NCT ID: NCT05160688 Enrolling by invitation - Cannabis Clinical Trials

Changes in Cognition and Psychiatric Disorder Symptoms During Cannabis Abstinence Using a Novel Discordant Twin Design

Start date: May 5, 2023
Phase: N/A
Study type: Interventional

This study will test whether 42 days of cannabis abstinence, compared to continued cannabis use, is associated with improvements in cognition and psychiatric disorder symptoms. Identical twins, who are concordant on cannabis use, will be experimentally-manipulated to be discordant for 42 days. Each twin, within a twin pair, will be randomly assigned to either the contingency management condition, incentive-based protocol to promote cannabis abstinence, or control condition, no changes in cannabis use requested.

NCT ID: NCT05116527 Recruiting - Cannabis Clinical Trials

THC Memory & Reward Learning Pilot

Start date: July 7, 2022
Phase: Phase 1/Phase 2
Study type: Interventional

Tetrahydrocannabidiol (THC) is the psychoactive chemical in cannabis that makes people high. This study aims to dissect acute impairment of various forms of memory and learning by THC in cannabis compared to placebo. Impairment will be assessed via a short cognitive test battery and then subjects will complete four tasks in the fMRI scanner.

NCT ID: NCT05115318 Completed - Tourette Syndrome Clinical Trials

The Effect of Medical Cannabis on Tics, Premonitory Urge and Psychiatric Comorbidity in Adults With Tourette Syndrome

Start date: July 1, 2020
Phase:
Study type: Observational

Medical cannabis (MC) is a standard treatment in Israel to adults with resistant Gilles de la Tourette syndrome (GTS). While small randomized control trials assessed THC efficacy on tics and premonitory urge, only small retrospective studies assessed MC efficacy and tolerability in GTS. Herein, By using an open-label, prospective design, our aim is to determine the preferred method of use, efficacy and tolerability of 12 weeks of treatment with MC in adult patients with GTS.

NCT ID: NCT05049733 Completed - Cannabis Clinical Trials

The Pharmacokinetics and Pharmacodynamics of a Single Acute Dose of a Hemp-derived Oral Product With a 1:1 Ratio of CBD:CBD-A

Start date: March 7, 2022
Phase: Phase 1
Study type: Interventional

The purpose of this study is to examine the pharmacokinetics and pharmacodynamics of a hemp-derived oral product containing cannabidiol (CBD) and cannabidiolic acid (CBD-A) at a 1:1 ratio.

NCT ID: NCT04997954 Active, not recruiting - Clinical trials for Amyotrophic Lateral Sclerosis

EMERALD TRIAL Open Label Extension Study

EMERALD-OLE
Start date: May 17, 2021
Phase: Phase 4
Study type: Interventional

EMERALD OLE trial is an open-label extension of the EMERALD trial. Long term tolerability and safety of the MediCabilis CBD oil has not been extensively studied. EMERALD OLE aims to establish data on the prolonged used of the study drug product. All participants who completed the EMERALD trial will be offered to enter EMERALD OLE. Participants will be taking the active drug MediCabilis CBD oil for 6 months.

NCT ID: NCT04945031 Completed - Cannabis Clinical Trials

The Study of Pharmacological Treatment Pattern for Cannabis-induced Psychosis

Start date: November 8, 2019
Phase:
Study type: Observational

A cross-sectional and retrospective chart review study was conducted at the Princess Mother National Institute on Drug Abuse Treatment (PMNIDAT), Thailand. All patients who admitted at PMNIDAT from October 2013 to September 2019 were included. Patients aged 18-65 years who met the International Classification of Disease-10 (ICD-10) criteria of CIP and Had a positive urine test of cannabis were included. Cannabis use is a component cause of psychosis.More than half of symptoms of cannabis-induced psychosis (CIP) were hallucination, delusion, irritable and anxiety. Antipsychotic drug was still a key psychotropic drugs for treatment of CIP. However, antidepressants and benzodiazepines were commonly used for treatment of other symptoms beyond psychotics

NCT ID: NCT04911127 Completed - Clinical trials for Rheumatoid Arthritis

Therapeutic Response of Cannabidiol in Rheumatoid Arthritis

Start date: October 5, 2021
Phase: Phase 1
Study type: Interventional

The study will randomly assign Rheumatoid Arthritis (RA) patients on stable RA therapy to either placebo or cannabidiol (CBD). The overall goal of this proposal is to examine the efficacy and safety of CBD treatment as adjunctive to the medical management of RA patients.

NCT ID: NCT04860089 Withdrawn - HIV Infections Clinical Trials

Pain, Inflammation, and Cannabis in HIV

PITCH-E
Start date: August 2022
Phase:
Study type: Observational

This study will examine how medical cannabis use affects neuropathic pain, inflammation and adverse events in people living with HIV (PLWH) with neuropathic pain. We will study how varying ratios of THC and CBD in medical cannabis impact neuropathic pain, inflammation and adverse events.

NCT ID: NCT04851392 Completed - Cannabis Use Clinical Trials

Do Adolescents and Adults Differ in Their Acute Response to Cannabis?

CannTeenA
Start date: March 11, 2019
Phase: N/A
Study type: Interventional

The acute effects of cannabis may differ between adolescents and adults. Furthermore, these effects may be tempered by the presence of cannabidiol. This double-blind, placebo-controlled, crossover experiment investigates the acute effects of cannabis (with and without cannabidiol) on subjective effects, behavioural responses and neural functioning in 16-17 year-olds and 26-29 year-olds who regularly use cannabis (0.5-3 days per week).

NCT ID: NCT04816994 Recruiting - Cannabis Clinical Trials

Effect of Cannabis Extract on Acute Radicular Pain and on Analgesic Requirement

Start date: January 7, 2018
Phase: Phase 3
Study type: Interventional

Clinical evidence about the effects of cannabis in the management of acute pain is rather scarce, mostly consisting of case report-based opinions on adverse events during or after general anesthesia after smoking cannabis, experimental pain trials in healthy volunteers, and a few clinical trials using different drugs, dosages and routes of administration. It is difficult to draw strong conclusions from the available evidence, that may seem sometimes even contradictory, mainly due -the investigators believe- to the many sources of variability in the study designs (e.g.: heterogeneity of the study samples, underpowered, unblinding, lack of randomization, timing of the therapeutic intervention, different experimental pain models, inclusion of different kind of surgical pain, etc.). Nevertheless, expert's opinion after a critical review of the literature is that cannabis and cannabinoids may have a beneficial role in the management of acute pain, at least for a selected group of patients and through an appropriate therapeutic intervention. Cannabis oil seem to be most suitable to our investigation. The co-administration of tetrahydrocannabinol (THC) with cannabidiol (CBD) may translate into additional therapeutic benefits with an attenuation of adverse effects. And will help treat acute radicular back pain
