AIM: The Cannabis Experiences Questionnaire (CEQ) was developed to measure the subjective experiences of cannabis use both during and after intoxication. Despite the need to better understand the nature of the complex and significant relationship between cannabis use and early psychosis, this questionnaire has rarely been used in individuals with first-episode psychosis. METHODS: We conducted a set of factor analyses using CEQ data from 194 first-episode psychosis patients who used cannabis in order to uncover the underlying factor structure of the questionnaire and thus the overarching types of psychological experiences during/after using cannabis in young people with psychotic disorders...

PURPOSE/BACKGROUND: In animal models, levels of the neurosteroid pregnenolone increase after tetrahydrocannabinol (THC) administration and pregnenolone appears to attenuate the brain effects of THC. Given these interactions between pregnenolone and THC, we evaluated baseline neurosteroid levels in participants with a history of a cannabis use disorders (CUDs). METHODS/PROCEDURES: Bipolar depressed participants were enrolled in a randomized placebo-controlled clinical trial to evaluate the efficacy of add-on pregnenolone for depression and before receiving pregnenolone or placebo...

OBJECTIVES: Episodes of agitation are frequent in intoxicated patients who have a substance use disorder, a psychiatric disorder or both (dual diagnosis). For managing the agitation, it is necessary to act promptly in a safe environment and addressing any underlying etiology. Inhaled loxapine improves symptoms of agitation in adults with psychiatric disorders (eg, schizophrenia) within 10 minutes of administration. Recently, some reports have documented the usefulness of loxapine in dual diagnoses patients with agitation...

Cannabis use disorders are frequently comorbid in patients with a psychotic disorder and are associated with worse outcomes. To date there are no proven effective strategies to achieve cannabis abstinence in this population. An alternative for abstinence might be harm reduction, i.e. replacing the use of street cannabis with high tetrahydrocannabinol and low cannabidiol levels by medicinal cannabis variants with relatively low tetrahydrocannabinol and relatively high cannabidiol levels, thereby reducing the psychosis inducing effects of cannabis and enhancing the antipsychotic effects of cannabis...

BACKGROUND: The current prevalence rate of substance abuse and dependence, represents an increasing trend of substance abuse and dependence among women, and the results of epidemiology studies indicate that substance use patterns are different between men and women. This study aimed to determine gender differences in substance use patterns and disorders among the patients undergoing methadone maintenance treatment. METHODS: This cross-sectional study was conducted throughout a specified time bracket ranging from September 2012 through March 2013 in Methadone Maintenance Treatment (MMT) clinics of Mashhad, Iran...

The regular use of cannabis generates pronounced cognitive disorders, especially in users who begin before the age of 15-16. However, less is known about the impact of regular cannabis on visual function, especially in the case of early onset. Cannabinoid receptors (CB1) are expressed in areas of the visual system, like the thalamus and primary cortex, which might originate sensory disorders. Hence, we measured contrast sensitivity (CS) in three groups, i.e. cannabis users with late onset of cannabis use (after 16 years old), cannabis users with early onset"...

BACKGROUND: The human intestinal microbiota exerts beneficial or harmful effects in several disorders. Many factors, including alcohol consumption, may influence its composition and trigger bacterial translocation. Excessive alcohol consumption increases gut permeability and translocation of endotoxin into peripheral circulation. Although plasma endotoxin concentrations have been measured often, quantitative changes following alcohol withdrawal have never been described in subjects with alcohol use disorder (AUD)...

Previous research has examined clinicians' acceptance of non-abstinence for clients who have a substance use disorder (SUD), but many SUD clients also present with a psychiatric disorder. To evaluate the acceptability of non-abstinence as a final outcome goal for clients with co-occurring diagnoses, we recruited a nationwide sample of 751 American substance abuse counselors to complete a web-based questionnaire. Respondents rated the acceptability of limited/moderate consumption by clients diagnosed with each of 18 co-occurring disorders: three psychiatric disorders (Major Depressive Disorder, Post-Traumatic Stress Disorder, Social Phobia) x three substances (alcohol, cannabis, opioids) x two levels of severity (DSM-5 Moderate SUD, DSM-5 Severe SUD)...

BACKGROUND: A staggering number of Americans are dying from overdoses attributed to prescription opioid medications (POMs). In response, states are creating policies related to POM harm reduction strategies, overdose prevention, and alternative therapies for pain management, such as cannabis (medical marijuana). However, little is known about how the use of cannabis for pain management may be associated with POM use. PURPOSE: The purpose of this article is to examine state medical cannabis (MC) use laws and policies and their potential association with POM use and related harms...

BACKGROUND: People who inject drugs (PWID) have an elevated risk of suicide attempt. While different substances are associated with suicide attempt, the overall risk posed by binge behavior, a high risk pattern of drug use, remains unclear. Our objective is to assess the association between binge drug use and suicide attempt in a prospective cohort of PWID in Montreal, Canada. METHODS: Participants answered a biannual interviewer-administered questionnaire compiling information on sociodemographics, pattern of substance use (cocaine, amphetamine, opioids, sedative-hypnotics, alcohol and cannabis), psychosocial stressors and related markers...

Cocaine is the third most common substance of abuse after cannabis and alcohol. The use of cocaine as an illicit substance is implicated as a causative factor for multisystem derangements ranging from an acute crisis to chronic complications. Vasospasm is the proposed mechanism behind adverse events resulting from cocaine abuse, acute ischemic strokes (AIS) being one of the few. Our study looked into in-hospital outcomes owing to cocaine use in the large population based study of AIS patients. Using the national inpatient sample (NIS) database from 2014 of United States of America, we identified AIS patients with cocaine use using International Classification of Disease, Ninth Revision (ICD-9) codes...

BACKGROUND: Violence is a major concern and is prevalent across several mental disorders. The use of substances has been associated with an exacerbation of psychiatric symptoms as well as with violence. Compared to other substances such as alcohol and cocaine, existing literature on the cannabis-violence relationship has been more limited, with most studies being conducted in the general population, and has shown controversial results. Evidence has suggested a stronger relationship when examining the effects of the persistency of cannabis use on future violent behaviors...

Worldwide medicinal use of cannabis is rapidly escalating, despite limited evidence of its efficacy from preclinical and clinical studies. Here we show that cannabidiol (CBD) effectively reduced seizures and autistic-like social deficits in a well-validated mouse genetic model of Dravet syndrome (DS), a severe childhood epilepsy disorder caused by loss-of-function mutations in the brain voltage-gated sodium channel NaV1.1. The duration and severity of thermally induced seizures and the frequency of spontaneous seizures were substantially decreased...

The last decade has witnessed a burgeoning interest in studies exploring the link between psychosis spectrum disorders (PSD) and altered immune function. While epidemiological and clinical studies point to evidence for increased peripheral inflammatory markers in PSD, it is not clear whether peripheral inflammation correlates with central inflammation in the brain. Furthermore, these studies are confounded by multiple methodological and disorder-related factors such as antipsychotic medications, smoking, obesity, and metabolic syndrome, all of which independently contribute to altered inflammation...

BACKGROUND: Schizophrenia (SZ) and bipolar disorder (BD) are heritable, polygenic disorders with shared clinical and genetic components, suggesting a psychosis continuum. Cannabis use is a well-documented environmental risk factor in psychotic disorders. In the current study, we investigated the relationship between SZ genetic load and cannabis use before illness onset in SZ and BD spectrums. Since frequent early cannabis use (age <18 years) is believed to increase the risk of developing psychosis more than later use, follow-up analyses were conducted comparing early use to later use and no use...

BACKGROUND: Patients with schizophrenia and comorbid drug use disorders (DUD) have a severe course of illness. Despite strong evidence that drug use can exacerbate psychotic symptoms, we have limited knowledge of how specific drugs may increase risk of schizophrenia readmission in this group. This study aimed to assess drug-related predictors of readmission for schizophrenia among a national cohort of patients with a history of schizophrenia admitted to DUD treatment. METHODS: A record-linkage study was used to assess drug-related factors associated with readmission to mental health treatment for schizophrenia, using a consecutive cohort of 634 patients admitted to DUD treatment between 2000 and 2006 in Danish treatment services and tracked until February 2013 or death, controlling for baseline psychiatric treatment variables...

Both prospective informant-reports and retrospective self-reports may be used to measure childhood maltreatment, though both methods entail potential limitations such as underestimation and memory biases. The validity and utility of standard measures of childhood maltreatment requires clarification in order to inform the design of future studies investigating the mental health consequences of maltreatment. The present study assessed agreement between prospective informant-reports and retrospective self-reports of childhood maltreatment, as well as the comparative utility of both reports for predicting a range of psychiatric problems at age 18...

BACKGROUND: Recent epidemiological data suggest a resurgence in cocaine use (CU) and cocaine-related problems in the United States. Demographic trends and correlates of problem CU are needed to determine potential factors that may be influencing the increased trend and to inform targeted prevention and intervention strategies. METHODS: Trends in any past-year CU, weekly CU, and cocaine use disorder (CUD) were examined among persons aged ≥12 years using the National Survey on Drug Use and Health from 2011 to 2015...
