A smoker’s degree of tobacco dependence may be assessed by a range of measures. These include the frequency and quantity of tobacco consumed, biochemical markers (such as levels of cotinine, a by-product of nicotine metabolism, in the saliva), and questionnaire measures of self-reported smoking behaviour.1
Instruments used in clinical settings that assess whether a smoker satisfies the criteria for drug dependence include the DSM-5 criteria, derived from the Diagnostic and Statistical Manual of Mental Disorders of the American Psychiatric Association2 and the ICD-10 classification from the International statistical classification of diseases of the World Health Organisation3 A summary of the diagnostic criteria of Tobacco Use Disorder is described in Section 6.1.
Tests of psychological and physiological dependence, in the form of a questionnaire for smokers,4 include the Fagerström Test for Nicotine Dependence5 (which evolved from the earlier Fagerström Tolerance Questionnaire6), the Cigarette Dependence Scales,7 the Nicotine Dependence Syndrome Scale,8 the Wisconsin Inventory of Smoking Dependence Motives,9 and the Autonomy over Tobacco Scale10
The most commonly used measure11 is the Fagerström Test for Nicotine Dependence.5, 12 This instrument asks the smoker a set of questions, the answers to which are scored as shown in Table 6.5.1 and added to give a total score: a score of six or more is seen as an indicator of high dependence.

Another, newer measure of levels of addiction is the ‘Hooked on Nicotine Checklist,’ or HONC, which assesses when the individual loses their control, or autonomy, over their use of tobacco use.13 Loss of autonomy is the point at which ‘the sequelae of tobacco use, either physical or psychological, present a barrier to quitting’ (p399).13 The HONC was originally devised for use with younger smokers for whom some of the questions in the Fagerström Test were much less relevant. For example, most adolescents would not be able to smoke within minutes of waking in the morning, or if ill in bed, unless they were doing so with parental permission.13 Subsequent research suggests that the HONC is also useful for measuring loss of autonomy over smoking in adults.14, 15
The HONC asks 10 questions to assess degree of tobacco dependence.13, 16
1. Have you ever tried to quit, but couldn’t?
2. Do you smoke now because it is really hard to quit?
3. Have you ever felt like you were addicted to tobacco?
4. Do you ever have strong cravings to smoke?
5. Have you ever felt like you really needed a cigarette?
6. Is it hard to keep from smoking in places where you are not supposed to, like school?
When you tried to stop smoking … (or, when you haven’t used tobacco for a while…)
7. Did you find it hard to concentrate because you couldn’t smoke?
8. Did you feel more irritable because you couldn’t smoke?
9. Did you feel a strong need or urge to smoke?
10. Did you feel nervous, restless, or anxious because you couldn’t smoke?
Research on the HONC in young people has found that dependence may develop rapidly, even at low, sporadic levels of consumption.13 Some of these findings are discussed in Section 6.13.
