Defining and Assessing Nicotine Dependence in Humans

West, Robert·2006·Novartis Foundation Symposia

Abstract

‘Addiction’ and ‘dependence’ are used synonymously by most researchers and defined as a reward-seeking (usually drug taking) behaviour that has become out of control. The diagnosis has been based on the alcohol dependence syndrome identified 30 years ago by Edwards and Gross and includes tolerance, craving, withdrawal symptoms, difficulty controlling use, important activities given up, and continuation despite harmful consequences. A substantial proportion of smokers are addicted by reference to these criteria. However, it is possible to improve on both the definition and its assessment. This paper proposes that addiction is more usefully regarded as a symptom of potentially a range of underlying pathologies involving the ‘motivational system’. Even among smokers there is heterogeneity in the pathology that makes it difficult for them to abstain voluntarily and this has important implications for treatment. For example, there will be smokers for whom the pathology involves a largely reversible effect of nicotine in creating an ‘acquired drive’, others for whom nicotine has induced long-term changes that make life less comfortable in its absence, and others whose smoking is more situationally driven. Assessment of addiction should first quantify the degree to which the behaviour dominates the individual's repertoire and then assess the underlying pathology in the motivational system. A framework for doing this is discussed.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The strength of nicotine hunger can be usefully assessed by recording how soon after waking the smoker first lights up a cigarette.

    “The strength of this can be usefully assessed by recording how soon after waking the smoker first lights up a cigarette (17,18).”
  • Wanting to smoke (enjoyment of smoking) deters quit attempts while needing to smoke (anticipated relief from nicotine hunger) and cue-driven impulses to smoke (experienced as 'urges') lead to relapse after the quit attempt has been started.

    “There is evidence emerging that wanting to smoke (enjoyment of smoking) deters quit attempts while needing to smoke (anticipated relief from nicotine hunger) and cue driven impulses to smoke (experienced as 'urges') lead to relapse after the quit attempt has been started (18,24).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
