Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Theoretical Framework: Cigarette smoking is the leading preventable cause of death worldwide, with nicotine dependence notably common among individuals with Substance Use Disorders (SUD). Smoking exacerbates both physical and mental health issues, further complicating the treatment of SUD. Current therapeutic approaches for SUD often prove inadequate, indicating a need for new strategies. Recent advancements in metabolomics and gut microbiome research have provided valuable insights into the biological mechanisms underlying addiction.

Objectives: This study aims to investigate the therapeutic potential of smoking cessation for individuals with SUD, using a six-week intervention within a therapeutic community. The research specifically explores the psychobehavioral, metabolic, and gut microbiome domains. It is hypothesized that smoking cessation will improve emotional regulation, self-efficacy, and reduce substance craving, mediated by changes in metabolic and microbiome profiles linked to brain reward systems.

Methods: A randomized controlled trial (N=100) will be conducted, examining outcomes such as clinical relapse rates, microbial and metabolic markers, particularly in choline and folate metabolism. Participants will undergo a six-week smoking cessation intervention, with pre- and post-assessments, compared to a control group receiving treatment as usual. Metabolomic and microbiome analyses will be conducted using blood and stool samples, alongside psychological assessments via questionnaires. Assessments on a behavioural level will take place at a 3-months follow-up.

Study Groups

Treatment As Usual

Patients in the TAU group receive long-term rehabilitation drug treatment according to the 'community as a treatment'-model

Group Type ACTIVE_COMPARATOR

Long-term drug therapy within a therapeutic community

Intervention Type BEHAVIORAL

The standard treatment within the 'Grüner Kreis' therapeutic community - which all participants will receive - consists of group therapy (once a week), individual psychotherapy (once a week), counselling by social workers, psychiatric consultations, as well as sport-, art- and work-therapy. Daily life is organized according to principles of therapeutic community-based addiction treatment.

6-weeks smoking cessation cognitive-behavioral therapy intervention

The "smoke free in 6 weeks" program is a standardized behavioural therapy intervention that takes place once a week for 1.5 hours over 6 weeks and is provided by the Austrian health insurance provider Österreichische Gesundheitskasse (ÖGK).

Group Type EXPERIMENTAL

6-weeks CBT smoking cessation programme

Intervention Type BEHAVIORAL

Held in the therapeutic community, the intervention will employ principles of cognitive-behavioural therapy (CBT) coupled with personalized recommendations for nicotine replacement. The Austrian Health Insurance standard for therapy will be guiding the program's content, which is tailored for inpatient clients. Specifically, the following interventions based on CBT techniques will be applied in the weekly group sessions consisting of 10 to 15 participants: Psychoeducation including information on tobacco addiction, health risks, advice on relapse prevention and the handling of craving, motivation building, behavioural observation.
