  • Title: Smoking a virtual cigarette increases craving among smokers.
    Author: García-Rodríguez O, Weidberg S, Gutiérrez-Maldonado J, Secades-Villa R.
    Journal: Addict Behav; 2013 Oct; 38(10):2551-4. PubMed ID: 23793042.
    Abstract:
    Previous studies have shown the efficacy of virtual reality (VR) environments that reproduce smoking-related stimuli for increasing self-reported craving and psychophysiological reactivity in smokers. However, no study to date has attempted to simulate smoking behavior itself by means of VR technology. The aim of this study was to assess the effect of smoking a virtual cigarette on self-reported craving levels and heart rate (HR) in a sample of smokers. Participants were 45 smokers randomly assigned to three VR conditions built into a virtual pub: smoking a virtual cigarette, throwing virtual darts at a virtual dartboard or just being in the virtual pub. Results showed that smoking a virtual cigarette significantly increased self-reported craving and HR when compared to the other two conditions. These results reveal that simulation of smoking behavior in a VR environment functions as an efficacious proximal cue that can be used for triggering craving under the cue-exposure paradigm.
