that are usually solid and water-soluble. Its flash point is 95°C and its auto-ignition temperature is 244°C. [154] Nicotine is readily volatile ( vapor pressure 5.5 Pa at 25°C) [153] On exposure to ultraviolet light or various oxidizing agents, nicotine is converted to nicotine oxide, nicotinic acid (niacin, vitamin B3), and methylamine.

[186] Nicotine is highly addictive. [18] [19] [20] Slow-release forms (gums and patches, when used correctly) are less addictive and aid in quitting. [21] [22] [23] [24] Animal research suggests that monoamine oxidase inhibitors present in tobacco smoke may enhance nicotine's addictive properties.

PMID 22003417. Withdrawal symptoms upon cessation of nicotine intake: Chronic nicotine use induces neuroadaptations in the brain's reward system that result in the development of nicotine dependence. Thus, nicotine-dependent smokers must continue nicotine intake to avoid distressing somatic and affective withdrawal symptoms. Newly abstinent smokers experience symptoms such as depressed mood, anxiety, irritability, difficulty concentrating, craving, bradycardia, insomnia, gastrointestinal discomfort, and weight gain (Shiffman and Jarvik, 1976; Hughes et al., 1991). Experimental animals, such as rats and mice, exhibit a nicotine withdrawal syndrome that, like the human syndrome, includes both somatic signs and a negative affective state (Watkins et al., 2000; Malin et al., 2006). The somatic signs of nicotine withdrawal include rearing, jumping, shakes, abdominal constrictions, chewing, scratching, and facial tremors. The negative affective state of nicotine withdrawal is characterized by decreased responsiveness to previously rewarding stimuli, a state called anhedonia.
