what are the body's physical and psychological responses to a lack of nicotine called?
nicotine withdrawal
the health effects of long-term nicotine use is unknown. it may be decades before the long-term health effects of nicotine vapor inhalation is known. it is not recommended for non-smokers. public health authorities do not recommend nicotine use for non-smokers. the pureness of the nicotine differs by grade and producer. the impurities associated with nicotine are not as toxic as nicotine. the health effects of vaping tobacco alkaloids that stem from nicotine impurities in e-liquids is not known. nicotine affects practically every cell in the body. the complex effects of nicotine are not entirely understood. it poses several health risks. short-term nicotine use excites the autonomic ganglia nerves and autonomic nerves, but chronic use seems to induce negative effects on endothelial cells. nicotine may have a profound impact on sleep. the effects on sleep vary after being intoxicated, during withdrawal, and from long-term use. nicotine may result in arousal and wakefulness, mainly via incitement in the basal forebrain. nicotine withdrawal, after abstaining from nicotine use in non-smokers, was linked with longer overall length of sleep and rem rebound. a 2016 review states that "although smokers say they smoke to control stress, studies show a significant increase in cortisol concentrations in daily smokers compared with occasional smokers or nonsmokers. these findings suggest that, despite the subjective effects, smoking may actually worsen the negative emotional states. the effects of nicotine on the sleep-wake cycle through nicotine receptors may have a functional significance. nicotine receptor stimulation promotes wake time and reduces both total sleep time and rapid eye movement sleep."

nicotine, a key ingredient in most e-liquids, is a highly addictive substance, on a level comparable to heroin and cocaine. addiction is believed to be a disorder of experience-dependent brain plasticity. the reinforcing effects of nicotine play a significant role in the beginning and continuing use of the drug. first-time nicotine users develop a dependence about 32% of the time. chronic nicotine use involves both psychological and physical dependence. nicotine-containing e-cigarette vapor induces addiction-related neurochemical, physiological and behavioral changes. nicotine affects neurological, neuromuscular, cardiovascular, respiratory, immunological and gastrointestinal systems. neuroplasticity within the brain's reward system occurs as a result of long-term nicotine use, leading to nicotine dependence. the neurophysiological activities that are the basis of nicotine dependence are intricate. it includes genetic components, age, gender, and the environment. pre-existing cognitive and mood disorders may influence the development and maintenance of nicotine dependence. nicotine addiction is a disorder which alters different neural systems such as dopaminergic, glutamatergic, gabaergic, serotoninergic, that take part in reacting to nicotine. long-term nicotine use affects a broad range of genes associated with neurotransmission, signal transduction, and synaptic architecture. the most well-known hereditary influence related to nicotine dependence is a mutation at rs16969968 in the nicotinic acetylcholine receptor "chrna5", resulting in an amino acid alteration from aspartic acid to asparagine. the single-nucleotide polymorphisms (snps) rs6474413 and rs10958726 in "chrnb3" are highly correlated with nicotine dependence. many other known variants within the "chrnb3–chrna6" nicotinic acetylcholine receptors are also correlated with nicotine dependence in certain ethnic groups. there is a relationship between "chrna5"-"chrna3"-"chrnb4" nicotinic acetylcholine receptors and complete smoking cessation. increasing evidence indicates that the genetic variant "chrna5" predicts the response to smoking cessation medicine. the ability to quitting smoking is affected by genetic factors, including genetically based differences in the way nicotine is metabolized. in the "cyp450" system there are 173 genetic variants, which impacts how quickly nicotine is metabolizes by each individual. the speed of metabolism impacts the regularity and quantity of nicotine used. for instance, in people who metabolize nicotine gradually their central nervous system effects of nicotine lasts longer, increasing their probability of dependence, but also increasing ability with quitting smoking.
