Orexin A gene expression was statistically significantly correlated with the Satisfaction with Life Scale (r = -0.28, p = 0.018), a visual analogue scale of craving (r = 0.734, p = 0.000) and three subscales of the World Health Organization Alcohol, Smoking and Substance Involvement Screening Test, i.e. nicotine consumption (r = 0.388, p = 0.001), alcohol consumption (r = 0.354, p = 0.002) and cannabis consumption (r = 0.783, p = 0.000).
