Neuroimaging and CBD for Opiod Use Disorder
Heroin AbuseOpioid Use Disorder2 moreThe investigators propose an imaging study to investigate the neurobiological effects of CBD (vs placebo) in participants with opioid use disorder who are maintained on methadone. The purpose of the study is to determine the neural circuits and transmitters associated with the effects of CBD on to reduce craving and anxiety. The neuroimaging will be conducted in participants immediately following their first administration of CBD (800mg or placebo) and one week after the last administration (3 daily doses). This CBD administration protocol was shown in previous studies by the investigators to reduce craving and anxiety in abstinent heroin users.
Mindfulness-Oriented Recovery Enhancement (MORE) in Heroin Addiction
Opiate Use DisorderIn this study, neuroimaging of reward processing, drug cue reactivity and inhibitory control is used before and immediately after 8 weeks of two types of group therapy in individuals with opioid addiction; clinical outcomes will be assessed before, immediately and three months after treatment. Results could point to factors that track and predict recovery with treatment, offering clinicians markers that can be used for enhancing precision medicine with the goal of reducing morbidity and mortality associated with opiate addiction.
Buprenorphine Stabilization and Induction Onto Vivitrol for Heroin-dependent Individuals
Heroin DependenceA short-term treatment with buprenorphine prior to initiating treatment with naltrexone may increase the proportion of heroin-dependent patients successfully inducted onto Vivitrol.
Extended-Release Naltrexone Opioid Treatment at Jail Re-Entry
Heroin DependenceOpioid-Related DisordersThe purpose of this study is to compare the effectiveness of extended-release naltrexone (XR-NTX) vs. enhanced treatment-as-usual (TAU) among opioid dependent adults leaving NYC jails. In parallel, we propose to recruit a matched, quasi-experimental methadone cohort, which will result in a naturalistic comparison of XR-NTX vs. an established jail-based methadone treatment program standard-of-care. Our primary aim is to compare time-to-relapse among participants treated with XR-NTX vs. randomized TAU controls and time-to-relapse among XR-NTX arm vs. jail-based MTP participants, following release from jail. Secondary aims will compare related opioid treatment outcomes post-release across all arms.
Effect of Clonidine on Responses to Imagery Scripts
Cocaine AbuseHeroin AbuseBackground: - 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.
Opiate Dependence: Combined Naltrexone/Behavior Therapy - 1
Heroin DependenceThe overall goal of this research project is to test a newly developed behavioral therapy to enhance the efficacy of naltrexone maintenance and make it a viable alternative to methadone maintenance or detoxification methods for treatment of opiate dependence. HYPOTHESES: Outpatient treatment with Behavioral Naltrexone Therapy will yield a lower rate of relapse to illicit opiates compared to naltrexone plus Compliance Enhancement (CE) Therapy. Lifetime history of depression will predict dysphoria and non-compliance with naltrexone.
Treatment of Opioid/Heroin Dependence: Comparison of Three Medication Dosing Regimens
Heroin DependenceOpioid-Related DisordersHeroin dependence remains a major addiction problem in the United States. The purpose of this study is to determine the effectiveness of levoacetyl methadol (ORLAAM) in treating heroin dependent individuals.
Addition of Naltrexone to Methadone Taper
Heroin DependenceOpioid-Related Disorders1 moreThere is a continuing search for more effective opiate detoxification treatments. This study's purpose is to investigate the effects of adding very low doses of naltrexone to a methadone tapering treatment in opioid dependent individuals.
Buprenorphine/Naloxone Versus Clonidine for Outpatient Opiate Detoxification - 1
Heroin DependenceMorphine Dependence1 moreThe purpose of this study is to assess buprenorphine/naloxone versus clonidine for outpatient opiate detoxification.
Effects of Dynorphin 1-13 on Heroin Addiction - 1
Opioid-Related DisordersSubstance Withdrawal SyndromeThe purpose of this study is to evaluate the effects of IV dynorphin in humans during acute heroin abstinence, in order to determine that dynorphin suppresses acute opiate withdrawal, reduces opiate craving, and is safe at doses required to produce the above effects.
