  • Title: Subjective dimensions of heroin urges: influence of heroin-related and affectively negative stimuli.
    Author: Sherman JE, Zinser MC, Sideroff SI, Baker TB.
    Journal: Addict Behav; 1989; 14(6):611-23. PubMed ID: 2618844.
    Abstract:
    Thirty-five male drug-free heroin addicts rated their affect, craving, and withdrawal in response to boring, anxiety-eliciting, and heroin stimuli. Results revealed that: (a) heroin cues were more effective than boring or anxiety-eliciting cues in prompting self-reports of craving or withdrawal; (b) heroin cues produced an affective state characterized by self-reported low-pleasure and high anxiety/tension; (c) craving was not correlated with any particular affective state, but rather was associated with a variety of negative affects--anxiety, depression, fatigue, anger; (d) the coherence (intercorrelations) of affective, craving, and withdrawal measures was greatest when addicts made their self-ratings immediately after exposure to drug stimuli; and (e) while addicts routinely reported craving without withdrawal sickness, they virtually never reported withdrawal sickness without reporting craving. These results suggested that the potential for negative reinforcement subserved stimulus elicited craving and that craving involved cognitive appraisal processes (attributions, expectations).
