“…Nonetheless, self-reported craving is a commonly used proxy and ecological momentary assessments acquired with real-time electronic diaries confirm that exposure to drug cues, and their elicitation of craving states, commonly occur in the minutes and hours before new bouts of stimulant drug use (Epstein et al, 2009). Similarly, in laboratory studies, craving and reward-seeking behavior have been reported to increase following exposure to cues associated with amphetamine (Culbertson et al, 2010; Tolivar et al, 2010), cocaine (Childress et al, 1988, 1993), alcohol (George et al, 2001; Bragulat et al, 2008), cigarettes (Droungas et al, 1995; Carter and Tiffany, 2001; Wray et al, 2011), heroin (Fatseas et al, 2011; Zhao et al, 2012a), and natural rewards such as food (Jansen, 1998; Kelley and Berridge, 2002; Mahler and de Wit, 2010) and sex (Conaglen and Evans, 2006; Kim and Zauberman, in press). …”
