Being stoned: a review of self-reported cannabis effects.

Abstract: Although there has been considerable research into the adverse effects of cannabis, less attention has been directed toward subjective effects that may be associated with ongoing cannabis use. Examination of self-reported cannabis effects is an important issue in understanding the widespread use of cannabis. While reviews have identified euphoria as a primary factor in maintaining cannabis use, relaxation is the effect reported most commonly in naturalistic studies of cannabis users, irrespective of the method used. Self-reported effects in 12 naturalistic and 18 laboratory studies were compared. Regardless of methodology there was considerable variation in the effects experienced. Variation has been reported in terms of opposite effects being experienced by different individuals, variation of effects by individuals within a single occasion and between occasions of use. Factors that might explain this variation are outlined. Limitations of the available literature and suggested directions for future research are discussed.

A prototype screening instrument for cannabis use disorder: the Cannabis Use Disorders Identification Test (CUDIT) in an alcohol-dependent clinical sample.

Abstract: The Cannabis Use Disorders Identification Test (CUDIT) was used for the first time as part of a randomized controlled trial for brief interventions in mild to moderate alcohol-dependent out-patients. This sample may be seen as a population at increased risk of cannabis use disorder. The CUDIT was developed by modifying the Alcohol Use Disorders Identification Test (AUDIT). The ability of the CUDIT to accurately screen for cannabis abuse or dependence was examined in the portion of the sample who reported some cannabis use over the preceding 6 months (n=53), as was self-reported frequency of cannabis use in the preceding 6 months. The CUDIT was superior to the frequency measure, achieving positive predictive power of 84.6% and sensitivity of 73.3% at a cut-off of 8, compared to positive predictive power of 81.8% and sensitivity of 60.0% for 80 or more cannabis use-days. These results indicate the viability of a screening measure for identifying cannabis use disorder in at risk populations.

Review of bupropion for smoking cessation

Abstract: The advent of bupropion hydrochloride sustained release (Zyban) has heralded a major change in the options available for smoking cessation pharmacotherapy. Bupropion is a selective re-uptake inhibitor of dopamine and noradrenalin which prevents or reduces cravings and other features of nicotine withdrawal. Bupropion is a useful oral and non-nicotine form of pharmacotherapy for smoking cessation. For this review a total of 221 papers were reviewed plus poster presentations. This review examines in detail original clinical trials on efficacy, categorised according to whether they were acute treatment trials in healthy smokers; studies in specific populations such as people with depression, chronic obstructive pulmonary disease (COPD) or cardiovascular disease; or relapse prevention studies. Overall, these studies in varying populations comprising over four thousand subjects, showed bupropion consistently produces a positive effect on smoking cessation outcomes. The evidence highlights the major public health role that bupropion has in smoking cessation. The methodological issues of published clinical trials reporting one year outcomes were examined in detail including: completeness of follow-up; loss to follow-up; intention to treat analysis; blindness of assessment; and validation of smoking status. The review discusses contraindications, adverse effects, dose and overdose, addictive potential, and the role of bupropion in reducing cessation-related weight gain. Bupropion combined with or compared to other pharmacotherapies (nicotine patch; nortriptyline) is considered. Impressive evidence exists for the use of bupropion in smoking cessation among difficult patients who are hard-core smokers such as those with cardiovascular disease, chronic obstructive pulmonary disease (COPD) and depression. Bupropion reduces withdrawal symptoms as well as weight gain and is effective for smoking cessation for people with and without a history of depression or alcoholism. Serious side effects of bupropion use are rare. The major safety issue with bupropion is risk of seizures (estimated at approximately 0.1%) and it should not be prescribed to patients with a current seizure disorder or any history of seizures. In clinical trials of bupropion for smoking cessation no seizures were reported. Allergic reactions occur at a rate of approximately 3% and minor adverse effects are common including dry mouth and insomnia.

A systematic review of the effectiveness of brief interventions with substance using adolescents by type of drug.

Abstract: The aim of this paper is to evaluate the effectiveness of brief interventions (BI) with adolescents (mean age <20) in reducing alcohol, tobacco or other drug (ATOD) use by means of a systematic review of BI for adolescent substance use in the English language literature up to 2002. We identified 11 studies involving 3734 adolescents. Follow-up ranged from 6 weeks to 24 months. Motivational interviewing was the predominant approach, underpinning eight studies: the remaining three provided personalized health information. Seven papers reported outcomes for alcohol interventions and four involved other substances (including one with separate alcohol outcomes). The overall effect size was d=0.126 with borderline homogeneity (Q=14.9, df=9, p=0.09). The effect size from the eight alcohol interventions (n=1,075) was classified as significant but "small" (d=0.275). The remaining non-alcohol studies were considered separately as interventions involving tobacco or multiple substance use. The two interventions with tobacco involved a substantial sample (n=2,626) but had a very small effect (d=0.037), while the two interventions addressing multiple substances involved few participants (n=110) but had a medium-large effect (d=0.78). Across a diverse range of settings (dental clinic, schools, universities, substance treatment centres) and, therefore, probably diverse clients, BI conferred benefits to adolescent substance users. BI had a small effect on alcohol consumption and related measures. The data for tobacco interventions suggested a very small reduction, particularly with general community interventions. The effect of BI with multiple substances appears substantial but the small sample cautions against expansive generalization.

Drug consumption facilities: an update since 2000.

Abstract: The topic of drug consumption facilities or rooms (DCRs) was reviewed by Dolan, Kimber and others in Harm Reduction Digest 10, published in the September 2000 issue of DAR. As one of the first English language papers on the topic this paper has been cited extensively. Now, 3 years on, these authors and have brought together an international team of experts to revisit the topic. In this update they: (i) highlight where DCRs are operating or under consideration, (ii) review briefly new literature and (iii) discuss future directions. This Digest is a 'must read' for policy makers, advocates and practitioners in the drug field.

Obstacles to carrying out brief intervention for heavy drinkers in primary health care: a focus group study.

Abstract: The objective of this study was to identify possible obstacles to carrying out competent early identification and brief intervention (EIBI) of heavy drinkers in primary health care. Qualitative focus group discussion method study applying the deductive framework approach. Six focus groups involving 18 general practitioners and 19 nurses were recruited from primary health care of the City of Tampere, Finland. Possible obstacles are: (1) confusion regarding the content of early-phase heavy drinking, (2) lack of self-efficacy among primary health care professionals, (3) sense of lacking time needed for carrying out brief intervention, (4) not having simple guidelines for brief intervention, (5) sense of difficulty in identifying of early-phase heavy drinkers, and (6) uncertainty about the justification for initiating discussion on alcohol issues with patients. The main actions to be taken to promote brief intervention are to educate professionals about the content of early-phase heavy drinking and to produce directing, but not excessively demanding guidelines for carrying out EIBI. Probably successful personal experiences carrying out EIBI can improve professionals' self-efficacy and give to them final justification for discussion alcohol issues with their patients.

Hepatitis C-related discrimination among heroin users in Sydney: drug user or hepatitis C discrimination?

Abstract: The hepatitis C virus (HCV) is a common infection among injecting drug users. There are currently few available data on the extent (or prevalence) of HCV-related discrimination. This study examined perceived discrimination among a sample of heroin users and sought to determine whether the discrimination was attributed to their drug user or HCV status. Heroin users were recruited through needle and syringe programmes and methadone clinics in Sydney and were asked about discrimination in the preceding 12 months. Four hundred and one heroin users were recruited, of whom 59% reported being HCV-positive. Discrimination was reported by 22% of the 237 IDUs who reported being HCV-positive, with 17% reporting that the discrimination occurred in the preceding 12 months. Sixty-seven incidents were reported, of which half were perceived to be due to their drug user status, 15% of these incidents were due to HCV status and 25% due to a combination of both. Twenty-five incidents occurred in a health-care setting, of wh...

Patterns of co-morbidity between alcohol use and other substance use in the Australian population

Abstract: The present study describes patterns of co-morbidity between alcohol use and other substance use problems in the Australian population using data from the 1997 National Survey of Mental Health and Well-Being. Multiple regression analyses examined whether the observed associations between alcohol and other drug use disorders were explained by other variables, including demographic characteristics and neuroticism. We also assessed whether the presence of co-morbid substance use disorders affected treatment seeking for a mental health problem. Alcohol use was related strongly to the use of other substances. Those who did not report alcohol use within the past 12 months were less likely to report using tobacco, cannabis, sedatives, stimulants or opiates. Higher rates again were observed among those with alcohol use disorders: half (51%) of those who were alcohol-dependent were regular tobacco smokers, one-third had used cannabis (32%); 15% reported other drug use; 15% met criteria for a cannabis use disorder and 7% met criteria for another drug use disorder. These associations were not accounted for by the demographic and other variables considered here. Co-morbid substance use disorders (sedatives, stimulants or opioids) predicted a high likelihood of seeking treatment for a mental health problem among alcohol-dependent people.

Improving family functioning and child outcome in methadone maintained families: the Parents Under Pressure programme

Abstract: Twelve families responded to posters displayed in a methadone clinic for inclusion in a pilot study assessing the viability and potential utility of an intensive, multi-component family-focused intervention, the Parents Under Pressure programme. The programme was designed to improve child behaviour, decrease parental stress and improve family functioning in methadone-maintained families by targeting affect regulation, mood, views of self as a parent, drug use and parenting skills. Nine of the families completed the programme delivered in their homes; eight were recontacted at 3 months. Each family reported significant improvements in three domains: parental functioning, parent-child relationship and parental substance use and risk behaviour. In addition to the changes in family functioning, the majority of families reported a decrease in concurrent alcohol use, HIV risk-taking behaviour and maintenance dose of methadone. The families reported high levels of satisfaction with the programme. It is recommended that future studies include independent measures (e.g. behavioural observations) of child outcome and parental functioning. The results were optimistic and provided the impetus to evaluate the treatment programme using a randomized controlled trial.

Smoking intervention within alcohol and other drug treatment services: a selective review with suggestions for practical management

Abstract: This selective review was undertaken in order to highlight the need for alcohol and other drug treatment services to provide intervention for tobacco smoking to their clients. The reasons for the failure of treatment services to date to deal with nicotine addiction within their programmes are discussed and positive suggestions for change are proferred. In addition to the transformation of institutional culture which will be required, managers and staff of alcohol and other drug agencies need to know how best to implement smoking intervention within the treatment setting. The paper concludes with some practical suggestions for the management of intervention for tobacco smoking within treatment settings. These suggestions include: making decisions and formulating policies and procedures with regard to how tobacco smoking will be addressed; considering the particular physical, psychological and social/environmental factors that apply to substance abuse clients; building intervention around a simple structure such as the '5 A's'; encouraging and facilitating the use of nicotine replacement therapies; and allowing flexibility to tailor intervention to the individual. A great deal of further research is required to inform us as to how to intervene most effectively for tobacco smoking among this population group.

Comparison of disulfiram and placebo in treatment of alcohol dependence of adolescents.

Abstract: About 50% of alcoholic patients relapse within 3 months of treatment. Previous studies have suggested that disulfiram may help to prevent such relapse. The aim of our study was to assess the efficacy and safety of long-term disulfiram treatment in alcohol dependence of adolescents. In this double-blind, placebo-controlled study we recruited 26 adolescents, aged 16-19 years, with chronic or episodic alcohol dependence. Patients were allocated treatment randomly with disulfiram (200 mg daily) or placebo for 90 days. Patients were assessed on the day treatment started and on days 30 and 90 by interview, self-report, questionnaire and laboratory screening. Patients were classified as abstinent, relapsing or non-attending. Time to first treatment failure (relapse or non-attendance) was the primary outcome measure. The disulfiram (n=13) and placebo (n=13) groups were well matched in terms of baseline demographic and alcohol-related variables. Thirteen disulfiram-treated and 13 placebo-treated patients completed the treatment phase; seven (1 vs. 6) relapsed, five (3 vs. 2) refused to continue treatment, three (1 vs. 2) had concurrent illness and two (1 vs. 1) had adverse side effects. At the end of treatment, seven disulfiram-treated and two placebo-treated patients had been abstinent continuously (p=0.0063). Mean cumulative abstinence duration was significantly greater in the disulfiram group than in the placebo group [68.5 (SD 37.5) vs. 29.7 (19.0) days; p=0.012]. Apart from occasional diarrhoea, there was no difference in side effects between groups. In some cases, disulfiram may be an effective and well-tolerated pharmacological adjunct to psychosocial and behavioural treatment programmes for treatment of adolescent alcohol-dependent patients.

Pharmacotherapies to enhance smoking cessation during pregnancy

Abstract: Smoking during pregnancy is a significant public health concern. Maternal smoking increases the risk of spontaneous abortion, low birth weight, premature delivery, sudden infant death syndrome and learning and behavioral problems in the offspring. Unfortunately, the majority of pregnant women do not quit smoking during pregnancy. Although pharmacotherapy may improve smoking cessation rates in pregnancy, very few studies exist that have studied the safety and efficacy of medications to treat pregnant smokers. This article reviews the available safety and efficacy data for the use in pregnancy of the five first-line therapies and two second-line therapies that are recommended for smoking cessation in non-pregnant smokers. Other promising nicotine replacement therapies are also reviewed. Ultimately, the choice whether to use pharmacotherapy for smoking cessation should be made jointly by the pregnant smoker and her health care provider. This article reviews factors that may be considered when prescribing pharmacotherapy to pregnant smokers (i.e. the role of behavioral counseling, identification of appropriate patients, potential advantages and disadvantages of each of the pharmacotherapies, proposed monitoring strategies, dose and duration and goals of treatment). More research regarding the safety and efficacy of pharmacotherapy during pregnancy is needed to define the risk/benefit profile of each medication for use in smoking cessation in pregnant women.

Smoking cessation interventions for in-patients: a selective review with recommendations for hospital-based health professionals.

Abstract: A selective review of the literature was conducted to provide evidence-based recommendations for the clinical management of hospitalized smokers. The Cochrane library, in particular the Cochrane review of ‘Interventions for smoking cessation in hospitalised patients’, was the basis for the review and was supplemented with other clinical and non-clinical literature where the review did not inform clinicians sufficiently. Evidence was reviewed on issues considered by the authors to be of importance to health professionals interested in providing a smoking cessation intervention to their patients. The review suggests that effective hospital interventions: incorporate an in-patient intervention lasting greater than 20 minutes in duration with extended post discharge follow-up; consist of at least five intervention contacts; and be delivered over at least a 3-month period. Furthermore, interventions should include in-patient advice and counselling, the provision of nicotine replacement therapy and extended pro...

Aftercare attendance and post-treatment functioning of severely substance dependent residential treatment clients.

Abstract: The present study evaluated the impact of a structured aftercare programme following residential treatment for severe alcohol and/or heroin dependent clients. Over 17 months, 77 participants were recruited to the study and allocated randomly to either a structured aftercare (SA) programme or to unstructured aftercare (UA) of crisis counselling on request. Independent clinicians interviewed participants and collaterals, at 4-month (median) intervals, for 12 months following residential treatment. SA compared to UA was associated with a fourfold increase in aftercare attendance and one-third the rate of uncontrolled principal substance use at follow-up. Participants who attended either type of aftercare relapsed a median of 134 days later than those who attended no aftercare. Overall, 23% of monitored participants remained abstinent throughout, 21% maintained controlled substance use and 56% relapsed, within a median of 36 days following residential treatment. The only significant predictor of days to relapse, controlling for age, was pretreatment use of additional substances. Participants with pretreatment additional substance use relapsed a median of 192 days earlier than those who had used no other substances. The degree of agreement between participant self-reports and collateral reports was fair-to-moderate and moderate among collaterals. Intention-to-treat analyses revealed significant and clinically meaningful reductions in substance use in this sample of severely dependent residential treatment clients. The generalizability of these results is limited because of significant differences in age and presenting substance between the study sample and other clients admitted to the service during the study. This latter group of younger, male, heroin-dependent clients with polydrug use who refuse opioid pharmacotherapy, are more likely to drop out of treatment or relapse early following treatment and continue to present a challenge to treatment services.

Development of a structured generic drug intervention model for public health purposes: a brief application of motivational interviewing with young people.

Abstract: Brief applications of Motivational Interviewing (MI) emerged around 15 years ago to target problematic alcohol and other drug use. Interventions which specifically target illicit drug use, young people, or which are delivered in settings other than health-care services have, however, been relatively slow to develop. The needs of young people for interventions distinct from those offered to adults are considered, as a precursor to an outline of the structure of a newly adapted intervention targeting drug use in general among young people. Based upon earlier topic-based approaches developed by Rollnick et al. this intervention is innovative in simultaneously targeting a range of drugs in pursuit of secondary prevention objectives, while also seeking to manifest the spirit of MI. The intervention consists of a single-session face-to-face conversation of up to 60 minutes duration. Data are presented which describe the development and conduct of this intervention during the course of an efficacy trial, with promising efficacy data themselves reported elsewhere. Observations are made on intervention delivery and consideration is given to implications for further novel targeting of young people and within the field of addiction interventions more generally.

The monitoring of drug trends in Australia.

Abstract: Recently, there has been increased recognition of the importance of drug information systems (DIS), highlighting the need for an internationally coordinated approach to data collection and advocating the regular assessment of a range of areas. Accurate information provides policy makers with the evidence to evaluate current strategies and to plan future strategies. An effective drug information system (DIS) must collect comprehensive, detailed and in-depth data, while also being sensitive to emergent trends and placing these changes into the context of longer-term trends. An integrated and comprehensive system combines both sensitive (or lead) and slower but more reliable lag indicators. This article reviews conceptual frameworks for DIS and developments in international systems. It then considers the range of DIS in Australia and then describes two integrated monitoring systems with an early warning function: the Illicit Drug Reporting System (IDRS) and the Drug Use Monitoring Australia (DUMA) Programme. Both systems collate sensitive lead indicators, and provide timely information about emerging drug trends in Australia. Together, these two systems are best-placed to provide effective early warning of new trends in illicit drug markets, and constitute an important component of the overall approach to the monitoring of drug use and associated harms in Australia.

Similarities in outcomes for men and women after drug misuse treatment: results from the National Treatment Outcome Research Study (NTORS).

Abstract: The National Treatment Outcome Research Study (NTORS) is a prospective, multi-site treatment outcome study of drug misusers in the UK. This paper reports the characteristics and problems of male and female clients at intake to treatment, and changes in substance use, health problems, and criminal behaviour at follow-up. The sample comprised 753 subjects (552 men and 201 women) followed-up 1 year after starting treatment in 54 programmes chosen to be representative of the main national treatment modalities. Men and women presented to treatment with different problems and characteristics. Women reported more frequent cocaine use, greater health problems, and were more likely to have a drug-using partner and be responsible for children. Despite different profiles of problems, men and women both made significant reductions in their problem behaviours following treatment. At 1-year follow-up, men and women reported reductions in drug use, health problems and criminal behaviour. However, women did not reduce their alcohol consumption significantly, and improvements in crime were less pronounced than for men. After controlling for pretreatment differences, gender was not predictive of any of the outcome measures reported.

Family risk factors for cannabis use: a population-based survey of Australian secondary school students.

Abstract: The objective of this study was to investigate relationships between adolescent cannabis use and indices of parent - child attachment, family functioning and parent attitudes to drugs and delinquency. A total of 2848 year 9 and 2363 year 11 students participated in the Victorian Adolescent Health and Well-Being Survey (1999). The study was a school-based random sample of 535 metropolitan and rural, government and non-government secondary schools throughout Victoria, Australia. Cannabis use was defined as 'any' and 'weekly' use in the last 30 days. Multivariate logistic regression was used to identify independent associations between cannabis use and parent - child attachment, family functioning and parent attitudes to drugs and delinquency. Cannabis use in year 9 was associated with permissive parent attitudes to drugs and delinquency (any use: adjusted odds ratio (OR) = 8.1; weekly use: adjusted OR = 7.6), and was particularly sensitive to small changes in the quality of the parent - child relationship with risk increasing threefold for those describing their attachment as 'good' compared with 'very good' (any use: adjusted OR = 2.8, weekly use adjusted OR = 2.9). A similar, but more moderate pattern association was evident in year 11. After adjusting for other family and background factors, poor family functioning showed minimal association with level of cannabis use at both year levels. Results suggest that intervention efforts might sensibly target strengthening parent - children relationships and promoting less permissive parent attitudes to drug use.

Problematic alcohol and cannabis use in adolescence—risk of serious adult substance abuse?

Abstract: The aim of this longitudinal study was to investigate the problematic use of alcohol, cannabis or both in adolescence, identifying various risk factors for adult alcohol and drug abuse. The study included 7577 18-year-old men conscripted in 1969 – 70. At enrolment, they completed two questionnaires about alcohol and drug use, social background, behavioural factors and health conditions. Data on adult alcohol and substance abuse were obtained from official registers up to 1996. A combination of problematic alcohol use and cannabis use in adolescence ( > 10 times) was associated more strongly with both adult alcohol abuse (RR = 6.56, 95% CI 4.24 – 9.83) and drug abuse (RR = 19.37, 95% CI 11.16 – 32.30) than adolescent use of cannabis or alcohol alone. When stratifying for different risk factors, the combination of both problematic alcohol use and cannabis use had higher relative risks of both outcomes than alcohol or cannabis use alone. In multivariate analyses, tobacco smoking was associated most strongly ...

In-patient benzodiazepine withdrawal: comparison of fixed and symptom-triggered taper methods.

Abstract: Fixed and symptom-triggered taper methods during in-patient benzodiazepine withdrawal treatment were compared using a randomized controlled design. Forty-four benzodiazepine users seeking in-patient withdrawal treatment at two substance use treatment clinics in Adelaide, Australia were recruited. Measurements included the Severity of Dependence Scale and the SF-36. A scale comprising six items from the Clinical Institute Withdrawal Assessment Scale--Benzodiazepines (CIWA-B) was used to measure withdrawal symptoms. Participants were randomized to receive a fixed diazepam tapering regime or diazepam only in response to withdrawal symptoms (symptom-triggered group). Results showed that there were no significant differences between treatment groups in terms of withdrawal severity, duration of in-patient treatment, amount of diazepam administered, treatment attrition and benzodiazepine use at follow-up. Both groups showed a reduction in benzodiazepine dosage of 86% over the first 8 days which was maintained at 1 month post-discharge. Although there were improvements in some subscales of the SF-36 between baseline and follow-up, values were significantly below age-matched norms at both time-points. This study showed that benzodiazepine users entering treatment have relatively poor health and that symptom-triggered taper methods incorporating flexible dosing and flexible treatment duration are as effective as fixed dose taper methods for in-patient benzodiazepine withdrawal treatment.

General practitioners' diagnostic skills and referral practices in managing patients with drug and alcohol-related health problems: implications for medical training and education programmes

Abstract: The aim of this study was to determine the current practices of established general practitioners in managing patients with drug and alcohol-related problems and identify gaps in training. A random sample of general practitioners completed a survey assessing diagnostic skills and referral practices concerning alcohol and illicit drug use in general practices in February 1999, comprising 110 general practitioners registered with the Central Sydney Division of General Practice. The main outcome measures were competent skills and knowledge, willingness to treat. The majority (96%) of GPs provided clinically appropriate responses for at least one drug category, although none received this rating for all six. Most general practitioners reported that they were unwilling to treat heroin and cocaine problems themselves but expressed willingness to refer patients appropriately. More than a quarter of general practitioners were unaware of the safe drinking levels for men and women or the appropriate treatment for patients consuming above such levels. Age, years in practice, type of practice, willingness to obtain drug use histories and post-graduate training were all significantly associated with general practitioners' willingness to treat and competence in managing drug and alcohol-related problems. In this study, general practioners reported low levels of skills and referrals for treatment of illicit drug use and suboptimal skills in the management of alcohol problems. The results suggest that a more comprehensive approach to education and training is required to bring about a change in practice behaviour. [Fucito LM, Gomes BS, Murnion B, Haber PS. General practitioners' diagnostic skills and referral practices in managing patients with drug and alcohol-related health problems: implications for medical training and education programmes.

A review of psychosocial interventions for amphetamine use.

Abstract: There are clear signs that amphetamine use is increasing in Australia and internationally, yet there are few services that offer amphetamine-specific interventions. This review examines the evidence for the use of psychosocial interventions for amphetamine users. The literature is very limited in the number of well-conducted, controlled studies, but the evidence available suggests that cognitive-behavioural therapy appears to be current best practice. Motivational interviewing has been recommended as a strategy to assist those ambivalent for treatment. There is also some evidence that contingency management is effective while clients are in treatment. The effectiveness of other types of intervention is not well supported. The literature is particularly hindered by a paucity of well-conducted studies among primary amphetamine users. Recommendations about appropriate interventions for use in clinical settings are offered and directions for future research are considered.

Alcohol and other drug use disorders among older-aged people.

Abstract: In Australia people aged 65 years or older currently comprise 12.1% of the population. This has been estimated to rise to 24.2% by 2051. Until recently there has been relatively little research on alcohol and other drug use disorders among these individuals but, given the ageing population, this issue is likely to become of increasing importance and prominence. Epidemiological research shows a strong age-related decline in the prevalence of alcohol and other drug use disorders with age. Possible reasons for this include: age-related declines in the use and misuse of alcohol and other drugs; increased mortality among those with a lifetime history of alcohol and other drug use disorders; historical differences in exposure to and use of alcohol and other drugs. Despite the age-related decline in the prevalence of these disorders, they do still occur among those aged 65 years or older and, given historical changes in exposure to and use of illicit drugs, it likely that the prevalence of these disorders among older-aged individuals will rise. Specific issues faced by older-aged individuals with alcohol and other drug use problems are discussed. These include: interactions with prescribed medications, under-recognition and treatment of alcohol and drug problems, unintentional injury and social isolation. Finally, a brief discussion of treatment issues is provided.

Substance use and the prediction of young offender recidivism

Abstract: The problem considered is whether self-reported substance use can be used in the estimation of recidivism risk among youths placed in secure care. The Secure Care Psychosocial Screening (SECAPS) and offending records of 447 youths admitted to detention centres in South Australia were examined. The target outcome was any new offending within 6 months of release. Use of a psychoactive substance at the time of committing the most recent offence was not a significant predictor of subsequent offending, nor was acknowledging having a problem with drug or alcohol use. In relation to the recent use of alcohol, marijuana, hallucinogens, sedatives/hypnotics, narcotics, stimulants and inhalants, only the use of alcohol and inhalants appeared to have significant relationships with recidivism. While the relationships were too small to permit using these items on their own to estimate re-offending risk, recent alcohol and inhalant use could be included as part of a broader recidivism risk assessment.

Adolescent alcohol-use trajectories in the transition from high school.

Abstract: A cohort of 3300 students from high schools across Victoria, Australia, were surveyed regarding their patterns of alcohol consumption from mid-1993 to 1995. The first wave of data was collected halfway through the students' final year of school (year 12). Students were then resurveyed 3 months following school completion and on two subsequent occasions, each separated by 6-month intervals. Analysis of the four waves of data indicated that five longitudinal patterns (trajectories) characterized temporal trends in male and female alcohol use through the transition from high school. Stable non-use trajectories were evident for 17% of males and 16% of females. Trajectories of less than weekly use characterized 45% of females and 46% of males, and showed little tendency to escalate toward harmful use. Among those using alcohol on a weekly or more frequent basis in high school, with few exceptions, use continued with at least the same frequency, but the quantity of alcohol consumed tended to escalate over time toward harmful levels. Overall, findings indicate that patterns of alcohol use tend to be stable over time, and more frequent alcohol use during the final year of high school tends to precede potentially harmful alcohol use following high school. Encouraging those high school students who consume alcohol once per week or more often to use alcohol on a less than weekly basis may be a valuable yet neglected harm minimization strategy.

Update: comparison of drug use in Australia and the United States as seen in the 2001 National Household Surveys

Abstract: This paper updates an earlier article by comparing the results of the 1998 and 2001 household surveys. The Australian survey showed a significant decrease in past-year use of “any illicit drug”. The methodological changes in the US surveys prevented comparison for these years, but there were increases in use of any illicit drug between 2000 and 2001. Patterns of use of marijuana, stimulants, cocaine, ecstasy, heroin and needles are shown by age group and gender. Use by teenage girls in both countries has risen to the point that they are now using alcohol and some drugs at rates similar to boys. Over 20% of teens in both countries reported binge drinking in the past month. While Australians in their 20s had the highest rates of lifetime and past-year use, in the United States, depending on the drug, lifetime use was highest among people in their 30s or 40s, with past-year use highest among teenagers. Drug treatment services are needed not only for young people, but also for aging users. The changes in perc...

Health and well-being outcomes for drug-dependent offenders on the NSW Drug Court programme.

Abstract: Given the centrality of drug treatment to the drug court framework, the proliferation of drug courts in the United States, and their emergence more recently in Australia, it is surprising that such little attention has been given to assessing their therapeutic effect. This evaluation aimed to assess the health and well-being of drug-dependent offenders diverted to the New South Wales Drug Court, and monitor changes in their health and well-being throughout 12 months of programme participation. The study consisted of baseline interviews with 202 offenders accepted into the programme between February 1999 and April 2000, and follow-up interview at 4, 8 and 12 months with participants who remained on the programme. Health and well-being was assessed at each follow-up using the Short Form-36 Health Survey (SF-36) the OTI social functioning scale, and self-reported spending as a proxy for illicit drug use. The health of male Drug Court participants prior to commencing the programme was significantly poorer than Australian population norms. The results provided evidence of significant and sustained improvements in health and well-being for the 51 participants who competed each follow-up interview. Furthermore, significant improvements were found for offenders who remained on the programme for at least 4 months but less than 12 months. However, the positive health outcomes are limited by the low programme retention rate. These results indicate that significant health outcomes can be achieved for at least some heavily drug-dependent, recidivist offenders through the drug court model.

The relationship of conduct disorder to attempted suicide and drug use history among methadone maintenance patients

Abstract: In order to examine the effects of a diagnosis of childhood conduct disorder (CD) on history of attempted suicide and drug use, unconfounded by early onset heroin use, 181 methadone maintenance patients who commenced heroin use after the age of 15 were interviewed. CD was diagnosed in 54% of patients. Compared to other patients, CD patients were younger and less educated. The onset of drug use, injecting drug use and heroin use occurred, on average, 2 years earlier than in other patients, and they had broader histories of injecting polydrug use. CD patients were more likely to have attempted suicide and to have been hospitalized after an attempt, and to have attempted suicide while enrolled in their current treatment. The current study indicates that a history of CD increases the risk of attempted suicide over and above the higher risks associated with injecting drug use per se.

Patterns and correlates of substance use amongst juvenile detainees in New South Wales 1989-99.

Abstract: In the decade 1989 - 99 there have been significant changes in the patterns of substance use in the Australian community. Juvenile offenders have been a sentinel population of these emerging trends. The social and personal costs associated with adolescent substance use, especially where it leads to increased criminal offending requires urgent attention. This study was a replication of the 1989 and 1994 surveys of young people in detention in New South Wales, Australia. The 300 voluntary participants from nine detention centres had a similar demographic profile to participants of the previous surveys. They were predominantly male (90%) with a mean age of 16.5 years and an over-representation of Aboriginal and Torres Straits Islander peoples. The patterns of lifetime alcohol and tobacco use were stable over the decade, with particular increases in amphetamine, opioid and cocaine use since 1994. The more concerning pattern of at least weekly substance use revealed significant increases in cannabis, opioid an...
