Active clinical trials for "Marijuana Abuse"

Cannabis use is increasing and will only further escalate with legalization of recreational and medical cannabis use in western countries , with a prevalence greater than 30 % in the US and most European countries for individuals between 16 and 24 years of age. Approximately 9 % of those who use cannabis will become addicted. The number goes up to about 1 in 6 among those who start using cannabis as teenagers and to 25 to 50 % among those who smoke cannabis daily. The consequences of cannabis abuse in the most prone population (14-25 years of age) are extremely serious, and may include addiction, altered brain development, poorer educational outcomes, cognitive impairment, lower income, greater welfare dependence, unemployment and lower relationship and life satisfaction. There are no available pharmacological treatments of cannabis use disorder (CUD). Thus, the development of safe and effective medications for the treatment of CUD is an urgent public health priority. The preclinical efficacy and available ADMET (Administration, Distribution, Metabolism, Elimination and Toxicology) in animal and human data suggest that AEF0117, an investigational new study drug, could constitute a very efficacious and safe treatment for cannabis abuse disorders. The purpose of this research is to study how AEF0117 influences the subjective effects of cannabis in subjects with CUD. AEF0117 acts in the same parts of the brain as THC (tetrahydrocannabinol), the active ingredient of marijuana, and may temporarily alter some of cannabis's effects. This will be a single center study in healthy male and non-pregnant female, non-treatment seeking, cannabis smoking subjects with cannabis use disorder (CUD). The study design will be a randomized, double-blind, placebo-controlled, cross-over design, multiple dose escalation study with AEF0117. This study is designed to test the effects of two to four doses of AEF0117 compared to placebo on primarily peak subjective effects of cannabis as primary objectives. The secondary objectives are to test the effects of AEF0117 compared to placebo on cannabis self-administration, on cannabis-induced analgesia and on cognitive performance in cannabis smoking subjects. The study hypothesis is that AEF0117 will decrease ratings of cannabis' positive subject effects (e.g., 'good drug effect', high) and decrease cannabis self-administration compared to placebo and also decrease the other unconditioned effects of cannabis studied here. Each subject will have a screening visit, then be included for two 6-day inpatient periods separated by a minimum 14-day outpatient washout. Subjects will be advised that they will receive both active and placebo study medication but will remain blinded to whether they will receive AEF0117 or placebo on Period A and Period B. Each period is composed of 5 consecutive days of treatment (active or placebo), one administration per day. Research staff that interacts with study subjects will also remain blinded to whether subjects are receiving AEF0117 or placebo. The study duration for the first 3 doses of AEF0117 is estimated to be approximately up to 10 months from the start of subject recruitment to the last subject last visit.

The purpose of this pilot project is to pilot-test a combined cannabis and smoking cessation treatment. The intervention combines mobile technology with behavioral strategies, counseling, and medications.

The primary objective of this study was to evaluate the pharmacokinetics (PK) of THC, 11-OH-THC and CBD following a single inhaled dose of PPP001 administered by vaporization. The secondary objective of this study was to determine the safety and tolerability of THC and CBD after a single inhaled dose of PPP001 administered by vaporization in healthy volunteers.

The proposed study is a double-blind, placebo-controlled, cross over study on 60 children aged 5 to 25 years with severe spasticity related to cerebral palsy (CP), level IV and V with full-spectrum medical cannabis product of CBD/THC ratio 10:1.

The CanCope Study is a micro-randomized trial conducted to gather evidence about and compare the effectiveness of a momentary intervention to help young adults cope with cannabis cravings as they attempt to reduce their use.

This is an unblinded pilot study of an environmental exposure to secondhand cannabis smoke in one group of healthy nonsmokers.

This study is being completed to pilot prevention methods to promote wellness and reduce risky behaviors, including the use of substances such as cannabis. This study will help researchers learn about ways of delivering this information that is both appealing and helpful to young adults who use mobile apps.

General objective: To assess the effectiveness of a treatment program specific for cannabis abuse (cognitive behavioral treatment + pharmacological treatment) compared to standard treatment (pharmacological treatment + psychoeducation) in patients with first episodes psychosis (FEP) cannabis users. Design A multicenter single-blind randomized study with 1 year of follow-up. The effectiveness of a treatment program specific for cannabis abuse (cognitive behavioral treatment + pharmacological treatment) compared to standard treatment (pharmacological treatment + psychoeducation) in patients with first episodes psychosis (FEP) cannabis users will be assessed. Patients will be randomly assigned to one of two treatments: Experimental group (N=50): Cognitive-behavioral treatment specific for cannabis abuse + pharmacological treatment Control group (N=50): standard treatment: psychoeducation + pharmacological treatment

This pilot study gathered preliminary evidence of the safety and efficacy of four potencies of smoked cannabis to manage chronic, treatment-resistant PTSD among veterans: (1) High THC/ Low CBD (High THC), (2) Low THC/High CBD (High CBD), (3) High THC/ High CBD (THC/CBD) and (4) Low THC/Low CBD (placebo). The study will produce preliminary evidence to help elucidate the potential effects of THC, CBD, or a combination of both constituents to reduce PTSD symptoms. Smoked cannabis will be tested in two stages of three weeks each (Stage 1 and Stage 2), with a two-week cessation period after each stage, verified by blood/urine cannabinoid analysis. The primary objective was to compare three active concentrations of smoked cannabis and placebo on PTSD symptom severity measured by CAPS-5 total severity scores during Stage 1.

This project aims to develop and test an intervention for the simultaneous treatment of cannabis use disorders and tobacco smoking. This is important because over 50% of adults seeking treatment to help stop cannabis use also smoke tobacco regularly, which decreases their chance for a successful treatment outcome and increases adverse acute and long-term psychosocial and health consequences. The proposed treatment will integrate existing computer-based behavioral interventions for cannabis and tobacco and use nicotine replacement medications to improve outcomes in this difficult to treat clinical population.
