Substance-induced psychosis (SIP) is frequent in substance use disorder patients. However, little is known about the presence of SIP in Borderline Personality Disorder (BPD) and what the risk factors for the development of SIP in this population would be. A sample of 91 BPD drug-dependent patients attending an outpatient substance use disorder unit was evaluated. Comorbidity with Axis I and II was assessed using SCID-I and SCID-II. Psychoactive drug related variables were registered as well as the presence of the ninth criterion of DSM-IV-TR as a code of psychotic symptoms...

OBJECTIVE: To examine if a substance use disorder (SUD), especially cannabis use disorder in adolescence, predicts future medical cannabis card status among high-risk youth. METHODS: Data collection occurred in Denver and San Diego. We recruited adolescents, with or at high risk for SUD and conduct problems (hereafter probands) and their siblings (n=654). Baseline (Wave 1) assessments took place between 1999 and 2008, and follow-up (Wave 2) took place between 2010 and 2013...

Hallucinogen-persisting perception disorder (HPPD) is a syndrome characterized by prolonged or reoccurring perceptual symptoms, reminiscent of acute hallucinogen effects. HPPD was associated with a broader range of LSD (lysergic acid diethylamide)-like substances, cannabis, methylenedioxymethamphetamine (MDMA), psilocybin, mescaline, and psychostimulants. The recent emergence of novel psychoactive substances (NPS) posed a critical concern regarding the new onset of psychiatric symptoms/syndromes, including cases of HPPD...

Background: Cannabis use in young people is common and associated with psychiatric disorders. However, the prospective link between cannabis use and bipolar disorder symptoms has rarely been investigated. The study hypothesis was that adolescent cannabis use is associated with hypomania in early adulthood via several potential etiological pathways. Methods: Data were used from the Avon Longitudinal Study of Parents and Children, a UK birth cohort study. The prospective link between cannabis use at age 17 and hypomania at age 22-23 years was tested using regression analysis, adjusted for gender, early environmental risk factors, alcohol and drug use, and depression and psychotic symptoms at age 18 years...

Decisional Balance and Processes of Change are generally addressed in motivational interventions for the treatment of cannabis use disorders. However, specific aspects of these multifaceted constructs, with greater relevance for severe cannabis users, need to be ascertained to enable better interventions. This study aimed to compare the different facets of decisional balance and processes of change between mild and severe cannabis users in a community-based sample of young undergraduates. Thirty-one severe cannabis users and 31 mild cannabis users, indicated with the Severity of Dependence Scale, were assessed using the Decisional Balance Questionnaire (DBQ) and the Processes of Change Questionnaire (PCQ)...

Cannabis-related impairments to cognitive function may represent novel therapeutic targets for cannabis-use disorder, although the nature, persistence, and reversibility of those deficits remain unclear. Adult male rhesus monkeys (N=6) responded in the mornings on tasks designed to assess different cognitive domains using CANTAB touchscreens followed by responding maintained under a fixed-ratio (FR) 10 schedule of food presentation in different operant chambers. First, the acute effects of Δ9-tetrahydrocannabinol (THC; 0...

Purpose of Review: There is not one answer to address whether marijuana use has increased, decreased, or stayed the same given changes in state legalization of medical and non-medical marijuana in the USA. Recent Findings: Evidence suggests some health benefits for medical marijuana; however, initiation of marijuana use is a risk factor for developing problem cannabis use. Though use rates have remained stable over recent years, about one in three 10th graders report marijuana use, most adolescents do not view the drug as harmful, and over 650,000 youth aged 12 to 17 struggle with cannabis use disorder...

Although drug-abusing women try to moderate their drug and alcohol use during pregnancy, they often relapse at a time when childcare needs are high and maternal bonding is critical to an infant's development. In the clinical setting, the search for the neural basis of drug-induced caregiving deficits is complex due to several intervening variables. Rather, the preclinical studies that control for drug dose and regimen, as well as for gestational and postpartum environment, allow a precise determination of the effects of drugs on maternal behaviour...

BACKGROUND: Addiction and related disorders are devastating with their tremendous social, psychological, and physical consequences for which development of optimally effective treatments are long overdue. Repetitive transcranial magnetic stimulation (rTMS) is relatively safe and is becoming an emerging therapeutic tool for these conditions. METHODS: This systematic review was conducted using PubMed, PsycINFO, PsychiatryOnline and Cochrane Library ranging from year 2001 to 2017...

BACKGROUND: Since 2013 Cannabis-based preparations, containing the two main cannabinoids of interest, Δ9-tetrahydrocannabinol (THC), and cannabidiol (CBD), can be used for therapeutic purposes, such as palliative care, neurodegenerative disorder treatment and other therapies. The preparations may consist of a drug partition in sachets, capsules or through the extraction in certified olive oil. OBJECTIVE: the aims of the study were: a) to develop and validate a new liquid chromatographic-tandem mass spectrometric (LC-MS/MS) method for the identification and quantification of THC and CBD in olive oil; b) to evaluate the extraction efficiency and reproducibility of a new commercial extractor on the market...

Parental cannabis use disorder (CUD) and low positive parenting (monitoring, support, and consistency) are risk factors for adolescent cannabis use. However, it is unclear whether parental cannabis use without CUD is sufficient to increase risk for low positive parenting and adolescent cannabis use. Additionally, parents may not treat each of their adolescents the same, and risk for adolescent cannabis use may increase as a result of low levels of positive parenting in families or low positive parenting unique to each adolescent...

During adolescence, problems reflecting cognitive, behavioral and affective dysregulation, such as inattention and emotional dyscontrol, have been observed to be associated with substance use disorder (SUD) risks and outcomes. Prior studies have typically been with small samples, and have typically not included comprehensive measurement of executive dysfunction domains. The relationships of executive dysfunction in daily life with performance based testing of cognitive skills and structural brain characteristics, thought to be the basis for executive functioning, have not been definitively determined...

INTRODUCTION: Over 12% of US adults report past-year cannabis use, and among those who use daily, 25% or more have a cannabis use disorder. Use is increasing as legal access expands. Yet, cannabis use is not routinely assessed in primary care, and little is known about use among primary care patients and relevant demographic and behavioral health subgroups. This study describes the prevalence and frequency of past-year cannabis use among primary care patients assessed for use during a primary care visit...

OBJECTIVE: The authors investigated the rates of conversion to schizophrenia and bipolar disorder after a substance-induced psychosis, as well as risk factors for conversion. METHOD: All patient information was extracted from the Danish Civil Registration System and the Psychiatric Central Research Register. The study population included all persons who received a diagnosis of substance-induced psychosis between 1994 and 2014 (N=6,788); patients were followed until first occurrence of schizophrenia or bipolar disorder or until death, emigration, or August 2014...

The medicinal use of marijuana has been legalized in 28 states, with a wide range of specificity for approved medical conditions. Even with the emergence of non-combustion-based delivery systems, in 2014, 90% of marijuana users used smoked marijuana. The purpose of this review is to summarize the data available on use of smoked marijuana for medical purposes. A literature search was performed to retrieve randomized controlled trials exploring the efficacy of smoked cannabis for treatment of a medical condition...

The aim of this study was to examine whether cannabis use, childhood trauma and urban upbringing are associated with total gray matter volume (GMV) in individuals with (risk for) psychotic disorder and whether this is sex-specific. T1-weighted MRI scans were acquired from 89 patients with a psychotic disorder, 95 healthy siblings of patients with psychotic disorder and 87 controls. Multilevel random regression analyses were used to examine main effects and interactions between group, sex and environmental factors in models of GMV...

BACKGROUND: In the United States, cannabis accessibility has continued to rise as the perception of its harmfulness has decreased. Only about 30% of regular cannabis users develop cannabis use disorder (CUD), but it is unclear if individuals who use cannabis regularly without ever developing CUD experience notable psychosocial impairment across the lifespan. Therefore, psychosocial functioning was compared across regular cannabis users with or without CUD and a non-user control group during adolescence (age 17; early risk) and young adulthood (ages 18-25; peak CUD prevalence)...

Many studies have suggested the co-occurrence of eating disorders and alcohol use disorders but in which extent binge eating (BE) and other disordered eating symptoms (DES) are associated with the severity of binge drinking (BD) remains unknown. We conducted a online cross-sectional study among 1,872 French students. Participants were asked their age, gender, tobacco and cannabis use status. They completed the Alcohol Use Questionnaire (AUQ), Eating Disorder Examination Questionnaire (EDE-Q), and UPPS impulsive behavior questionnaire...

One in five patients with a psychotic disorder has persistent low subjective well-being (SWB), which is associated with a poorer prognosis. In schizophrenia patients, personality traits are associated with SWB. The present study aims to evaluate whether neuroticism and extraversion influence SWB in patients with a psychotic disorder and healthy controls over the course of time. In 186 patients and 126 healthy control subjects, SWB was measured with the Subjective Well-being under Neuroleptics-20 (SWN) scale at baseline, three years and six years...

BACKGROUND: Inclusion health focuses on people in extremely poor health due to poverty, marginalisation, and multimorbidity. We aimed to review morbidity and mortality data on four overlapping populations who experience considerable social exclusion: homeless populations, individuals with substance use disorders, sex workers, and imprisoned individuals. METHODS: For this systematic review and meta-analysis, we searched MEDLINE, Embase, and the Cochrane Library for studies published between Jan 1, 2005, and Oct 1, 2015...
