Nicotine Use Disorder
The symptoms of Nicotine Withdrawal overlap with those of other substance withdrawal syndromes; Caffeine Intoxication; Anxiety, Mood, and Sleep Disorders; and medication-induced akathisia. Admission to smoke-free inpatient units can induce withdrawal symptoms that might mimic, intensify, or disguise other diagnoses. Reduction of symptoms associated with the resumption of smoking or nicotine-replacement therapy confirms the diagnosis.
Because regular nicotine use does not appear to impair mental functioning, Nicotine dependence is not readily confused with other Substance-Related Disorders and mental disorders.
