Filter by:The purpose of this study is to if a brief motivational intervention, compared to health education sessions, reduces alcohol and marijuana use and is related to fewer sexually transmitted infections (STI)in emerging adults who are engaging in alcohol and marijuana use.
The purpose of this study is to determine whether guanfacine represents a tolerable, potentially effective pharmacotherapy option for cannabis dependence. Interested in seeing whether guanfacine treatment reduces marijuana consumption, withdrawal symptoms, and craving as compared to baseline.
The purpose of this 3-year trial is to test the efficacy of transdermal nicotine patch versus placebo patch on marijuana withdrawal symptoms in cannabis-dependent individuals, using a randomized, double-blind, and placebo-controlled design. This proposal is in response to RFA-DA-10-016(R01) Medications Development for Cannabis-Related Disorders. Consistent with the goals of this RFA, the overall goal of the proposed project is to assess the impact of transdermal nicotine patch (TNP) on marijuana (MJ) withdrawal (negative affect and craving motivated by negative affect) symptoms in MJ-dependent individuals.
Study participants received dronabinol (0, 120mg/day and 240mg/day) for 12 consecutive days in a randomized order. During each dronabinol maintenance period they were able to self-administer active or placebo cannabis using either a progressive ratio schedule or choice between cannabis and monetary alternative.
Cannabis use disorders are an important public health problem in the United States, but there are no effective medications available to treat these disorders. The investigators intend to test a medication with interesting properties, nabilone, as a treatment for cannabis dependence and to study the relationship of this treatment with the brain using functional MRI brain scans. Nabilone and marijuana have similar effects upon behaviors and the human body, suggesting that nabilone may decrease cannabis withdrawal symptoms while allowing treatment-seeking patients to benefit from behavioral treatments when they are trying to stop using cannabis. The investigators propose to assess the relationship of nabilone, when added to behavioral treatment, on cannabis use patterns in cannabis-dependent patients. The investigators also aim to determine the effects of nabilone on performance on neuropsychological tests and to assess the correlation of neuropsychological performance to brain changes using functional MRI brain scans. The investigators hypothesize that patients receiving nabilone will reduce their use of cannabis more than patients receiving placebo during this 10-week treatment trial.
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.
The investigators are conducting a Stage 1 pilot feasibility study at McLean Hospital to develop and refine a Cognitive Behavioral Therapy (CBT) intervention. The investigators aim to develop a feasible 10-week integrated CBT intervention for the treatment of concurrent marijuana dependence and nicotine dependence. The investigators hypothesize that the CBT intervention, in conjunction with Nicotine Replacement Therapy (NRT) in the form of a transdermal nicotine patch, will reduce the use of marijuana and nicotine.
This study will integrate and adapt a cognitive remediation (Cognitive Enhancement Therapy [CET]) and an affect regulation (Personal Therapy [PT]) intervention for 50 individuals with schizophrenia that misuse cannabis. Participants will be randomized to CET/PT plus treatment as usual (TAU) or TAU alone and treated for 18 months.
Background: - Individuals with schizophrenia or schizoaffective disorders have a high prevalence of cannabis use. Understanding some of the environmental factors that maintain cannabis use, such as socially triggered cravings, is a critical step in improving treatment for cannabis dependence. In recent years, virtual reality has been studied to determine whether it can be used to induce craving by using life-like cue settings. Researchers are interested in using virtual reality systems to study cannabis cravings in individuals with schizophrenia. Objectives: - To determine if virtual reality cues will elicit cannabis craving in persons with schizophrenia who have a history of cannabis use. Eligibility: - Individuals between 18 and 50 years of age who have been diagnosed with schizophrenia or schizoaffective disorders, are on a stable antipsychotic medication, and who have a lifetime history of at least 50 cannabis uses and average cannabis use of once per month. Design: - This study involves an initial screening visit, a study visit, and a followup visit. - Participants will be screened with a medical history and physical examination, and will complete questionnaires about their history of marijuana and other drug use. Participants will also learn how to use the virtual reality equipment at this visit. - During the study visit, participants will respond to marijuana cues using the virtual reality system while researchers monitor their heart rate, blood pressure, and sweat levels. - At the followup visit, participants will complete questionnaires about their mood and any cravings for marijuana.
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.
