A specific cognitive behavioral group therapy program for stimulant use disorder.

Introduction: Stimulant use is an important health issue. In the US in 2018, 2.8% of males and 1.

The clinical course of comorbid substance use disorder and attention deficit/hyperactivity disorder: protocol and clinical characteristics of the INCAS study.

Background: Substance use disorders (SUD) often co-occur with attention deficit hyperactivity disorder (ADHD). Although the short-term effects of some specific interventions have been investigated in randomized clinical trials, little is known about the long-term clinical course of treatment-seeking SUD patients with comorbid ADHD.

Aims: This paper presents the protocol and baseline clinical characteristics of the International Naturalistic Cohort Study of ADHD and SUD (INCAS) designed and conducted by the International Collaboration on ADHD and Substance Abuse (ICASA) foundation.

Feasibility of an Extensive Strategy for Adult Diagnosis of Attention Deficit Hyperactivity Disorder Among Patients Suffering From Substance Use Disorders.

Introduction: Attention Deficit Hyperactivity Disorder (ADHD) is found in up to 20% adults with Substance Use Disorder (SUD). ADHD + SUD is associated with a more complex clinical presentation and poorer outcomes than each disorder alone. In the presence of SUD, adult ADHD is particularly difficult to diagnose as both disorders can mimic or hide the symptoms of each other.

Occurrence and severity of cocaine-induced hallucinations: Two distinct phenotypes with shared clinical factors but specific genetic risk factors.

Unlabelled: Cocaine-induced transient hallucinations (CIH) are a frequent complication following cocaine intake that is associated with addiction severity.

Methods: Two hundred and forty-two non-psychotic and Caucasian lifetime cocaine users were included in a French multicentric study. Clinical variables and dopamine pathway genotype data were extracted and tested with CIH scores using a zero-inflated binomial model, which allows for the exploration of factors associated with occurrence and severity separately.

Risk and Protective Factors of Lifetime Cocaine-Associated Chest Pain.

Cocaine users often present with repetitive events of cocaine-associated chest pain (CACP), clinically resembling acute coronary syndromes. The aim of the study is to describe the specific risk factors for CACP. Cocaine users ( = 316) were recruited for a multicenter cross-sectional study.

Network analysis of psychotic manifestations among cocaine users.

Psychotic experiences can be described along a continuum ranging from no psychotic experience at all, to clinical psychotic disorder. Any individual in the general population may encounter psychotic experiences under certain circumstances. Transient Cocaine Induced Psychotic Symptoms (TCIPS) are a well described model of such circumstances.

Chronic exposure to cocaine is associated with persistent behavioral disturbances. A cross-sectional dimensional study in outpatients with multiple substance use disorders.

Rationale: Behavioral disturbances (BD) are prevalent in patients with substance use disorders (SUD).

Objectives: To test the hypothesis that chronic exposure to cocaine could favor the acquisition of BD that were not present in childhood.

Methods: We used child and adult ADHD self-report screening scales (WURS-25 and ASRS-6, respectively, with their usual threshold) as assessment tools for significant BD.

Relevance of treated cocaine users' retrospective memory of first cocaine use.

Little is known regarding between-subject variability in the subjective effects of first cocaine use. This study retrospectively assesses the subjective effects of first cocaine use in 160 current treatment-seeking cocaine use disorder patients. Subjective effects of first cocaine use were evaluated with an ad-hoc questionnaire used for cannabis effects.

Anxiety disorders are associated with early onset of heroin use and rapid transition to dependence in methadone maintained patients.

Early onset of heroin use is a severity marker of heroin use disorder. We studied the interaction between early onset and rapid transition to heroin dependence recorded with retrospective interviews in 213 patients with severe heroin dependence and history of methadone maintenance treatment. General linear models were used to identify independent factors associated with early onset, factors associated with rapid transition to dependence, and a multivariate model was used to study the interaction of those two dimensions.

Self-reported cue-induced physical symptoms of craving as an indicator of cocaine dependence.

Background: The presence of cocaine dependence is under-recognized by cocaine users and requires a careful standardized interview to be ascertained by clinicians.

Objective: To test if past experiences of cue-induced physical symptoms of craving (nausea, vomiting, sweating, shaking, nervousness) before cocaine use could be a useful way to boost the diagnosis of cocaine dependence.

Methods: A cross-sectional study of 221 cocaine users from several outpatient addiction treatment services in France, addressing the most severe period of cocaine use.

Childhood trauma are not associated with the intensity of transient cocaine induced psychotic symptoms.

A personal history of childhood trauma has been associated with the severity of psychotic symptoms in several disorders. We evaluated retrospectively cocaine-induced psychotic symptoms with the SAPS-CIP and childhood trauma with the CTQ in a clinical sample of 144 cocaine users. The SAPS-CIP score was not statistically associated with the presence or number or intensity of trauma, but was associated with rapid routes of administration (intravenous and smoked) and with frequent cocaine use.
