AB Cocaine use could be modulated by drug expectancies based on previously experienced subjectiveeffects. Some patients perceive a paradoxical calming effect after cocaine use. This study wasperformed to explore cocaine effect expectancies in patients diagnosed with cocaine use disorder,with and without co-occurring adult attention deficit hyperactivity disorder (ADHD). Secondly, wesought to empirically determine the presence of this paradoxical calming effect after cocaine use inpatients with co-occurring adult ADHD to identify the individuals most at risk of cocaine use andrelapse. Cross-sectional study using a consecutive sampling method of patients diagnosed withcocaine use disorder (n = 221) treated at public therapeutic communities in Andalusia (Spain).Participants completed a battery of instruments to assess the following variables: cocaine effectexpectancies, paradoxical calming effect, adult ADHD, and other co-occurring psychiatric disorders.A multivariate binary logistic regression analysis showed that two variables, the paradoxical calmingeffect and antisocial personality disorder (ASPD), were independently associated with theprobability of being diagnosed with adult ADHD (OR = 3.43, 95% CI = 1.88–6.26 and OR = 3.42,95% CI = 1.30–8.95, respectively). The presence of a paradoxical calming reaction to cocaine and/ora diagnosis of ASPD in patients with cocaine use disorder increases the diagnostic suspicion of cooccurring adult ADHD.
