Filter by:This randomized controlled trial examined whether an abbreviated treatment using abstinence contingency management for housing and work/training (CM, n=103) with cocaine dependent, non-psychotic, dually diagnosed homeless persons, would show non-inferior outcomes compared to the full treatment (CM+, n=103). It was hypothesized that CM+ would show superior abstinence and retention outcomes, but that CM, with components derived from previously effective behavioral day treatment, would obtain non-inferior outcomes, defined as 75% or more of those observed for the full treatment (CM+) during active treatment months 1-6. The CM+ included all CM components but added behavioral day treatment that included voucher reinforcement of $7.50-15.00, for objective weekly therapeutic goal attainment in five domains of functioning: drug dependence, homelessness, unemployment, non-drug related recreational activities, and behavioral, health, or mental health problems. Abstinence was assessed by observed urine specimen collection and weekly testing weeks 1-52, and randomly, bi-monthly for months 13-18. Abstinence, homelessness, employment and other outcomes were also assessed at baseline, 2, 6, 12, and 18 months.
The purpose of study is to determine if modafinil promotes cocaine abstinence and reduces high risk behavior in cocaine dependent subjects.
The purpose of this study is to test whether a cognitive behavioral therapy (CBT) and a medication called modafinil, which is approved to treat sleep disorders, will help individuals who are abusing cocaine.
This research study is being done to look at the safety of the medication Mirtazapine (Remeron) in people who have cocaine dependence and depression. Hypotheses I. Cocaine usage will be less in the mirtazapine treatment group (MG) than in the control group (CG). II. A greater increase in Clinician Global Impression (CGI) score will be observed in the MG than in the CG. Secondary Hypotheses: I. A greater decrease in Hamilton Rating Scale for Depression (HAM-D) and Hamilton Rating Scale for Anxiety (HAM-A) scores will be observed in the MG than in the CG. II. A greater decrease in HIV risk behaviors will be observed in the MG than in the CG. III. A greater improvement in sleep structure will be observed in the MG than in the CG. IV. The proportion of subjects experiencing severe adverse drug reactions that necessitate termination from the study by one of the study clinicians will not differ between the MG and CG. V. Retention will be greater in MG than in CG.
Background: - Research has shown that clonidine, a drug originally prescribed to treat high blood pressure and some symptoms of opioid withdrawal, can help block stress-induced relapse to heroin and cocaine seeking in rats. However, it does not seem to block cue-induced relapse in rats. Researchers are interested in studying whether clonidine shows the same pattern of effects on stress- and cue-induced cravings for heroin or cocaine in humans. Objectives: - To compare the ability of clonidine to reduce stress- and cue-induced cocaine and heroin craving in drug abusers. Eligibility: - Individuals between 18 and 55 years of age who are current cocaine or heroin users. Design: - This study will consist of two visits: a screening visit to determine eligibility and an experimental/script session. - Before the script session, participants will provide urine and breath samples for testing. Participants will complete questionnaires to measure their current drug craving and days since last use of cocaine or heroin. - At the start of the script session, participants will receive a dose of clonidine or placebo as directed by the study researchers. Three hours after dosing, participants will be read four scripts (two neutral, one stress-inducing, and one drug-cue-related) with breaks in between each script. After each script, participants will respond to questions about levels of stress and craving. - Participants will provide saliva samples immediately before and during the script readings, and will also be measured for skin response to the scripts.
The purpose of this study is to compare the effects of citalopram versus placebo given in the context of contingency management for cocaine dependence.
Background: - The treatment of addiction often hinges on preventing relapse into drug-using behaviors, which occurs at high rates even after prolonged abstinence. Research has shown that constant reporting through personal data-collection devices, such as electronic diaries, can help prevent relapse and reinforce abstinence. This constant reporting is known as Ecological Momentary Assessment (EMA). - The researchers here at NIDA have already completed two major arms of the study, focusing on patterns of craving and drug use during methadone maintenance, and on whether electronic diaries could help remind outpatients to complete treatment tasks. An ongoing arm of the study is examining connections among drug craving/use, stress, and geographical location. Objective: - To investigate the role of stress associated with geographical location in drug craving and use. Eligibility: - Individuals between 18 and 65 years of age or older who are dependent on opioids (cocaine and/or heroin). Design: - The study will last 28 weeks. After the initial screening, participants will receive daily methadone and weekly drug counseling sessions that will continue throughout the study. - After 3 weeks of methadone treatment, participants will have 15 weeks of EMA in which they will record both event-triggered cravings and daily responses (3 per day). EMA will consist of event-triggered recordings (initiated by participants whenever they use heroin or cocaine, or whenever they feel an urge to do so) and random-signal-triggered recordings (3 per day). During EMA, participants will begin a voucher-based program to encourage abstinence from heroin and cocaine. - Participants will also carry global positioning system (GPS) units to record their locations during these 15 weeks, and will complete questionnaires about stress levels at specific intervals during the study. - At the end of the study, participants will have the choice of transferring to a community clinic or undergoing an 8-week taper from methadone.
The primary goal of this study is to determine how contingency management can best be combined with standard or high doses of methadone to increase simultaneous abstinence from heroin and cocaine.
Background: - The treatment of addiction often hinges on preventing relapse into drug-using behaviors, which occurs at high rates even after prolonged abstinence. Some methadone patients continue to abuse cocaine and heroin during treatment, even with extensive psychosocial services. More research is needed to look at the results from earlier studies of continued drug use during methadone treatment, focusing on the results of fixed vs. flexible doses of methadone to reduce the likelihood of continued drug use and the role of monetary vouchers as an incentive to continue abstinence from illicit substances. Objectives: - To determine if the combination of flexible methadone dosing and voucher-based contingency management can improve rates of abstinence from heroin and cocaine. Eligibility: - Individuals between 18 and 65 years of age or older who are dependent on opioids (cocaine and/or heroin). Design: - The study will last 40 weeks. After the initial screening, participants will receive daily methadone and weekly drug counseling sessions that will continue throughout the study. - After 6 weeks of methadone treatment, participants who continue to use heroin and cocaine will be randomized to one of four groups for 16 weeks of study. Each group will receive a flexible or fixed dose of methadone, and one of two contingency management conditions. - Flexible-dose participants will receive individualized dose increases, based on drug use and withdrawal. Fixed-dose participants will be set at a specific dose of methadone that will not be changed. - The two contingency management conditions will be monetary vouchers given for regular cocaine-negative urine samples, or vouchers independent of urine cocaine screen results. - After the study phase, participants will have 10 weeks of standard individual counseling and stable doses of methadone. Urine samples will continue to be collected, but no vouchers will be given. - At the end of the study, participants will have the choice of transferring to a community clinic or undergoing a 10-week taper from methadone.
The purpose of this study is to determine if lamotrigine add-on therapy is associated with decreased cocaine craving and improvement in depressive symptom severity than placebo in a group of outpatients with bipolar disorder and cocaine dependence. Additionally, this study is examining whether lamotrigine add-on therapy is associated with decreased cocaine use and the improvement of manic symptom severity than placebo in a group of outpatients with bipolar disorder and cocaine dependence.
