Multiply disadvantaged: Health and service utilisation factors faced by homeless injecting drug consumers in Australia

INTRODUCTION AND AIMS Homelessness status is strongly correlated with higher rates of substance use. Few studies, however, examine the complex relationship between housing status and substance use in people who inject drugs (PWID). This study extends previous research by comparing the physical and mental health status and service utilisation rates between stably housed and homeless PWID. DESIGN AND METHODS A cross-sectional sample of 923 PWID were recruited for the 2012 Illicit Drug Reporting System. Multivariate models were generated addressing associations between homelessness and the domains of demographics; substance use; and health status, service utilisation and criminal justice system contact, with significant correlates entered into a final multivariate model. RESULTS Two-thirds of the PWID sample were male. The median age was 39 years and 16% identified as Indigenous. Almost one-quarter (23%) reported that they were homeless. Homeless PWID were significantly more likely to be unemployed [adjusted odds ratio (AOR) 2.83, 95% confidence interval (CI) 1.26, 6.34], inject in public (AOR 2.01, 95% CI 1.38, 3.18), have poorer mental health (AOR 0.98, 95% CI 0.97, 1.00), report schizophrenia (AOR 2.31, 95% CI 1.16, 4.60) and have a prison history (AOR 1.53, 95% CI 1.05, 2.21) than stably housed PWID. DISCUSSION AND CONCLUSIONS Findings highlight the challenge of mental health problems for homeless PWID. Our results demonstrate that further research that evaluates outcomes of housing programs accommodating PWID, particularly those with comorbid mental health disorders, is warranted. Results also emphasise the need to better utilise integrated models of outreach care that co-manage housing and mental health needs.

Treating Comorbid Substance Use and Traumatic Stress among Male Prisoners: A Pilot Study of the Acceptability, Feasibility, and Preliminary Efficacy of Seeking Safety

Co-occurring substance use disorder and posttraumatic stress disorder is prevalent among prisoners, however there are few evidence-based treatment options available for this population. This pilot study investigated the acceptability, feasibility and preliminary efficacy of implementing partial-dose (eight-session) Seeking Safety among 30 Australian male prisoners. Findings demonstrate that Seeking Safety is desirable, acceptable, and feasible among male prisoners with a history of substance use and trauma. In addition, the study indicated promising results for substance use and mental health outcomes, which is particularly notable given the overall severity of the sample. The study also had significant Aboriginal and/or Torres Strait Islander representation. A full scale trial of this intervention is required to further evaluate efficacy and inform practice to improve the mental health of this vulnerable population.

Motivations, substance use and other correlates amongst property and violent offenders who regularly inject drugs.

OBJECTIVE To examine the prevalence, correlates and motivations for the commission of property and violent crime amongst a sample of people who inject drugs (PWID). METHOD Data were obtained from the 2013 Illicit Drug Reporting System (IDRS), which includes a cross-sectional sample of 887 PWID. RESULTS Eighteen percent of PWID had committed a property offence and 3% had committed a violent offence in the month preceding interview. Opioid dependence (AOR 2.57, 95% CI 1.29-5.10) and age (AOR 0.96, 95% CI 0.93-0.99) were found to be the strongest correlates of property crime. The majority of property offenders (75%) attributed their offending to financial reasons, however those under the influence of benzodiazepines were proportionately more likely to nominate opportunistic reasons as the main motivation for their last offence. Stimulant dependence (AOR 5.34, 95% CI 1.91-14.93) was the only significant correlate of past month violent crime, and the largest proportion of violent offenders (47%) attributed their offending to opportunistic reasons. The majority of both property (71%) and violent offenders (73%) reported being under the influence of drugs the last time they committed an offence; the largest proportion of property offenders reported being under the influence of benzodiazepines (29%) and methamphetamine (24%), whilst violent offenders mostly reported being under the influence of heroin and alcohol (32% respectively). CONCLUSION Criminal motivations, substance use and other correlates vary considerably across crime types. This suggests that crime prevention and intervention strategies need to be tailored according to individual crime types, and should take into account self-reported criminal motivations, as well as specific risk factors that have been shown to increase the likelihood of offending.

Co-ingestion of energy drinks with alcohol and other substances among a sample of people who regularly use ecstasy

INTRODUCTION AND AIMS Despite the potential harms of mixing unregulated drugs with energy drinks (ED), research to date has primarily been focused on EDs co-ingested with alcohol. Consequently, the aim of the present study was to explore the rate of use, harms and correlates of EDs co-ingested with alcohol and other drugs among a sample of people who regularly use illicit stimulant drugs. DESIGN AND METHODS In 2010, 693 Australians who regularly used ecstasy completed a 1-h interview about their past six-month ED and drug use. RESULTS Three-quarters of the sample (77%) had recently consumed EDs with other substances, primarily alcohol (70%) and ecstasy (57%). People who consumed ED with alcohol versus those who had consumed ED with ecstasy and with alcohol (only 8% reported only consuming ED with ecstasy) had similar profiles in regards to demographics, drug use, mental health and drug-related problems. Primary motives for consuming ED with alcohol included increased alertness (59%), the taste (25%), to party for longer (23%) and to combat fatigue (16%). One-half (52%) and one-quarter (27%) of participants who consumed EDs with alcohol and with ecstasy respectively had recently experienced adverse outcomes post-consumption, primarily headaches (24% and 11%) and heart palpitations (21% and 14%). DISCUSSION AND CONCLUSIONS Co-ingestion of EDs with licit and illicit drugs is common among people who regularly use ecstasy and related drugs. Adverse outcomes of co-ingestion suggest that targeted education regarding negative interactive drug effects is crucial for harm reduction.

Offenders as victims: post-traumatic stress disorder and substance use disorder among male prisoners

Background: Comorbid substance use disorder(s) and post-traumatic stress disorder (SUD-PTSD) is common among prisoners and linked to an increased risk of criminal recidivism; however, little is known about the characteristics of prisoners with this comorbidity. Aim: This study provides a preliminary examination of the clinical and criminal profile of male inmates with symptoms of SUD-PTSD, and examines whether this profile differs according to whether a person has experienced a trauma while in prison. Methods: Thirty male inmates from two correctional centres in Sydney, Australia, were recruited and assessed using a structured interview. Results: The sample reported extensive criminal, substance use and trauma histories. A history of substance dependence was almost universal (90%) and 56.7% met diagnostic criteria for PTSD with the remainder experiencing sub-threshold symptoms. Forty-three per cent reported a traumatic event while in prison. Those who had experienced trauma in prison, compared to those who had not, were more likely to nominate heroin as their main drug of concern and to be receiving drug treatment in prison. There was also a trend toward inmates who had experienced a trauma in prison being more likely than inmates who had no prison trauma to have experienced a physical assault. Conclusion: Male prisoners with SUD-PTSD are a high-needs group yet treatment responses are poor. Further research examining treatment options for this comorbidity may improve prisoner well-being and reduce recidivism.

Examining supply changes in Australia's cocaine market.

INTRODUCTION AND AIMS Media attention to cocaine use and supply has increased following some of the largest cocaine seizures in Australias history. Whether there has been an expansion in supply remains unclear. This paper examines the evidence behind assertions of increased supply in Australia and the scale and nature of any apparent increase, using proxy indicators of cocaine importation, distribution and use. DESIGN AND METHODS Eight proxies of cocaine importation, distribution and use were adopted, including amount of importation, mode of importation and supply flows to Australia. Each proxy indicator was sourced using publicly available and Australia-wide data, including information on the total weight of border seizures, mode of detection and country of embarkation of individual seizures. Data permitting, trends were examined for up to a 12 year period (1997-1998 to 2009-2010). RESULTS Since 2006-2007 there was evidence of increased cocaine importation, albeit less than between 1998-1999 and 2001-2002. There were further signs that the 2006-2007 expansion coincided with a diversification of trafficking routes to and through Australia (beyond the traditional site of entry-Sydney) and shifts in the geographic distribution of use. DISCUSSION AND CONCLUSIONS The congruity between indicators suggests that there has been a recent expansion in cocaine supply to and distribution within Australia, but that the more notable shift has concerned the nature of supply, with an apparent growth in importation and distribution beyond New South Wales. The diversification of cocaine supply routes may increase risks of market entrenchment and organised crime throughout Australia.

Tobacco and e-cigarette use amongst illicit drug users in Australia

OBJECTIVE To examine the rates and patterns of tobacco and e-cigarette use amongst two samples of illicit drug users in Australia. METHOD Data were obtained from the 2015 Illicit Drug Reporting System (IDRS) and the 2015 Ecstasy and Related Drugs Reporting System (EDRS). These studies comprised cross-sectional samples of 888 people who inject drugs (PWID) and 763 regular psychostimulant users (RPU). RESULTS Tobacco was consumed by the majority of both samples, however, use in the 6 months preceding interview was significantly higher amongst PWID (92.2%) than RPU (82.4% [OR 2.53 95% CI 1.86-3.44]). Inversely, PWID were less likely to have a history of e-cigarette use: 31.5% of PWID reported lifetime use of e-cigarettes (vs. 57.0% of RPU [OR 0.35 95% CI 0.28-0.42]) and 18.1% reported use in the 6 months preceding interview (vs. 33.7% of RPU [OR 0.44 95% CI 0.35-0.55]). PWID were more than three times as likely than RPU to report using e-cigarettes as a smoking cessation tool (OR 3.09 95% CI 2.03-4.71), but were less likely to use e-liquids that contained nicotine (OR 0.52 95% CI 0.32-0.83). Higher levels of poly drug use, daily tobacco use, recent use of synthetic cannabinoids and employment status were found to be significantly associated with e-cigarette use. CONCLUSION The use of e-cigarettes was relatively common amongst Australian samples of PWID and RPU. Whilst the majority of PWID reported using e-cigarettes as a smoking cessation tool, it appears that RPU are using them for experimental or recreational purposes.

Changes in Australian injecting drug users’ mental health problems and service uptake from 2006-2012

Purpose – The purpose of this paper is to assess changes in rates of mental health problems and service utilisation for Australian regular injecting drug users (IDUs) from 2006 to 2012. Design/methodology/approach – Data were taken from Illicit Drug Reporting System national surveys with 914 regular IDUs in 2006 and 883 in 2012. Changes in rates of self-reported mental health problems and service use were assessed. Findings – Rates of self-reported mental health problems increased from 38.3 per cent in 2006 to 43.7 per cent in 2012 – mainly due to increases in anxiety rates. Conversely, there was a decrease in mental health service use from 70.2 to 58.4 per cent by 2012. However, there was a proportional increase in the use of psychologists. These trends remained after controlling for socio-demographic and medical differences between the 2006/2012 samples. K10 scores for 2012 participants validated the use of the self-report measures. Practical implications – Reductions in stigma, improvements in mental h...

Corrigendum to “Characterising dark net marketplace purchasers in a sample of regular psychostimulant users” [International Journal of Drug Policy 35 (2016) 32–37]

The authors regret that there is an inconsistency between figures presented in the abstract and those reported in the text of the manuscript. Specifically, the abstract states that 68 out of 800 participants in the sample reported recent darknet use, while the manuscript states that 66 of the 745 participants reported recent darknet use. The latter numbers are correct for the analyses performed, that is, 66 of the 745 interviewed participants had purchased from the darknet in the preceding 12 months, and comprise the sample included in the regression model. While the former numbers are correct for the entire sample of recruited participants, they are not appropriate for the analyses performed. The authors would like to apologise for any inconvenience caused.
