Schizophrenia and bipolar disorder (BD) are complex and multidimensional disorders with high heritability rates. The contribution of genetic factors to the etiology of these disorders is increasingly being recognized as the action of multiple risk variants with small effect sizes, which might explain only a minor part of susceptibility. On the other site, numerous environmental factors have been found to play an important role in their causality. Therefore, in recent years, several studies focused on gene × environment interactions that are believed to bridge the gap between genetic underpinnings and environmental insults...

Cannabidiol (CBD), the main nonpsychotomimetic compound from Cannabis sativa, inhibits experimental seizures in animal models and alleviates certain types of intractable epilepsies in patients. Its pharmacological profile, however, is still uncertain. Here we tested the hypothesis that CBD anticonvulsant mechanisms are prevented by cannabinoid (CB1 and CB2) and vanilloid (TRPV1) receptor blockers. We also investigated its effects on electroencephalographic (EEG) activity and hippocampal cytokines in the pentylenetetrazole (PTZ) model...

BACKGROUND: Little is known about motives for cannabis use among the population of adults using cannabis medically. Therefore, we evaluated the performance of the 12 factor, 36-item Comprehensive Marijuana Motives Questionnaire (CMMQ) among a sample of medical cannabis patients. METHODS: Study participants were adults ages 21years or older with scheduled appointments to obtain new or renewed medical cannabis certification from clinics in one Midwestern state (n=1116)...

PURPOSE: This study sought to undertake an exploratory analysis of the impact of therapeutic alliance and dysfunctional attitudes (perfectionism and need for approval) on outcomes for participants receiving therapist-delivered and eHealth interventions for comorbid depression and alcohol/cannabis use problems. These factors have been shown in previous research to moderate response to psychological treatment for depression and related disorders. METHOD: Participants (N = 274) with concurrent depression and alcohol/cannabis misuse were randomized to 10 sessions of therapist-delivered cognitive behavior therapy/motivational interviewing (CBT/MI), computer-delivered CBT/MI with brief therapist assistance (SHADE CBT/MI), or supportive counseling (PCT)...

BACKGROUND: Healthcare renunciation for economic reasons is a major health concern, but it has been scarcely investigated among drug users, even if drug users constitute a vulnerable population in need of medical care. This study investigated associations of healthcare renunciation for economic reasons and addictive behaviors (alcohol, tobacco, cannabis, illicit drug use, and gambling) in a population-based sample of adults living in France, a country with universal health coverage. METHODS: Data were collected using the 2014 Health Barometer, a French cross-sectional survey conducted among a random representative sample of the general population aged 18-64 (n=12,852)...

Pain associated with integumentary wounds is highly prevalent yet it remains an area of significant unmet need within healthcare. Currently, systemically administered opioids are the mainstay of treatment. However, recent publications are casting opioids in a negative light given their high side effect profile, inhibition of wound healing, and association with accidental overdose, incidents that are frequently fatal. Thus, novel analgesic strategies for wound-related pain need to be investigated. The ideal methods of pain relief for wound patients are modalities that are topical, lack systemic side effects, non-invasive, self-administered, and display rapid onset of analgesia...

BACKGROUND: Since 2005, the Australian Government has subsidized the production and distribution of Low Aromatic Fuel (LAF) as a deterrent against petrol (gasoline) sniffing in remote Indigenous communities. LAF is used in place of unleaded petrol as a fuel for vehicles and other engines. This paper reports findings from an independent evaluation of the LAF rollout. METHODS: Forty one Indigenous communities were surveyed between 2010 and 2014, with each community being visited twice at a two yearly interval...

Cannabis affects cognitive performance through the activation of the endocannabinoid system, and the molecular mechanisms involved in this process are poorly understood. Using the novel object-recognition memory test in mice, we found that the main psychoactive component of cannabis, delta9-tetrahydrocannabinol (THC), alters short-term object-recognition memory specifically involving protein kinase C (PKC)-dependent signaling. Indeed, the systemic or intra-hippocampal pre-treatment with the PKC inhibitors, prevented the short-term, but not the long-term, memory impairment induced by THC...

AIMS: Previous studies indicate that young people who have positive attitudes towards illicit drugs are more inclined to experiment with them. The first aim of our study was to identify the sociodemographic and risk behaviour characteristics of young people (16-24 years) with positive attitudes towards illicit drug use. The second aim was to identify the characteristics of young people with positive attitudes towards illicit drugs among those who had never tried drugs, those who had tried cannabis but no other illicit drugs, and those who regularly used cannabis and/or had tried other illicit drugs...

Prolonged urinary cannabinoid excretion in chronic frequent cannabis users confounds identification of recent cannabis intake that may be important in treatment, workplace, clinical, and forensic testing programs. In addition, differentiation of synthetic Δ9-tetrahydrocannabinol (THC) intake from cannabis plant products might be an important interpretive issue. THC, 11-hydroxy-THC (11-OH-THC) and 11-nor-9-carboxy-THC (THCCOOH) urine concentrations were evaluated during previous controlled cannabis administration studies following tandem alkaline/E...

BACKGROUND: Cannabis is the most commonly and widely used illicit drug in the world and is also the most commonly used drug of abuse in alcohol drinkers. Experimental studies have shown conflicting results of the effects of cannabis on the severity of acute pancreatitis (AP). The purpose of this study is to ascertain the clinical effects of simultaneous alcohol and cannabis use on severity at presentation and outcomes of acute alcoholic pancreatitis (AAP). METHODS: A retrospective review was conducted on the patients discharged with principle or secondary diagnosis of AP using ICD-9 & ICD-10 codes during the time period from January 2006 to December 2015 at a large community-based hospital in Central Georgia...

BACKGROUND: Cannabis is the most commonly used illicit drug in the US, and is associated with a range of psychological, social, and physical health-related problems. Individuals who endorse elevated levels of social anxiety are especially at risk for experiencing cannabis-related problems, including cannabis use disorder, despite not using cannabis more often than those with more normative social anxiety. Identification of mechanisms that underlie the relationship between social anxiety and cannabis-related problems may inform treatment and prevention efforts...

This commentary to the editorial of Hajizadeh argues that the economic, social and health consequences of legalizing cannabis in Canada will depend in large part on the exact stipulations (mainly from the federal government) and on the implementation, regulation and practice of the legalization act (on provincial and municipal levels). A strict regulatory framework is necessary to minimize the health burden attributable to cannabis use. This includes prominently control of production and sale of the legal cannabis including control of price and content with ban of marketing and advertisement...

Recent policy changes have led to significant increases in the use of cannabis for both medical and recreational purposes. Although men are more likely to endorse past month cannabis use and are more frequently diagnosed with Cannabis Use Disorder relative to women, a growing proportion of medical cannabis users are reported to be women. The increased popularity of cannabis for medical purposes and the narrowing gap in prevalence of use between men and women raises questions regarding sex-dependent effects related to therapeutic efficacy and negative health effects of cannabis and cannabinoids...

BACKGROUND: Recent decades have seen substantial changes in the UK cannabis landscape, including increased domestic production, the ascendancy of stronger strains (namely 'skunk') and the drug's reclassification under the 1971 Misuse of Drugs Act. Resultantly, cannabis retains significance in the consciousness, priorities and policy agendas of communities, drug services and criminal justice agencies. METHODS: This paper presents an empirical study, which examined both perceptions and impacts of cannabis cultivation and its control within a North-West English borough...
