“…In a recent review, we found people with psychosis had similar reasons for reducing substance use to those reported in the general population ( Rebgetz, Kavanagh, et al, 2015 ). Any differences in these reasons were related to the presence of the psychotic disorder (e.g.…”

“…Up to 80% of people with psychosis report cannabis use, which has been associated with a range of adverse psychological, social, and physical health outcomes ( Hjorthøj, Fohlmann, & Nordentoft, 2009 ; van der Meer, Velthorst, & Generic Risk and Outcome of Psychosis (GROUP) Investigators, 2015 ). Clinical trials of psychological treatments for cannabis use in people with psychosis have not consistently reported better outcomes than control conditions ( Hjorthøj et al, 2009 , Rebgetz et al, 2015 ). This indicates that some people with psychosis cease or reduce using cannabis with little or no related treatment ( Childs et al, 2011 , Lobbana et al, 2010 ).…”

However, only eight studies have examined the subjective experience of ceasing or reducing cannabis among individuals with psychosis ( Rebgetz et al, 2015 , Rebgetz et al, 2015 ), and there is little examination of mechanisms underpinning the phenomenon.…”

IntroductionThere is growing evidence for natural recovery from cannabis use by people with psychosis, but mechanisms underpinning it need further exploration. This study prospectively explored this issue.MethodTwenty-two people with psychosis and cannabis misuse were recruited: 19 provided data for at least one follow-up assessment, and 13 of these (68%) reduced or ceased using cannabis. A semi-structured interview with the latter group explored reasons for initiating the attempt, strategies they employed, and context/s where any relapse occurred. Interpretative phenomenological analysis was used to identify themes.ResultsParticipants who reduced or ceased cannabis use had fewer negative symptoms at Baseline, and were more likely to only use cannabis. Major reasons for starting an attempt were worsening mental health, relationship and lifestyle difficulties. Effective strategies fell into psychological, relationship, lifestyle and medication themes. Only three participants reported a relapse: triggers involved substance-using peers, relationship difficulties, and problems with negative emotions including ones from past trauma.ConclusionsAn encouragingly high rate of maintained reductions in cannabis use was seen. Increased awareness of the benefits across multiple life domains from addressing cannabis use may be critical to the initiation and maintenance of attempts, both to maximise motivation, and avoid over-dependence on improvements in any single domain. Negative symptoms, multiple substance use, dysphoria and pressure from substance-using peers clearly offer additional challenges for control.

Objective: Comorbidity of psychotic disorder and substance use disorder is common. Studies demonstrate that this comorbidity constitutes a major mental health problem. The aim of this study is to investigate sociodemographic and clinical differences between illicit drug users and non-users in hospitalised male patients diagnosed with psychotic disorder. Method: This was a retrospective study evaluating files of 237 inpatients treated between January 2013 and December 2016 in Ege University Department of Psychiatry Male Inpatient Unit with diagnosis of Schizophrenia Spectrum and Other Psychotic Disorders according to DSM-5. Results: Of 237 participants, 16% had a lifetime use of an illicit drug. Participants with substance use disorder had a smaller mean age and shorter duration of education than participants without substance use disorder. Of all the participants with a history of substance use, 76.3% had a history of substance use in the first episode of psychosis. The most preferred substance in 72.4% of the participants with substance use during the first psychotic episode and in 68.4% of all the participants with substance use was cannabis. Treatment compliance was worse in the participants with substance use. Discussion: Our findings show that, when psychotic disorder is comorbid with substance use disorder, age of onset of psychotic symptoms decreases, duration of education shortens and treatment compliance deteriorates. These results should be supported by longitudinal studies using quantitative analysis methods.

-Background and Objectives:Cannabis use is common in early psychosis and has been linked to adverse outcomes. However, factors that influence and maintain change in cannabis use in this population are poorly understood. An existing prospective dataset was used to predict abstinence from cannabis use over the 6 months following inpatient admission for early psychosis.Methods: Participants were 67 inpatients with early psychosis who had used cannabis in the 6 weeks prior to admission. Current diagnoses of psychotic and substance use disorders were confirmed using a clinical checklist and structured diagnostic interview. Measures of clinical, substance use and social and occupational functioning were administered at baseline and at least fortnightly over the 6-month follow up.Results: No substance use or clinical variables were associated with 6-months' of cannabis abstinence. Only Caucasian ethnicity, living in private accommodation and receiving an income before the admission were predictive. Only private accommodation and receiving an income were significant predictors of abstinence when these variables were entered into a multivariate analysis.Conclusions: While the observed relationships do not necessarily imply causation, they suggest that more optimal substance use outcomes could be achieved by addressing the accommodation and employment needs of patients.
