Drug use in Ireland and Northern Ireland 2010/11 Drug Prevalence Survey: Polydrug Use Results: Bulletin 5

This bulletin presents key findings regarding polydrug use (the use of more than one substance within a specific time period) in Ireland. These are based on the drug prevalence survey of households in Ireland and Northern Ireland. A representative sample of adults aged between 15 and 64 years was sampled during late 2010 and early 2011. The bulletin presents prevalence rates for combinations of both legal and illegal drug use for the Republic of Ireland and also examines gender and age differences and the relationship between the use of a particular substance and the use of another substance. The survey was carried out according to standards set by the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA). View the report here.

Routes of administration of cannabis used for nonmedical purposes and associations with patterns of drug use.

PURPOSE: Little is known regarding cannabis administration routes for nonmedical use-that is, its delivery methods (e.g., joints, water pipe, food). Therefore, we examined the prevalence rates of different cannabis delivery methods and assessed the relationship of the distinct administration routes with problematic drug use. Subgroups of cannabis users were also investigated (i.e., "pure" cannabis users, previously described as employing a harmless route of administration, and water pipe users, previously described as using a harmful route of administration). METHODS: As part of the Cohort Study on Substance Use Risk Factors, 1,763 cannabis users answered questions concerning their drug use (i.e., routes of administration, problematic cannabis use, other illicit drug use). Descriptive statistics, latent class analysis, correlations and t-tests were assessed. RESULTS: The main administration route was "joints with tobacco"; other routes of administration had prevalence rates from 23.99% to 38.23%. In addition, increasing the number of administration routes was associated with more problematic cannabis use, as well as heavier illicit drug use. Water pipes without tobacco were especially linked to heavy drug use patterns, whereas "pure" cannabis use seemed less harmful. CONCLUSIONS: Our findings highlighted that diversification in routes of administration can be associated with heavier illicit drug use. This was especially true for water pipe users, whereas "pure" cannabis users, who did not mix cannabis with tobacco, were an exception. Indeed, these results may be useful for future preventive programs, which may need to focus on those who have diversified routes of administration for cannabis.

A Prevalence Study of Drug use by Young People in a Mixed Suburban Area

This report aims to determine the levels and patterns of drug use, including tobacco and alcohol, among young people in the Kilbarrack area. Questionnaires were sent to students from all primary and secondary schools in the target area, and were also sent to young people in the area who had already left school. The survey showed that 24% of respondents had smoked tobacco at some stage in their lives, with 25% listed as current smokers. Older students reported higher tobacco use, with over 40% of 16-18 year olds currently smoking. Alcohol was the drug most widely used by respondents, with 76% of all students having taken it at some stage in their lives. Prevalence of current alcohol use was higher in older children, with 84% of 16-18 year olds currently drinking as opposed to 61% of 13-15 year olds and 17% for 10 to 12 year olds. Cannabis was the most widely used illicit drug, with 37% of respondents using the drug at some stage. The next most widely used drug was inhalants, with 16% having used them at some stage, with 6% having used cocaine at some stage in their lives; the same proportion had used it within the last 12 months. There little or no significant evidence of heroin use. The report recommends prevention programmes that ensure that young people have other things in their lives other than alcohol/ drugs, such as a comprehensive range of properly resourced sporting and youth work in the community.This resource was contributed by The National Documentation Centre on Drug Use.

A Report from a Local Initiative Concerning Alcohol / Drug Use Among Teenagers 1998-1999

This study was carried out by participants in a North Tipperary Community Services drug/alcohol awareness course. Its objectives were to: assess the level of drug and alcohol awareness among second-level students under the age of 18 years; to find out the extent of under-age drinking;to find out the extent of the use of illegal substances as well as stimulants such as glue and solvents in this age group; and to use this information to develop educational programmes for parents and students. Date was obtained through a survey of 1500 secondary school students in the North Tippeary area. The survey found that, although ilict drug use was very low, abuse of alcohol was quite common.This resource was contributed by The National Documentation Centre on Drug Use.

A Survey of Poly-drug (Multiple-drug) Use Among Patients Receiving Methadone for the Treatment of their Opioid Addiction in the Northern Area Health Board

The objective of this study is to determine the extent of the problem of poly-drug (multiple-drug) use among patients receiving methadone. The study investigated levels and patterns of cocaine and cannabis use in opiate dependent patients receiving methadone treatment. This research also examines risks associated with injecting cocaine. A total number of 851 methadone patients receiving treatment for opiate related problems participated in the survey from a total number of 1082 patients receiving treatment in these clinics. This figure accounts for 80.1%. Participants reported the frequency and intensity of cocaine and cannabis use. Data collected showed that 42% of the methadone patients are using cannabis on a daily basis and that 77.47% had a history of cocaine use. The figure of cocaine use is an important indicator of the level and extent of cocaine use. It is valuable from a public health perspective to assess needs, and to plan and evaluate services. The survey concluded that cocaine abuse is emerging as a problem in the Irish drug sceneThis resource was contributed by The National Documentation Centre on Drug Use.

A Study of Tobacco, Alcohol and Drug Use among Irish Female Prisoners

The female prisoner population are a very specific group with very different needs to that of the general population. The study sets out to profile these women and to examine their use of tobacco, alcohol and other substances. A census sample of female prisoners was frequency matched for age with male prisoners and also the female general population. Response rate was 74.6%. Results illustrated that female prisoners are, in the majority from a lower social group, from deprived backgrounds and from families where unemployment is high and education is low. Female prisoners smoke more, take more drugs (including heroin and injection drugs) and drink considerably more when compared to the above groups. They have more alcohol related difficulties as a result of another persons drinking, illustrating high rates of verbal, physical and sexual assault. The prison setting may be the first and possibly the only opportunity for health education and promotion for this particular group. Therefore, with such high reported levels of smoking, alcohol and other substance use, the prison provides a good setting for health promotion interventions.This resource was contributed by The National Documentation Centre on Drug Use.

Indications of Public Health in the English Regions 10: Drug Use

This tenth in a series of national reports produced for the Chief Medical Officer (CMO) by the Association of Public Health Observatories (APHO) is on drug use. The report contains 46 different indicators of drug use relating to the individual, community and population across all nine English regions; with additional analysis of sub-regional inequalities where possible. An Executive Summary is also available.

Being old-for-grade and drug use: not such a clear connection.

AIM: To assess whether repeating a grade was associated with drug use among adolescents after controlling for personal, family and school-related variables, and whether there were differences between students in mandatory and post-mandatory school. METHODS: Data were drawn from the Catalonia Adolescent Health Survey, a cross-sectional study of in-school adolescents aged 14-19 y. The index group included 366 subjects who were repeating a grade at the time the survey was carried out (old-for-grade, OFG). A control group matched by gender, school and being one grade ahead was randomly chosen among all the subjects who had never repeated a grade. All statistically significant variables in the bivariate analysis were included in a multivariate analysis. In a second step, all analyses were repeated for students in mandatory (14-16 y) and post-mandatory (17-19 y) school. RESULTS: After controlling for background variables, subjects in the index group were more likely to perceive that most of their peers were using synthetic drugs and to have ever used them, to have bad grades and a worse relationship with their teachers. OFG students in mandatory school were more likely to have divorced parents, bad grades and have ever used synthetic drugs, whereas they were less likely to be regular drinkers. OFG students in post-mandatory school were more likely to have below average grades, to be regular smokers and to perceive that most of their peers used synthetic drugs. CONCLUSIONS: When background variables are taken into consideration, the relationship between repeating a grade and drug use is not so clear. By increasing the familial and academic support of adolescents with academic underachievement, we could reduce their drug consumption.

Orexin/hypocretin (Orx/Hcrt) transmission and drug-seeking behavior: is the paraventricular nucleus of the thalamus (PVT) part of the drug seeking circuitry?

The orexin/hypocretin (Orx/Hcrt) system has long been considered to regulate a wide range of physiological processes, including feeding, energy metabolism, and arousal. More recently, concordant observations have demonstrated an important role for these peptides in the reinforcing properties of most drugs of abuse. Orx/Hcrt neurons arise in the lateral hypothalamus (LH) and project to all brain structures implicated in the regulation of arousal, stress, and reward. Although Orx/Hcrt neurons have been shown to massively project to the paraventricular nucleus of the thalamus (PVT), only recent evidence suggested that the PVT may be a key relay of Orx/Hcrt-coded reward-related communication between the LH and both the ventral and dorsal striatum. While this thalamic region was not thought to be part of the "drug addiction circuitry," an increasing amount of evidence demonstrated that the PVT-particularly PVT Orx/Hcrt transmission-was implicated in the modulation of reward function in general and several aspects of drug-directed behaviors in particular. The present review discusses recent findings that suggest that maladaptive recruitment of PVT Orx/Hcrt signaling by drugs of abuse may promote persistent compulsive drug-seeking behavior following a period of protracted abstinence and as such may represent a relevant target for understanding the long-term vulnerability to drug relapse after withdrawal.

Association between non-medical prescription drug use and personality traits among young Swiss men.

AIM: To investigate the relationships between six classes of non-medical prescription drug use (NMPDU) and five personality traits. METHODS: Representative baseline data on 5777 Swiss men around 20 years old were taken from the Cohort Study on Substance Use Risk Factors. NMPDU of opioid analgesics, sedatives/sleeping pills, anxiolytics, antidepressants, beta-blockers and stimulants over the previous 12 months was measured. Personality was assessed using the Brief Sensation Seeking Scale; attention deficit-hyperactivity (ADH) using the Adult Attention-Deficit-Hyperactivity Disorder Self-Report Scale; and aggression/hostility, anxiety/neuroticism and sociability using the Zuckerman-Kuhlmann Personality Questionnaire. Logistic regression models for each personality trait were fitted, as were seven multiple logistic regression models predicting each NMPDU adjusting for all personality traits and covariates. RESULTS: Around 10.7% of participants reported NMPDU in the last 12 months, with opioid analgesics most prevalent (6.7%), then sedatives/sleeping pills (3.0%), anxiolytics (2.7%), and stimulants (1.9%). Sensation seeking (SS), ADH, aggression/hostility, and anxiety/neuroticism (but not sociability) were significantly positively associated with at least one drug class (OR varied between 1.24, 95%CI: 1.04-1.48 and 1.86, 95%CI: 1.47-2.35). Aggression/hostility, anxiety/neuroticism and ADH were significantly and positively related to almost all NMPDU. Sociability was inversely related to NMPDU of sedatives/sleeping pills and anxiolytics (OR, 0.70; 95%CI: 0.51-0.96 and OR, 0.64; 95%CI: 0.46-0.90, respectively). SS was related only to stimulant use (OR, 1.74; 95%CI: 1.14-2.65). CONCLUSION: People with higher scores for ADH, aggression/hostility and anxiety/neuroticism are at higher risk of NMPDU. Sociability appeared to protect from NMPDU of sedatives/sleeping pills and anxiolytics.

Non-medical prescription drug and illicit street drug use among young Swiss men and associated mental health issues.

Non-medical use of prescription drugs (NMUPD) is increasing among the general population, particularly among teenagers and young adults. Although prescription drugs are considered safer than illicit street drugs, NMUPD can lead to detrimental consequences. The aim of the present study was to investigate the relationship between drug use (NMUPD on the one side, illicit street drugs on the other side) with mental health issues and then compare these associations. A representative sample of 5719 young Swiss men aged around 20 years filled in a questionnaire as part of the ongoing baseline Cohort Study on Substance Use Risk Factors (C-SURF). Drug use (16 illicit street drugs and 5 NMUPDs, including sleeping pills, sedatives, pain killers, antidepressants, stimulants) and mental health issues (depression, SF12) were assessed. Simple and multiple linear regressions were employed. In simple regressions, all illicit and prescription drugs were associated with poorer mental health. In multiple regressions, most of the NMUPDs, except for stimulants, were significantly associated with poorer mental health and with depression. On the contrary, the only associations that remained significant between illicit street drugs and mental health involved cannabis. NMUPD is of growing concern not only because of its increasing occurrence, but also because of its association with depression and mental health problems, which is stronger than the association observed between these problems and illicit street drug use, excepted for cannabis. Therefore, NMUPD must be considered in screening for substance use prevention purposes.
