Filter by:This laboratory study will employ a multi-session experimental design to examine the behavioral economic demand for marijuana, by studying effect of marijuana administration (High THC) on demand for marijuana, and marijuana smoking topography. The study will recruit 100 non-treatment seeking marijuana users who smoke marijuana at least twice weekly.
With the recent availability of vortioxetine, and the surging phenomenon of cannabis misuses amongst young abusers, it is a timely opportunity to conduct an early pharmacotherapy intervention study to offer an evidence-based strategy aiming to stop individuals with cannabis use disorders with depressive or anxiety symptoms, to develop into a more chronic disabling dependence or co-morbid state.
Emerging evidence suggests that it is not the negative affect per se but underlying maladaptive cognitive, behavioral, and emotional responses to it that put an individual at risk of pathological substance use. Maladaptive reactivity to negative affect may account for the association between substance-use and emotional disorders and may contribute to poor treatment outcomes for Substance Use Disorder. Thus, teaching adolescents and young adults (herein referred to as "adolescents") skills to manage negative affect may improve therapeutic outcomes of treatment for substance use disorder. Cannabis-use disorder (CUD) among adolescents is a prevalent and growing public health concern. Maladaptive reactivity to negative affect contributes to the maintenance of CUD and accounts for the associations between symptoms of emotional disorders and cannabis use. Still, maladaptive reactivity to negative affect has not yet been targeted in an intervention for CUD. Thus, the overarching aim of this proposal is to develop and pilot test a treatment for CUD that emphasizes the reduction of maladaptive responding to negative affect in adolescents. Participants will be placed in either a standard cognitive behavioral therapy for CUD, or the proposed affective management therapy. The investigators hypothesize that affective management training will yield greater reductions in the participants' use of cannabis, as well as greater improvements to the participants' negative thoughts and emotions, compared to the standard cognitive behavioral therapy.
Sex and gender differences in behavioral, biological, and clinical correlates of substance use disorders are myriad, yet there exists a dearth of gender-informed treatment options. Ovarian hormones have been identified as potential mechanisms of these disparities , and recent clinical trials have begun to examine their utility as possible pharmacotherapeutic agents. The ovarian hormone progesterone has shown promise as a treatment for female cocaine and nicotine users, but has not yet been tested for cannabis. Gender differences in cannabis withdrawal, which is associated with relapse, are pronounced and several studies report more severe and impairing withdrawal symptoms in women compared to men. Developing pharmacological interventions for cannabis withdrawal remains an important priority given the significant cognitive, psychiatric, and physical consequences of heavy cannabis use.
This study tests the feasibility of an intervention to prevent risky alcohol or marijuana use that adds a 4-week course of tailored text messaging to a brief motivational intervention for 13-18-year-old adolescents.
A Phase 2B, 8-Week, Randomized, Double-Blind, Placebo-Controlled, Parallel Group Study to Evaluate the Efficacy, Safety and Tolerability of the Fatty Acid Amide Hydrolase (FAAH) Inhibitor PF-04457845 in Adults with DSM-5 Current Cannabis Use Disorder (CUD)
The proposed 2-week, double-blind, crossover, proof of concept study aims to measure and manipulate core neurochemical (i.e., dysregulated brain GABA/glutamate homeostasis) and neurobehavioral (i.e., elevated impulsivity) dysfunctions characteristic of individuals with cannabis use disorder (CUD) and Bipolar Disorder (BD), using a medication that has been shown to increase cortical GABA (i.e., gabapentin) levels in past research, and to evaluate medication-related changes in response inhibition (go no-go) and cannabis cue reactivity functional Magnetic Resonance Imaging tasks, as well as cannabis use, mood symptoms (including anxiety and sleep), and impulsivity in individuals with CUD+BD.
This study will use a randomized controlled design to test whether 30 days of cannabis abstinence, compared to 30 days of monitoring, is associated with improvements in cognitive functioning. Non-using controls will also be enrolled to determine the clinical significance of any cognitive improvements with abstinence.
The purpose of this pilot research study is to test whether certain components of the marijuana plant, known as "cannabinoids", may help to reduce symptoms in patients with OCD. Specifically, patients enrolled in the study will smoke marijuana containing different concentrations of 2 different cannabinoids, THC and CBD. Both of these agents act on the brain's "endocannabinoid system," which has been hypothesized to play a role in OCD. Neither compound is currently FDA-approved for treating OCD.
The study will examine how medical cannabis use affects opioid analgesic use over time, with particular attention to THC/CBD content, HIV outcomes, and severe adverse events.
