Active clinical trials for "Substance-Related Disorders"

The purpose of this study is to compare the effectiveness of different levels of counseling (intensive outpatient versus standard outpatient) on treatment outcomes for African American adult patients receiving buprenorphine in 2 formerly "drug-free" programs.

This is a single site, double-blind, randomized, placebo-controlled, crossover study to assess the pharmacodynamics (PD) of RDC-0313 coadministered with buprenorphine in 12 healthy, opioid-experienced, non-treatment-seeking subjects.

Cannabis is the most used illicit substance in the United States. Previous studies suggest that atypical antipsychotics decrease the frequency and the amount of substance use in subjects with and without psychotic illness. So far, there are no controlled studies assessing the effectiveness of atypical antipsychotics for decreasing cannabis and other substance use in individuals with cannabis use disorders. The investigators postulate that the atypical antipsychotic quetiapine ER is an effective agent for improving substance use outcomes in subjects with cannabis use disorders. In this pilot study, the investigators will test this hypothesis in heavy cannabis users (i.e., individuals who are cannabis dependent and smoke three times or more per week). Because 50% of these heavy cannabis users report histories of psychotic experiences (i.e., attenuated positive symptoms) while smoking and are at risk for recurring psychotic symptoms, the investigators will focus this pilot clinical trial on this subgroup of cannabis users in order to increase the risk/benefit ratio of this study and target a population that may also benefit from the antipsychotic effect of quetiapine ER. Considering the lack of controlled studies assessing the efficacy of atypical antipsychotics in heavy cannabis users, assessing the effectiveness of an atypical antipsychotic medication on substance use and clinical outcomes in this population is critical for improving the prognosis of these individuals. Thus, the aims of this randomized, double-blind, placebo-controlled study are to assess the efficacy of an atypical antipsychotic (quetiapine ER) in 120 subjects with cannabis dependence, a recent history (within a year) of attenuated psychotic symptoms, and using cannabis 3 times or more per week for: (1) decreasing the use of cannabis and other substances; and (2) preventing the recurrence of psychotic experiences. The investigators will also assess the effects of quetiapine ER on craving and mood, and its tolerability. This project will be a 12-week, randomized, double-blind, placebo-controlled study with quetiapine ER and it will include a comprehensive assessment of symptoms, substance use, and side effects. This study will benefit the field by providing unique data on the relative efficacy and tolerability of treatment with atypical antipsychotics in heavy cannabis users with a vulnerability to psychosis. This study will be the basis for future studies assessing the long-term efficacy and tolerability of atypical antipsychotics in individuals with cannabis use disorders.

The purpose of the study is to determine whether interpersonal psychotherapy is effective for treating co-occurring depression and substance use among women prisoners.

The purpose of this study is to assess the acceptability and safety of Suboxone in heroin users as a replacement therapy for opioid dependency by comparing the clinical response of participants who are inducted directly onto Suboxone with that of participants who are inducted first to Subutex and then transferred to Suboxone.

The primary objective is to test the hypothesis that Quetiapine XR (Extended Release) monotherapy and adjunctive therapy is effective in the acute treatment of bipolar depression and comorbid generalized anxiety disorder in patients with bipolar disorder with or without a substance use disorder. The secondary aim is to generate an estimate of effect size to power a definitive large-scale, multi-site collaborative R01 and to configure the use of the primary and secondary outcome measures in the definitive large-scale study.

Two approaches for providing evidence-based substance abuse treatment (EBT), group motivational interviewing (GMI) and the In-Home-Messaging-Device (IHMD), are interventions that have the characteristic ability for increasing accessibility to evidence-based treatment among patients with substance use problems and are proposed for investigation. GMI is based on motivational interviewing, an intervention that has shown consistent significant effects in promoting treatment retention and reduced substance use among individuals with substance use disorders, and is delivered in a group format. IHMD is a user-friendly computerized Tele-mental Health communication tool that allows interaction through the telephone line between a Veteran and the health care provider in an individual's home or residential placement. The current proposal aims to determine whether GMI and IHMD lead to a significantly greater increase in treatment engagement and reduction in alcohol use compared to a treatment control condition (TCC) among Veterans with a substance use problem and a co-existing psychiatric disorder.

The objective of this study is to test whether screening and brief intervention for drug use among primary care patients leads to improved drug-related outcomes (such as decreased drug use and consequences).

Intimate partner violence is a significant societal problem. There is considerable evidence that a strong relationship between the use of alcohol and other drugs and intimate partner violence exists. Besides, a few studies indicate that reducing substance use may have a positive impact on IPV. Therefore, in this study, patients in substance abuse treatment for the use of alcohol, cannabis or cocaine who also admit to perpetrating intimate partner violence will be randomly assigned to either cognitive behavioral therapy addressing substance abuse combined with treatment for offenders of intimate partner violence or substance abuse treatment alone.

Background Smokers often reject drugs as smoking cessation aids. Nonpharmacological interventions are notoriously under-evaluated. Methods We conducted a randomized clinical trial in which we compared a medication, i.e., sustained-release bupropion (Zyban®; 413 subjects), at the time of the trial the most efficacious pharmacological smoking cessation aid, with an ultrashort psychotherapeutic intervention, Psychodynamic Model Training® (366 subjects), a manual-based psychodynamically oriented 1 ½ day autosuggestion training. Outcome criterion was 12-month self-reported continuous abstinence confirmed by urine cotinine levels below the level of detection (13 ng/ml) or, in an independent analysis, by exhaled carbon monoxide of 10 ppm or less at all interviews conducted at 3, 6, and 12 months.
