Filter by:The goal of this interventional study is to learn about the effect of Medicinal Cannabis (Bedrocan®) on Fibromyalgia patients with pain resistant to conventional therapy. The main question the trial aims to answer are: - Is Bedrocan® effective for treating fibromyalgia-related pain in patients resistant to conventional therapy? - Can a low dosage of medical cannabis taken as a decoction reduce fibromyalgic pain? All patients were trained on how to make the decoction: therapy was started with 100 mg/day (1 folder) and increased to 200 mg/day (2 folders) in non-responders.
The number of youngsters abusing cannabis is surging, the public health consequences caused by cannabis can be unpredictable. Educating the public especially the young population about cannabis need to be highlighted. To successfully promote anti-cannabis messages to youngsters and prevent them from taking cannabis, the involvement of their parents and modern technology such as robots can be helpful. This project aims to educate the young population and their parents about cannabis, particularly its legal consequences and clarifying their misconceptions.
The interface between cannabis use and stress is a particularly important focus for sex differences research in emerging adults. Given the dynamics at play in this critical stage when cannabis use is most prevalent, developmentally informed research is needed to guide tailored clinical interventions. This study will apply rigorous and innovative methods to elucidate sex differences in the nexus of cannabis use and stress among emerging adults with cannabis use disorder to guide the development of tailored treatments.
The use of Cannabis is increasing in the population, and the effects that this might have on different medical procedures are poorly understood. Particularly when submitted to deep sedation or general anesthesia, there is no consensus on best drugs or doses to deliver. The purpose of this clinical trial is to clarify the influence of chronic cannabis use during office based general anesthesia for extraction of teeth. The procedures will be performed in the Oral and Maxillofacial Surgery Clinic at the College of Dentistry.
This study investigates the impact of ∆9-tetrahydrocannabinol (THC) and cannabidiol (CBD) on recognition memory in healthy, regular cannabis users. Participants complete the same recognition memory task after self-administering one of three different strains of cannabis flower one day and while not intoxicated another day. Event-related potentials (ERPs) are measured via electroencephalogram (EEG) during the recognition memory task. Blood is collected to quantify THC and CBD exposure. Participants also complete self-report measures of medical history, sleep quality, subjective cognitive function, physical activity, psychological functioning, substance use, and acute drug effects.
There has been a considerable rise in cannabis consumption in recent years, with estimates of 200 million individual users globally. Importantly, 3% of these individuals have cannabis use disorder (CUD), with this prevalence increasing to 33% amongst regular users, making it one of the most common substances use disorders (SUDs) worldwide. CUD is associated with substantial health, societal, and economic costs, and worsening of other psychiatric disorders. Despite this clinical burden, effective treatment options are limited. No pharmacological treatments have emerged as clearly efficacious, and psychotherapeutic interventions have shown tempered results. Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive brain-based approach in which alternating magnetic fields are applied to the scalp to induce electrical currents in cortical tissue. As it can modulate neural circuits implicated in neuropsychiatric disorders, it is a promising brain-based approach in the treatment of addictions. Evidence has indicated its efficacy in reducing drug craving and consumption across numerous SUDs, although research into cannabis has been largely unexplored. Recently, a novel circular rTMS coil, the MagVenture MMC-140, has been developed with the capacity to modulate both the bilateral prefrontal cortex (PFC) and insula, both of which are implicated in the neurocircuitry of craving and executive function. As such, it shows potential for CUD treatment. This proof-of-concept clinical trial will evaluate the feasibility and tolerability of a 4-week course of rTMS to the PFC/insula using MMC-140 as a treatment for CUD. Feasibility of both high frequency (HF; excitatory) and low frequency (LF; inhibitory) stimulation parameters will be evaluated. In addition, pre/post rTMS changes in cannabis use outcomes (e.g., consumption, craving, and withdrawal), executive function, and PFC/insula functional connectivity will be explored. By comprehensively investigating clinical, cognitive, and neuroimaging effects of rTMS, this study could pave the way for the first brain-based intervention in CUD that could be widely adopted into clinical settings using a novel, cost-effective and accessible rTMS device.
This 2-arm study will recruit participants with 1) alcohol use disorder and 2) cannabis use disorder for a 12-week cognitive behavioral therapy, following a thorough baseline assessments on executive function, incentive salience, and negative emotionality.
This study consists in the the design, implementation, and evaluation of the first web-based computer tailored intervention program aimed at the prevention of cannabis use in Spanish adolescents (ALERTA CANNABIS). A Cluster Randomized Controlled Trial is conducted to test the effectiveness of ALERTA CANNABIS in students aged 14 to 18 years across 34 high schools from Andalusia (southern Spain), which are randomized either to the experimental or the control condition (EC and CC).
To collect information about how patients in the pain management clinic use cannabis/CBD, including how often it is used, why it is used (for example, to manage pain or other symptoms), and where patients get their information on cannabis/CBD for pain management
The goal of this clinical trial is to investigate the (cost-)effectiveness of contingency management (CM) compared with Cognitive Behavioural Therapy (CBT) for the treatment of cannabis use disorder (CUD) in youth (16-22 years). The main questions it aims to answer are: - What is the efficacy of 12 weeks outpatient CM versus CBT in youths with a CUD, in terms of cannabis abstinence during the intervention period? - What is the long-term efficacy of CM versus CBT at 6- and 12-months follow-up (FU)? - What is the cost-effectiveness of CM versus CBT at 12-months FU from a societal perspective? Study hypotheses are: 1. CM will result in more cannabis-abstinent days than CBT during the intervention; 2. CM is more effective and cost-effective than CBT at 12 months follow-up. Eligible patients (n=154) will be randomly assigned to either 12 weeks of outpatient CM or CBT. Assessments are conducted by trained research-assistants at baseline, after 6, 12, 26 and 52 weeks, and twice-weekly during treatment and consist of questionnaires, a computer task and collection of urine samples. Primary endpoint is the number of biochemically verified cannabis abstinent days in the 12-week treatment period. Key secondary endpoint: Treatment response: 50% or more reduction in cannabis use days in the past 4 weeks, compared with baseline. The primary outcome will be modelled in the intention-to-treat population in a (negative binomial) regression analysis with treatment group as independent variable and stratification variables as covariates. Cost-effectiveness and cost-utility analysis (CEA; CUA) will be performed from a societal perspective. CEA: Treatment response is the central clinical endpoint for calculations of incremental costs per responder. CUA: Incremental costs per QALY (based on EuroQoL).
