The endocannabinoid (eCB) system is involved in the modulation of the reward system and participates in the reinforcing effects of different drugs of abuse, including alcohol. The most abundant receptor of the eCB system in the central nervous system is the CB1 receptor (CB1R), which is predominantly expressed in areas involved in drug addiction, such as the nucleus accumbens, the ventral tegmental area, the substantia nigra and the raphe nucleus. CB1R is expressed in early stages during development, and reaches maximum levels during early adolescence...

BACKGROUND: The cannabis extract nabiximols (Sativex®) effectively supresses withdrawal symptoms and cravings in treatment resistant cannabis dependent individuals, who have high relapse rates following conventional withdrawal treatments. This study examines the efficacy, safety and cost-effectiveness of longer-term nabiximols treatment for outpatient cannabis dependent patients who have not responded to previous conventional treatment approaches. METHODS/DESIGN: A phase III multi-site outpatient, randomised, double-blinded, placebo controlled parallel design, comparing a 12-week course of nabiximols to placebo, with follow up at 24 weeks after enrolment...

AIM: The aim of this study was to examine the typology of Australian illicit drug consumers to determine whether those who use new psychoactive substances (NPS) differ from those using other illicit substances. METHODS: Data were from the 2013 National Drug Strategy Household Survey, a representative population study; analyses were limited to participants reporting past year illicit drug use (including NPS; n = 3309). Latent class analysis identified groups based on past year substance use, and a weighted multivariable, multinomial regression model was used to examine characteristics associated with group membership...

In the United States, Black men who have sex with men (MSM), between the ages of 18 and 34 years, have the highest rates of new HIV infections. The prevalence of HIV in this population is three to four times higher than their White MSM counterparts. Twelve Black MSM from the Bay Area, nine with HIV and three without HIV, were interviewed regarding their experiences and perceived risks of acquiring HIV. Narrative analysis revealed these themes: (a) tested regularly for HIV, (b) HIV knowledge varied before arriving in San Francisco, (c) condom use typically nonexistent when under the influence of alcohol and other drugs, (d) inability to negotiate sex and condom usage, and (e) sense of anticipation, resignation, and acceptance about acquiring HIV...

We examined who, when, and where people non-fatally drowned of drowned in Amsterdam between January 2011 and December 2015 so that in the future more targeted and effective measures can be taken to prevent drowning. Data on non fatal drownings (N = 515, fire department database) were combined with the forensic medicine data on drowning fatalities (N=88). Who drowns in Amsterdam? The majority of those who drowned were men (82%). A high percentage of the people who drowned were under the influence of alcohol or drugs (up to 55%)...

Recent loosening of state and federal policy restrictions on marijuana, along with changes in social norms regarding marijuana use and decreases in prevalence of other types of substance use, may lead to increases in youth initiating marijuana before other types of substances such as alcohol and tobacco. We investigated predictors and potential consequences of initiating marijuana before other drugs for youth aged 12-21-years in the USA. Nationally representative, cross-sectional survey data from the US National Survey on Drug Use and Health supplied self-reported age of first marijuana, cigarettes, alcohol, other tobacco, and other illegal drug use among 12-21-year-old samples from 2004 to 2014 (n = 275,559)...

Understanding of the temporal changes of hepatic lesions in the progression and regression of non-alcoholic steatohepatitis (NASH) is vital to elucidation of the pathogenesis of NASH, and critical to the development of a strategy for NASH pharmacotherapy. There are challenges in studying hepatic lesion progression and regression in NASH patients due to the slow development of NASH in humans, one being the requirement for multiple biopsies during the longitudinal follow-up. Here we studied lesion progression and regression in the diet-induced animal model of NASH by application or removal of the pathogenic diet for multiple time periods...

Colorectal cancer is a common cause of morbidity and mortality in the United States. Most colorectal cancers arise from preexisting adenomatous or serrated polyps. The incidence and mortality of colorectal cancer can be reduced with screening of average-risk adults 50 to 75 years of age. Randomized controlled trials show evidence of reduced colorectal cancer-specific mortality with guaiac-based fecal occult blood tests and flexible sigmoidoscopy. There are no randomized controlled trials on the effectiveness of colonoscopy to reduce colorectal cancer-specific mortality; however, several randomized controlled trials comparing colonoscopy with other strategies are in progress...

Background: The safety and efficacy of long-term opioid treatment for chronic noncancer pain (CNCP) remains controversial. This study examined whether patients who report problematic opioid use sought help and/or perceived barriers to help-seeking. Methods: Data were collected from 1,086 people prescribed opioids for CNCP via a large prospective cohort called the Pain and Opioids IN Treatment (POINT) study. Patients' characteristics and help-seeking were examined according to scores on the Prescribed Opioids Difficulties Scale (PODS)...

BACKGROUND: Neurocognitive impairment is a frequent and often disabling comorbidity of HIV infection. In addition to antiretroviral therapies, individuals with HIV infection may commonly use nonantiretroviral medications that are known to cause neurocognitive adverse effects (NC-AE). The contribution of NC-AE to neurocognitive impairment is rarely considered in the context of HIV and could explain part of the variability in neurocognitive performance among individuals with HIV. SETTING: Women's Interagency HIV Study, a prospective, multisite, observational study of US women with and without HIV...

BACKGROUND: Insomnia disorder is a subjective condition of unsatisfactory sleep (e.g. sleep onset, maintenance, early waking, impairment of daytime functioning). Insomnia disorder impairs quality of life and is associated with an increased risk of physical and mental health problems including anxiety, depression, drug and alcohol abuse, and increased health service use. hypnotic medications (e.g. benzodiazepines and 'Z' drugs) are licensed for sleep promotion, but can induce tolerance and dependence, although many people remain on long-term treatment...

Mobile phone addiction has attracted much attention recently and is showing similarity to other substance use disorders. Because no studies on mobile phone addiction had yet been conducted in Spain, we developed and validated a questionnaire (Cuestionario de Abuso del Teléfono Móvil, ATeMo) to measure mobile phone abuse among young adults in Spanish. The ATeMo questionnaire was designed based on relevant DSM-5 diagnostic criteria and included craving as a diagnostic symptom. Using stratified sampling, the ATeMo questionnaire was administered to 856 students (mean age 21, 62% women)...

The prevalence of substance use disorders in adults is higher if substance use is initiated during adolescence, underscoring the importance of youth substance use prevention. We examined whether the use of one substance by adolescents is associated with increased risk for using any other substance, regardless of use sequences. In 2017 we examined data from 17,000 youth aged 12-17 who participated in the 2014 National Survey on Drug Use and Health, a sample of nationally representative data on substance use among the U...

In 2015, more than 27 million people in the United States reported that they currently used illicit drugs or misused prescription drugs, and more than 66 million reported binge drinking during the previous month. Data from public health surveillance systems on drug and alcohol abuse are crucial for developing and evaluating interventions to prevent and control such behavior. However, public health surveillance for behavioral health in the United States has been hindered by organizational issues and other factors...
