18 Clinical Trials for Various Conditions
More US residents are dependent on marijuana than on any other illicit drug, and the number enrolled in treatment for marijuana continues to increase such that it is now comparable to that for cocaine and heroin. This application seeks to advance the overarching goal to develop and disseminate cost-effective treatments for marijuana dependence that can address this growing problem. The researchers' previous research suggests that an intervention comprising motivational enhancement, cognitive-behavioral, and contingency-management components (MET/CBT/CM) produces greater rates of successful and durable outcomes than has been demonstrated previously. However, three issues relevant to its efficacy and eventual dissemination must be confronted. First, the outcomes achieved can only be characterized as modest; many individuals do not respond to the treatment and relapse rates remain problematic. Second, access is limited by the availability of trained providers. Third, the cost of delivering the treatment is higher than more traditional outpatient interventions. To address these issues, Specific Aim 1 is to develop and test a computer-assisted version of MET/CBT/CM. Computerized treatments have the potential to increase overall effectiveness of treatment services by increasing availability of and access to potent treatments, and by applying innovative technology to enhance outcomes. During Year 1, the intervention will be developed and pilot tested. An interactive program that showed promise in a previous trial for opioid dependence will be modified and enhanced to deliver individualized MET/CBT/CM using effective computer learning technologies. These technologies and access to the MET/CBT/CM program made available via the Internet between treatment sessions and after treatment ends have the potential to promote better learning and more use of coping skills, which in turn can improve outcomes. During Years 2-4 a randomized trial will provide an initial efficacy test of cMET/CBT/CM by comparing it with a brief treatment (MET) and with therapist-delivered MET/CBT/CM. Specific Aim 2 is to learn more about how behavioral treatments like MET/CBT/CM work by focusing on two putative mechanisms of action examined in prior trials: self-efficacy/coping skills and impulsivity/delay discounting. The experimental design will provide a unique opportunity to explore such mechanisms in a novel context- where the therapist is vs. is not a prominent part of the treatment. The proposed project will address the objectives of NIDA's Behavioral and Integrative Treatment Development Program by providing research on technology-assisted treatment that attempts to make treatment delivery less complex, easier to access, and less costly - while retaining or improving its effectiveness. Findings will inform future studies designed to refine the technology and how it is applied; conduct more definitive effectiveness testing; test generality to other populations including adolescents; and to further advance translation to community settings.
The aim of the study is to determine if atomoxetine treatment combined with motivational enhancement therapy is effective in reducing marijuana use in adult individuals with attention-deficit hyperactivity disorder and marijuana dependence.
The purpose of this study is to determine if buspirone combined with motivational enhancement therapy is effective in reducing marijuana use in marijuana-dependent adults.
This study will assess the effectiveness of a combination of buspirone and motivational interviewing therapy in the treatment of marijuana dependence.
The purpose of the study is to determine why and how marijuana users stop or reduce their marijuana use.
Recent research has identified the following withdrawal symptoms to be associated with abruptly stopping marijuana use: anxiety, irritability, bodily aches and pains, and difficulty sleeping. These symptoms resemble those of both depression and nicotine withdrawal, suggesting that a similar treatment drug may be useful. This study will evaluate the effectiveness of two antidepressant drugs, bupropion and nefazodone, in reducing withdrawal symptoms in marijuana dependent individuals.
The purpose of this study is to determine if dronabinol decreases the symptoms of marijuana addiction and withdrawal.
The primary objective of this application is to test the neurobehavioral mechanisms and effects of aprepitant as a new cessation agent for cannabis, tobacco or both.
Marijuana use is a major problem among veterans and non-veterans. A patient's use of marijuana while engaged in psychotherapy treatment may affect their memory and, therefore, limit their ability to benefit from treatment. This study is designed to test a new pharmacotherapy, modafinil, which has the potential to improve memory functioning in marijuana using individuals. We hypothesize that modafinil treatment will decrease ratings of drug liking and improve cognitive measures, especially episodic memory.
The purpose of this study is to determine if Venlafaxine Extended Release (Ven-XR) is effective in treating individuals with marijuana addiction and depression.
The purpose of this study is to evaluate the impact of treating depression on substance dependent teens.
The purpose of the project is to improve adolescent behavioral counseling services in healthcare settings with a new Internet/Intranet-based Motivational Enhancement Therapy (iMET) intervention that targets the use of tobacco, alcohol, and other drugs.
This project tests the feasibility and utility of a novel, integrated approach to treatment of patients with cannabis use disorder (CUD) and anxiety disorders.
Background: - Marijuana is the most widely used illicit drug in the world, yet relatively little is known about users who try to quit without formal treatment ( spontaneous quitting). Studies have suggested that there are some common strategies that many individuals use in spontaneous quitting, such as changing one s lifestyle or identity, reminding oneself of negative consequences, support from family and friends, and religion. However, more research is needed to determine potential treatment strategies for marijuana use. Objectives: * To identify strategies used to help with marijuana quitting among non-treatment seeking adult marijuana users. * To identify withdrawal symptoms experienced during marijuana quitting and their relationship to the quitting strategies used and the outcome of the quit attempt. * To evaluate whether subgroups of marijuana users differ in their experience of marijuana quitting. Eligibility: - Individuals at least 18 years of age who have made at least one attempt to quit marijuana use. Design: * The study will consist of one visit of approximately 1 to 2 hours. * Participants will fill out three questionnaires. The questionnaires have different types of questions, and will ask about background and lifestyle, marijuana use and craving patterns and behaviors, and difficulties in previous attempts to quit using marijuana.
The purpose of this study is to evaluate how people who frequently use marijuana respond to a stressful task, and if a medication (oxytocin) affects this response.
Adolescents who are diagnosed with major depressive disorder are often also diagnosed with marijuana dependence. Fluoxetine is an antidepressant medication currently used to treat young people who are diagnosed with major depressive disorder. The purpose of this study is to determine the effectiveness of fluoxetine in treating adolescents and young adults diagnosed with both major depressive disorder and marijuana dependence.
The purpose of this study is to examine the impact of a medication called oxytocin on marijuana use and therapy response in people who frequently use marijuana.
Cognitive-behavioral coping skills therapy (CBT) is a widely used and recognized treatment that has been empirically validated for a range of substance use disorders, often with emergent effects and continuing improvement even after treatment ends. Treatment retention and compliance are associated with enhanced treatment outcomes in CBT. Contingency management (CM) also has very strong support and is associated with rapid, robust effects on targeted outcomes. Despite their many strengths, neither CBT nor CM is universally effective. It is now essential to seek strategies to maximize and extend the effectiveness of these two approaches and to better understand how these treatments exert their effects.
