Mazzoncini R, Donoghue K, Hart J, Morgan C, Doody GA, Dazzan P, Jones PB, Morgan K, Murray RM, Fearon P. Illicit substance use and its correlates in first episode psychosis. Objective:, To determine if substance use (particularly cannabis) is more frequent among first episode psychosis patients and associated with a more problematic clinical presentation. Method:, All first episode psychosis (FEP) patients presenting to secondary services were recruited from London and Nottingham, over 2 years, in the Aetiology and Ethnicity of Schizophrenia and Other Psychoses study broad framework. Clinical and sociodemographic variables were assessed using a set of standardized instruments. A schedule was created to retrospectively collate substance use data from patients, relatives and clinicians. Results:, Five hundred and eleven FEP were identified. They used three to five times more substances than general population. Substance use was associated with poorer social adjustment and a more acute mode of onset. Cannabis use did not affect social adjustment, but was associated with a more acute mode of onset. Conclusion:, Cannabis has a different impact on FEP than other substances. Large epidemiological studies are needed to disentangle cannabis effect. [source]


Outcome of long-term heroin-assisted treatment offered to chronic, treatment-resistant heroin addicts in the Netherlands

ADDICTION, Issue 2 2010
Peter Blanken
ABSTRACT Aims To describe 4-year treatment retention and treatment response among chronic, treatment-resistant heroin-dependent patients offered long-term heroin-assisted treatment (HAT) in the Netherlands. Design Observational cohort study. Setting and intervention Out-patient treatment in specialized heroin treatment centres in six cities in the Netherlands, with methadone plus injectable or inhalable heroin offered 7 days per week, three times per day. Prescription of methadone plus heroin was supplemented with individually tailored psychosocial and medical support. Participants Heroin-dependent patients who had responded positively to HAT in two randomized controlled trials and were eligible for long-term heroin-assisted treatment (n = 149). Measurements Primary outcome measures were treatment retention after 4 years and treatment response on a dichotomous, multi-domain response index, comprising physical, mental and social health and illicit substance use. Findings Four-year retention was 55.7% [95% confidence interval (CI): 47.6,63.8%]. Treatment Response was significantly better for patients continuing 4 years of HAT compared to patients who discontinued treatment: 90.4% versus 21.2% [difference 69.2%; odds ratio (OR) = 48.4, 95% CI: 17.6,159.1]. Continued HAT treatment was also associated with an increasing proportion of patients without health problems and who had stopped illicit drug and excessive alcohol use: from 12% after the first year to 25% after 4 years of HAT. Conclusions Long-term HAT is an effective treatment for chronic heroin addicts who have failed to benefit from methadone maintenance treatment. Four years of HAT is associated with stable physical, mental and social health and with absence of illicit heroin use and substantial reductions in cocaine use. HAT should be continued as long as there is no compelling reason to stop treatment. [source]


Neuropsychological functioning in buprenorphine maintained patients versus abstinent heroin abusers on naltrexone hydrochloride therapy

HUMAN PSYCHOPHARMACOLOGY: CLINICAL AND EXPERIMENTAL, Issue 7 2009

Abstract Rationale Methadone and buprenorphine are among the most widely employed pharmacological treatments currently available for opioid addiction. Cognitive effects of buprenorphine in abstinent heroin abusers are nevertheless far from being understood. Methods Neuropsychological performance of 18 buprenorphine-maintained patients (BMP) was evaluated relative to that of 32 currently abstinent heroin abusers on naltrexone hydrochloride therapy (FHAN), and 34 non-drug dependent controls. The three groups were demographically balanced. Clinical groups reported histories of similar patterns of drug use and had increased periods of abstinence from any illicit substance use including heroin. Results The BMP group performed poorer than controls on the RAVLT (encoding and delayed recall of verbal information), CTT (conceptual flexibility, executive functions) and the RBANS figure copy (visual perception) and delayed recall of visual information. There were no significant differences in any of the cognitive measures between the BMP and FHAN groups or between the FHAN group and controls. Furthermore, the non-differing percentage of abnormal cases between the two patient groups led us to infer that treatment with either BPM or FHAN is not accompanied by qualitative differences in the cognitive profiles of these patients. Conclusion Overall, results suggest that treatment with naltrexone in abstinent heroin abusers may result in less impairment of cognitive functions compared to treatment with buprenorphine. These findings are relevant for improved prognosis and treatment strategies in opioid dependence. Copyright © 2009 John Wiley & Sons, Ltd. [source]


Prevalence and Patterns of Alcohol Consumption and Health-Risk Behaviors Among High School Students in Thailand

ALCOHOLISM, Issue 12 2009
Sawitri Assanangkornchai
Background:, Underage drinking is a significant social and public health problem in Thailand. We report the prevalence and patterns of alcohol consumption and associated health-risk behaviors using data from a 2007,2008 national school survey. Method: A cross-sectional survey using a self-administered questionnaire was conducted among 50,033 high school and vocational college students from 201 schools in 40 provinces between December 2007 and February 2008. Results: The prevalence rates of past-year drinking, past-30-day binge drinking, and drinking until intoxication were 25.5, 9.5, and 17.3% in boys and 14.5, 3.7, and 7.2% in girls, respectively. Higher school levels, lower grades, living with someone other than their own parents, and having family members with substance or alcohol problems were significantly associated with all kinds of drinking. Binge drinkers were significantly more likely to have drinking consequences, e.g., driving after drinking, nausea and vomiting, and having a hangover than were nonbinge drinkers. The rates of other behavior and emotional problems were 2.5 to 6.7 times as likely in drinkers as nondrinkers, including smoking (35.1% vs. 4.9%), prescription drug misuse (17.7% vs. 6.7%), illicit substance use (17.8% vs. 2.4%), carrying a weapon (6.5% vs. 1.8%), feeling depressed (23.2% vs. 10.9%), suicidal attempt (10.5% vs. 3.8%), and sexual intercourse (30.5% vs. 5.7%). Conclusion: Alcohol consumption is a serious problem among adolescents in Thailand and is strongly associated with various health-risk behaviors. Effective age- and gender-specific interventions should be implemented to discourage underage drinking and associated adverse health and social consequences. [source]


School Disrepair and Substance Use Among Regular and Alternative High School Students

JOURNAL OF SCHOOL HEALTH, Issue 8 2010
Rachel A. Grana MPH
BACKGROUND: The physical environment influences adolescent health behavior and personal development. This article examines the relationship between level of school disrepair and substance use among students attending regular high school (RHS) and alternative high school (AHS). METHODS: Data were collected from students (N = 7058) participating in 2 randomized controlled trials of a school-based substance abuse prevention program implemented across the United States. Students provided substance use and demographic information on a self-reported survey. Data for the physical disrepair of schools were collected from individual rater observations of each school environment. We hypothesized that school disrepair would be positively associated with substance use controlling for individual characteristics and a socioeconomic status proxy. Multilevel mixed modeling was used to test the hypothesized association and accounted for students nested within schools. RESULTS: Findings indicated that students attending AHS with greater school disrepair were more likely to report the use of marijuana and other illicit drugs (ie, cocaine, heroin). Students attending RHS with greater school disrepair were less likely to report smoking cigarettes. CONCLUSIONS: Differences in findings between RHS and AHS students are discussed, and implications for substance use prevention programming are offered. Students attending AHS with greater school disrepair may require more substance abuse prevention programming, particularly to prevent illicit substance use. [source]
