The utility of the Mood Disorders Questionnaire as a screening tool in a methadone maintenance treatment program

Objective. Comorbid mental illness amongst methadone maintenance therapy clients may be common and screening may be warranted. The Mood Disorders Questionnaire (MDQ) is a screening tool for bipolar disorder that has been validated in other treatment settings. Its utility for patients with substance use disorders is assessed in this study.

Methods. Clients of a methadone maintenance program were invited to complete the MDQ when they attended a public Drug and Alcohol Service for their regular scheduled appointments. Information about their history of substance use was also collected.

Results. Eighty clients (43 females, 37 males) aged 35 8.0 years (mean SD) participated in the study. Seventy-four clients completed the MDQ of which 36 (48.6%) obtained a positive screen. A check of client fi les suggested that only three of the 74 participants had a current working diagnosis of bipolar disorder. These three participants had screened positive on the MDQ.

Conclusions. There was a high prevalence of manic symptoms reported by participants, suggesting that screening for bipolar disorder in this population may be warranted. However, there is a risk of false positives with the MDQ, as it does not clearly differentiate between symptoms of mania and drug intoxication.

Sustained low-efficiency dialysis with filtration (SLEDD-f) in the management of acute sodium valproate intoxication

Hemodialysis is only infrequently used in drug overdosage situations. The efficacy of hemodialysis to remove the drug depends upon the pharmacokinetics and pharmacodynamics of the drug. At normal therapeutic concentrations, valproic acid is predominantly protein bound and therefore removal by hemodialysis is limited. In an overdose situation, protein binding is rapidly saturated and therefore the substantially larger quantities of the free drug can rapidly cause toxicity. Slow low-efficient daily diafiltration (SLEDD) has not previously been utilized in a drug overdose situation. We report the effective use of SLEDD to remove high toxic concentrations of valproic acid in an overdose situation. Slow low-efficient daily diafiltration also prevented the rebound phenomenon that can occur as the excess drug is released from its protein-bound stores. Hybrid dialysis therapies deserve further evaluation in the management of other poisonings where extra-corporeal therapy is indicated.

It blasted me into space : intoxication and an ethics of pleasure

O'Malley and Valverde point out that in the 21st century, pleasure is a warrantable motive for drug and alcohol use only when it is attached to the idea of moderation. This presents a problem for those researchers who wish to theorise about those individuals who use drugs deliberately to induce intoxication. This paper uses unconventional means to come to an understanding of intoxication, it uses the stories of interviewed former heroin addicts, published autobiographies, biographies and even some fictional accounts to come to an understanding of the. difficulties of dealing with intoxication and the drug-using subject, it also uses the accounts that Michel Foucault gave about his own use of drugs and its relationship to an ethics of pleasure and resistance. The article uses theories of risk and edgework to understand the underlying meanings of intoxication to many drug users.

Patron offending and intoxication in night time entertainment districts (POINTED) : a study protocol

Risky alcohol consumption is the subject of considerable community concern in Australia and internationally, particularly the risky drinking practices of young people consuming alcohol in the night-time economy. This study will determine some of the factors and correlates associated with alcohol-related risk-taking, offending and harm in and around licensed venues and night-time entertainment precincts across five Australian cities (three metropolitan and two regional). The primary aim of the study is to measure levels of pre-drinking, drinking in venues, intoxication, illicit drug use and potentially harmful drinking practices (such as mixing with energy drinks) of patrons in entertainment areas, and relating this to offending, risky behaviour and harms experienced. The study will also investigate the effects of license type, trading hours, duration of drinking episodes and geographical location on intoxication, offending, risk-taking and experience of harm. Data collection involves patron interviews (incorporating breathalysing and drug testing) with 7500 people attending licensed venues. Intensive venue observations (n=112) will also be undertaken in a range of venues, including pubs, bars and nightclubs. The information gathered through this study will inform prevention and enforcement approaches of policy makers, police and venue staff.

'Wide-awake drunkenness'? Investigating the association between alcohol intoxication and stimulant use in the night-time economy

Aims: We tested whether patrons of the night-time economy who had co-consumed energy drinks or illicit stimulants with alcohol had higher blood alcohol concentration (BAC) levels than patrons who had consumed only alcohol. Design: Street intercept surveys (n=4227) were undertaken between 9 p.m. and 5 a.m. over a period of 7 months. Setting: Interviews were undertaken with patrons walking through entertainment precincts, queuing to enter venues or exiting venues in five Australian cities. Participants: The response rate was 92.1%; more than half the study sample was male (60.2%) and the median age was 23 years (range 18-72). Measurements: Data were collected on demographics, length of drinking session, venue types visited, types and quantity of alcohol consumed and other substance use. A BAC reading was recorded and a subsample of participants was tested for other drug use. Findings: Compared with the total sample (0.068%), illicit stimulant consumers (0.080%; P=0.004) and energy drink consumers (0.074%; P<0.001) had a significantly higher median BAC reading, and were more likely to engage in pre-drinking (65.6, 82.1 and 77.6%, respectively, P<0.001) and longer drinking sessions (4, 5 and 4.5 hours, respectively, P<0.001). However, stimulant use was not associated independently with higher BAC in the final multivariable model (illicit stimulants P=0.198; energy drinks P=0.112). Interaction analyses showed that stimulant users had a higher BAC in the initial stages of the drinking session, but not after 4-6 hours. Conclusions: While stimulant use does not predict BAC in and of itself, stimulants users are more likely to engage in prolonged sessions of heavy alcohol consumption and a range of risk-taking behaviours on a night out, which may explain higher levels of BAC among stimulants users, at least in the initial stages of the drinking session.

Correlates and motives of pre-drinking with intoxication and harm around licensed venues in two cities

INTRODUCTION AND AIMS: The study investigates the prevalence of pre-drinking culture in the night-time economy (NTE) and its impact upon intoxication and alcohol-related harm and violence experienced by patrons. DESIGN AND METHODS: Cross-sectional surveys were conducted in and around licensed venues in Newcastle (NSW) and Geelong (Victoria) during peak trading hours (typically 9pm-1am). Participants completed a five minute structured interview which targeted: demographics, past and planned movements on the survey night, safety/experience of harm, and patron intoxication. 3949 people agreed to be interviewed, a response rate of 90.7%. Around half (54.9%) of interviewees were male and mean age was 24.4 years (SD = 5.8). RESULTS: 66.8% of participants reported pre-drinking prior to attending licensed venues. On a 1-10 scale measuring self-rated intoxication, pre-drinkers scored significantly higher compared to non pre-drinkers (P < 0.001). Compared to non-pre-drinkers, patrons who had consumed 6-10 standard pre-drinks were 1.5 times more likely to be involved in a violent incident in the past 12 months (OR = 1.50, 95%CI 1.03-2.19, P = 0.037) increasing to 1.8 times more likely for patrons who had 11-15 drinks (OR = 1.80, 95%CI 1.04-3.11 P = .036). Pre-drinking was also associated with both self-rated and observer-rated intoxication, as well as increased probability of illicit drug use. Amongst pre-drinkers, price was the most commonly reported motive for pre-drinking (51.8%). DISCUSSION AND CONCLUSIONS: 'Pre-drinking' was normal behaviour in the current sample and contributes significantly to the burden of harm and intoxication in the NTE. Price disparity between packaged vs. venue liquor is a key motivator for pre-drinking.

Drug use in Australian nightlife settings: estimation of prevalence and validity of self-report

AIMS: This study aimed to 1) estimate the prevalence of illicit drug use in night-time entertainment districts across five major cities in Australia; and 2) validate self-reported drug use using biochemical marker oral swabs. DESIGN: Street intercept surveys and oral drug swabs conducted over a seven-month period during 2011-2012. SETTING: The night-time entertainment districts of three metropolitan cities (Sydney, Melbourne and Perth) and two regional cities (Wollongong and Geelong) in Australia, between the hours of 10 pm and 5 am. PARTICIPANTS: 7,340 individuals agreed to participate in the survey (a 93% response rate). More than half (62%) of the sample was male, with a median age of 22 years (range 18-73). MEASUREMENTS: Patrons were approached in thoroughfares, and while entering and leaving licensed venues. Data collected included demographics and current session alcohol and other substance use. Drug swabs (n = 401) were performed with a sub-sample of participants. FINDINGS: Approximately 9% (95% CI, 7% to 12%) of participants self-reported consumption of illicit or non-prescribed pharmaceutical drugs prior to interview; of those, 81% identified psychostimulants as the drug used. One in five drug swabs returned a positive result, with psychostimulants the most commonly detected drugs (15%; 95% CI, 12%-19%). Kappa statistics indicate agreement between self-report of any illicit drug and a positive drug swab is in the slight range (κ = 0.12 (95% CI, .05 to .20) p = .000). CONCLUSIONS: Self-report findings suggest drug use in the nightlife in Australia is common, though still very much a minority past-time. Drug swabs indicate a higher prevalence of use (20%) than self-report (9%), which suggests that self-reported drug use may not be reliable in this context. This article is protected by copyright.

Sober assessment of the link between substance abuse and crime-eliminating drug and alcohol use from the sentencing calculus

The relevance of drug and alcohol involvement to sentencing law and practice is one of the most perplexing and unsettled areas of sentencing law and practice.1 It is also one of the most important issues in the criminal justice system. Most crimes are committed by offenders who are substance involved, and nearly half of all crimes that are committed are done so by offenders who are intoxicated at the time of the offense. Substance involved individuals are grossly over-represented in the criminal courts. Addiction and intoxication impair sound judgment, and hence, it intuitively appears that intoxicated offenders are less culpable for their crimes. Moreover, there is often a sense that addiction and intoxication causes aberrant behavior and that curing the substance involvement will lead to more prudent (law-abiding) conduct.
