This paper summarizes the development and evaluation of an assessment instrument for children ages 7-12. The CHILD CARRE measure is a semi-structured interview with 7 domains. Children from the USA and Argentina (N = 134) completed baseline and follow-up assessments. Substance use occurred at an average age of 8. Almost 33% of the children were taking medications for medical issues, more than 50% of them said that medical problem gets in the way of doing things they like to to do and almost 64% of the children stated that they would like to feel better. On average, children completed third grade in school, 56% of them knew how to read and 26% of the children started making money at age 8. Most children (74%) saw someone drunk or high and 23% of children reported alcohol or psychoactive substance use. Among these children using substances, such substance use occurred at an average age of 8, and in the past 30 days they used these substances an average for 5 days. The rating of level of risk on the part of the interviewer placed these children in the "risky" to "very risky" categories. Most children reported seeing their family members smoking (83%) or using alcohol (67%), and 49% reported seeing their family members high on drugs. Few children (10%) had conflicts with the law, while 46% of their family members had legal problems. Some children (30%) reported having serious problems getting along with family members, neighbors, or friends. These results suggest that this measure can serve as the first comprehensive measure to assess multiple life domains for young children at risk for or using psychoactive substances.

Levamisole is a veterinary anthelmintic drug and a common adulterant of misused drugs. This study analyses the lethal, antinociceptive and haematological effects produced by acute or repeated levamisole administration by itself or combined with morphine. Independent groups of male Swiss Webster mice were i.p. injected with 100 mg/kg morphine, 31.6 mg/kg levamisole (lethal doses at 10%, LD10 ) or the same doses combined. Naloxone pretreatment (10 mg/kg, i.p.) prevented morphine-induced death, as did 2.5 mg/kg, i.p. mecamylamine with levamisole. Co-administration of levamisole and morphine (Lvm + Mor) increased lethality from 10% to 80%. This augmented effect was prevented by 30 mg/kg, i.p. naloxone and reduced with 10 mg/kg naloxone plus 2.5 mg/kg, i.p. mecamylamine. In independent groups of mice, 17.7 mg/kg, i.p. levamisole antagonized the acute morphine's antinociceptive effect evaluated in the tail-flick test. Repeated 17.7 mg/kg levamisole administration (2×/day/3 weeks) did not affect tolerance development to morphine (10 mg/kg, 3×/day/1 week). Blood samples obtained from mice repeatedly treated with levamisole showed leukopenia and neutropenia. Morphine also produced neutropenia, increased erythrocyte count and other related parameters (e.g. haemoglobin). Lvm + Mor had similar effects on leukocyte and neutrophil counts to those seen with levamisole only, but no erythrocyte-related alterations were evident. Blood chemistry analysis did not indicate liver damage but suggested some degree of electrolyte balance impairment. In conclusion, Lvm + Mor increased death risk, altered morphine-induced antinociceptive effects and produced haematologic abnormalities. The importance of studying combinations of drugs of abuse lies in the fact that drug users frequently combine drugs, which are commonly adulterated. [ABSTRACT FROM AUTHOR]

Toxic adulterants are drug or chemical agents used to add bulk volume to traditional drugs of abuse such as cocaine and heroin. These cutting agents include levamisole, metamizole, noxiptillin, phenacetin and xylazine as well as common legal drugs such as acetaminophen, caffeine, diphenhydramine, lidocaine, quinine, quetiapine and tramadol. Because they possess pharmacological activity they result in exposure of the user, but also in the case of pregnant women, the developing fetus, to potential drug toxicity. We describe the development, validation and implementation of a rapid (48 second sample-to-sample) test based on a qualitative data-dependent liquid chromatography–quadrupole time of flight mass spectrometry method for the analysis of toxic adulterating substances in umbilical cord tissue (UCT) samples. The method provides a means of studying potential in utero exposure to these agents. Library spectra comparison at three different collision energies was used in conjunction with retention time and accurate mass to identify these substances in UCT. Analytically based reporting limits were established to determine positivity rates of adulterants in UCT utilizing a standard addition approach. The method was applied to authentic cocaine and opioid positive UCT to screen for toxic adulterants. There were a total of 82 potential adulterant positives found in a 30-sample cohort of authentic UCT samples, with an average of 2.7 substances per case. Lidocaine was the predominant finding followed by caffeine, and diphenhydramine all of which could result from non-illicit drug exposure, however, there were positives for levamisole, phenacetin, noxiptillin and xylazine none of which are approved in the United States for human therapeutic use. This initial set of data established a preliminary positivity rate of potentially toxic adulterants in UCT samples positive for cocaine or opioid use. [ABSTRACT FROM AUTHOR]

Abstract Background The purpose of this study was to assess the impact of drug abuse treatment in Peru that used the therapeutic community (TC) model. Program directors and several staff members from all study treatment facilities received two to eight weeks of in-country training on how to implement the TC treatment model prior to the follow-up study. Methods This outcome study involved 33 TC treatment facilities and 509 former clients in Lima and other cities in five providences across Peru. A retrospective pre-test (RPT) follow-up design was employed in which 30-day use of illegal drugs and alcohol to intoxication was measured at baseline retrospectively, at the same time of the six-month follow-up. In-person interview data were collected from directors of 73 percent of the eligible TC organizations in January and February 2003 and from former 58 percent of the eligible TC former clients between October 2003 and October 2004. Drug testing was conducted on a small sample of former clients to increase the accuracy of the self-reported drug use data. Results Medium to large positive treatment effects were found when comparing 30-day illegal drug and alcohol use to intoxication before and six months after receiving treatment. As a supplemental analysis, we assumed the 42 percent of the former clients who were not interviewed at the six month assessment had returned to drugs. These results showed medium treatment effects as well. Hierarchical Generalized Linear Modeling (HGLM) results showed higher implementation fidelity, less stigma after leaving treatment, and older clients, singly or in combination are key predictors of treatment success. Conclusion This study found that former clients of drug and alcohol treatment in facilities using the TC model reported substantial positive change in use of illegal drugs and alcohol to intoxication at a six-month follow-up. The unique contribution of this study is that the results also suggest attention should be placed on the importance of implementing the TC drug abuse treatment model with fidelity. Further, the results strongly suggest that TC drug abuse treatment programs should incorporate follow-up activities that attempt to neutralize community negative reactions (perceived stigma) independent of other factors.

The following report summarizes a study performed on seized drug exhibits collected in two U.S. states to evaluate the presence and identification of cutting agents. Aliquots of seized drug materials from Kentucky (n = 200) and Vermont (n = 315) were prepared using a dilute‐and‐shoot procedure. Initial analysis was performed using gas chromatography–mass spectrometry (GC‐MS) followed by analysis using liquid chromatography quadrupole time‐of‐flight mass spectrometry (LC‐QTOF). Active compounds detected overall included caffeine (31.0%), quinine/quinidine (24.7%), levamisole (11.6%), acetaminophen, (8.2%) and procaine (8.2%). These compounds were found with several drugs of abuse, such as heroin, fentanyl, methamphetamine, and cocaine. This novel information about cutting agents used to dilute or alter drugs of abuse is important to criminal investigations and in the management of acute intoxications at health centers. However, common methodologies for analysis and standard reporting practices frequently do not include cutting agents, resulting in lacking or inadequate information regarding prevalence of these substances.

Objective.The current study examines gender differences in drug-abuse treatment (DAT) entry, dropout, and outcomes in seven DAT centers in Afghanistan. This is the first study to examine gender differences in DAT programming in Afghanistan. Design.A prospective cohort design of 504 women and men in seven DAT centers in Afghanistan was used in this study and the analyses examined whether gender differences exist for patients (1) at treatment entry, (2) at treatment dropout, and (3) for treatment outcomes. Results.Gender differences were found at baseline for patient characteristics, drug use, crime, and social and occupational functioning. Results showed a trend that women remained in treatment longer than men. Looking at gender differences in treatment success, results showed greater reductions in drug use and crime, and greater social functioning among women. Conclusion.Results provide preliminary evidence for potential treatment success of women-tailored DAT programming in Afghanistan. Results also indicate that DAT appears to be successful among Afghan men; however, lower positive outcomes for men when compared to women suggest that more efforts should focus on tailoring DAT programming to the specific needs of Afghan men as well. Study limitations are addressed, and important policy implications are discussed. [ABSTRACT FROM AUTHOR]

Denial of human rights, gender disparities, and living in a war zone can be associated with severe depression and poor social functioning, especially for female drug abusers. This study of Afghan women in drug abuse treatment (DAT) centers assesses (a) the extent to which these women have experienced human rights violations and mental health problems prior to entering the DAT centers, and (b) whether there are specific risk factors for human rights violations among this population. A total of 176 in-person interviews were conducted with female patients admitted to three drug abuse treatment centers in Afghanistan in 2010. Nearly all women (91%) reported limitations with social functioning. Further, 41% of the women indicated they had suicide ideation and 27% of the women had attempted suicide at least once 30 days prior to entering the DAT centers due to feelings of sadness or hopelessness. Half of the women (50%) experienced at least one human rights violation in the past year prior to entering the DAT centers. Risk factors for human rights violations among this population include marital status, ethnicity, literacy, employment status, entering treatment based on one's own desire, limited social functioning, and suicide attempts. Conclusions stemming from the results are discussed. [ABSTRACT FROM AUTHOR]

Background: A worldwide and ever-growing population of children are using psychoactive substances. To slow this problem, the Child Intervention for Living Drug-Free (CHILD) Curriculum was created to train treatment providers on how to screen, assess, and treat children between the ages of 4-12 years of age exposed to or actively using psychoactive substances. The purpose of the present project was to evaluate the extent to which completion of a six-session training of the six courses of the CHILD Curriculum met the objective of increasing the participants' knowledge of the Curriculum's approach to treating children for substance use problems., Methods: 71 participants from Africa, Asia, and South America were invited for training and 100% accepted the invitation. Trainees completed an in-person small-group course, occurring over 32 days and comprising 256 total hours. During the CHILD Curriculum training, they completed six separate, 20-item, multiple choice knowledge assessment measures, one for each of the six courses comprising the Curriculum., Results: Significant (ps<.001) improvement in knowledge in each course was associated with a multivariate measure of strength of the relationship that indicated the change was substantial for five courses (R 2 s>.5) and moderate for a sixth course. Percentage change from baseline varied from a low of 17% to a high of 63%., Conclusion: The CHILD Curriculum provides a useful educational framework to ensure knowledge gains by trainees. This curriculum content and evaluation provides a framework for future training of providers to pre-adolescent children who use psychoactive substances or are at risk for such use.

Psychoactive substance use among children in Afghanistan is an issue of concern. Somewhere around 300,000 children in the country have been exposed to opioids that either parents directly provided to them or by passive exposure. Evidence-based and culturally appropriate drug prevention and treatment programs are needed for children and families. The goals of this study were to: (1) examine lifetime psychoactive substance use in girls and boys at treatment entry; and (2) examine differential changes in substance use during and following treatment between girls and boys. Children ages 10-17 years old entering residential treatment were administered the Alcohol, Smoking and Substance Involvement Screening Test for Youth (ASSIST-Y) at pre- and post-treatment, and at three-month follow-up. Residential treatment was 45 days for children and 180 days for adolescents and consisted of a comprehensive psychosocial intervention that included education, life skills, individual and group counseling and, for older adolescents, vocational skills such as embroidery and tailoring. Girls and boys were significantly different regarding lifetime use of five substances at treatment entry, with girls less likely than boys to have used tobacco, cannabis, stimulants, and alcohol, and girls more likely than boys to have used sedatives. Differences between boys and girls were found for past-three-month use of four substances at treatment entry, with girls entering treatment with higher past-three-month use of opioids and sedatives, and boys with higher past-three-month use of tobacco, cannabis, and alcohol. Change over the course of treatment showed a general decline for both girls and boys in the use of these substances. Girls and boys in Afghanistan come to treatment with different substance use histories and differences in past-three-month use. Treatment of children for substance use problems must be sensitive to possible differences between girls and boys in substance use history., Competing Interests: Competing interests.
