The long use of Fagerström Test for Nicotine Dependence is supported by the existence of significant preexisting research, and its conciseness.The 4th edition of the American Psychiatric Association Diagnostic and Statistical Manual of Mental Disorder (DSM-IV) had a nicotine dependence diagnosis which was defines as "...a cluster of cognitive, behavioral, and physiological symptoms..." In the updated DSM-5 there is no nicotine dependence diagnosis, but rather Tobacco Use Disorder, which is defined as, "A problematic pattern of tobacco use leading to clinically significant impairment or distress, as manifested by at least 2 of the following [11 symptoms], occurring within a 12-month period. "The Cigarette Dependence Scale was developed "to index dependence outcomes and not dependence mechanisms". The Nicotine Dependence Syndrome Scale, "a 19-item self-report measure, was developed as a multidimensional scale to assess nicotine dependence". The Wisconsin Inventory of Smoking Dependence Motives "is a 68-item measure developed to assess dependence as a motivational state". Mechanisms
Traditional cigarettes are the most common delivery device for nicotine. However, electronic cigarettes are becoming more popular. Nicotine can also be delivered via other tobacco products such as chewing tobacco, snus, pipe tobacco, hookah, all of which can produce nicotine dependence. Biomolecular
Pre-existing cognitive and mood disorders may influence the development and maintenance of nicotine dependence. Nicotine is a parasympathomimetic stimulant that binds to and activates nicotinic acetylcholine receptors in the brain, which subsequently causes the release of dopamine and other neurotransmitters, such as norepinephrine, acetylcholine, serotonin, gamma-aminobutyric acid, glutamate, endorphins, and several neuropeptides.
Common dependence assessment scales for cigarette smokers are the Fagerström Test for Nicotine Dependence, the Diagnostic and Statistical Manual of Mental Disorders, the Cigarette Dependence Scale, the Nicotine Dependence Syndrome Scale, and the Wisconsin Inventory of Smoking Dependence Motives (WISDM).Nicotine is a parasympathomimetic stimulant that attaches to nicotinic acetylcholine receptors in the brain. Neuroplasticity within the brains reward system, including an increase in the number of nicotine receptors, occurs as a result of long-term nicotine use, leading to nicotine dependence. There are genetic risk factors for developing dependence. For instance, genetic markers for a specific type of nicotinic receptor (the α5-α3-β4 nicotine receptors) have been linked to increased risk for dependence. Evidence-based treatments, including medications (nicotine replacement therapy, bupropion, varenicline, or cytisine) and behavioral counseling, can double or triple a smokers chances of quitting successfully. Definition
Nicotine dependence is defined as a neurobiological adaptation to repeated drug exposure that is manifested by highly controlled or compulsive use, the development of tolerance, experiencing withdrawal symptoms upon cessation including cravings, and an inability to quit despite harmful effects. Nicotine dependence has also been conceptualized as a chronic, relapsing disease. A 1988 Surgeon General report states, "Tolerance" is another aspect of drug addiction [dependence] whereby a given dose of a drug produces less effect or increasing doses are required to achieve a specified intensity of response. Physical dependence on the drug can also occur, and is characterized by a withdrawal syndrome that usually accompanies drug abstinence. After cessation of drug use, there is a strong tendency to relapse.
