Cocaine is the 2nd most used illicit substance in Europe and its use implies numerous health complications as well as an annual social cost of 8.7 G d'€. Classical (picture, video, audio, imagery based or in vivo) cue exposure therapy for substance craving (CET), i.e. the irrepressible and non-voluntary desire to use the substance, failed to prove efficacious in treating substance use disorder. Virtual reality cue exposure therapy for substance craving (VRCET), is more immersive, realistic and controllable, and is suggested as being a more efficacious intervention in reducing craving as compared to classical CET.
So far it's still not known, thus the secondary aim of the present randomized and clinical trial is to investigate, whether virtual reality cue exposure is more efficacious, as compared to classical cue exposure, in both eliciting and reducing cocaine craving in a clinical context of CET for cocaine craving. The main study aim to is to investigate whether a VRCET for cocaine craving based cognitivo-behavioral therapy (i.e. VRCET followed by memory focused cognitive therapy) is more efficacious than a behavioural therapy (i.e. classical exposure therapy to craving) in reducing cocaine craving.
To do so, 54 voluntary residential patients in treatment for cocaine use disorder will be recruited from the Universitary Hospital Center of Martinique (CHUM, Martinique, France) and Saint-Esprit Hospital Center (CHSE, Martinique, France) and randomly allocated in either a 3 weeks individual experimental treatment (10 meetings of VRET for cocaine craving followed by 5 meetings of memory focused cognitive therapy) or a 3 weeks individual control treatment (15 meetings of pictures based exposure therapy for cocaine craving). Self-reported measures of retrospective (last 14 days) and in virtuo exposure cocaine craving will be collected at the beginning, after 10 days, after 15 days of treatment and 1 month post. Others secondary subjective, urinary and physiological cocaine use related measures will also be collected.

| Virtual Reality Cue Exposure (VRCE) Therapy for Cocaine Craving - 2 weeks | Behavioral | 40 10 mins VRCEs for cocaine craving (desensitization to only cocaine craving cues; no others interventions). 4 VRCE and 2 different VRCE situations by meeting. Same VRCE situations spaced intra (30 mins) and inter meetings (48 hrs). 5 standard VRCE situations (appearance and dialogues adapted to Martinique field) varying from "only peers cocaine use talk" to "peers and participant prepare and use cocaine" and ranging from the lowest to the highest participant related cocaine craving level.
