Abstract
Crystal methamphetamine is used by gay men in Sydney in a variety of social and sexual contexts and by various means including injection. This paper presents detailed ethnographic data that explore some of the social and cultural characteristics of Sydney gay men's crystal use and other associated practices. The meaning of these practices is explored through a discussion of cultural boundaries and social exchange that traverses them. These boundaries help to limit drug-related harms in some ways but also generate certain risks. A nuanced understanding of the cultural meaning of various drug use practices may assist in producing culturally relevant harm-reduction education.

Abstract
This review analyzes contemporary literature in the context of Australian aging methamphetamine users, service response, and challenges to provision of care to this population. The article focuses on Australian literature with comparisons made with trends arising from international scholarship. Searches of the CINAHL, ProQuest, and Scopus electronic journal databases were performed in early 2014 as part of a wider study investigating dual diagnosis in older adults. Methamphetamine abuse is common in individuals with comorbid mental illness. The literature presented in this review outlines potential neuropsychological and persistent psychiatric sequelae associated with the use of methamphetamine, along with a number of concerning behaviors prevalent in individuals with comorbid human immunodeficiency virus-positive status. Despite an abundance of literature discussing methamphetamine use in adult populations, this is the first review exploring methamphetamine use in the context of aging and older adult mental health. Contemporary literature suggests that methamphetamine dependence will be a significant challenge for services that cater to older adults, requiring further research to fully assess the impact this cohort will have on the healthcare system.

Abstract
Substance use in young people (aged 10-24 years) might disrupt key periods of transition that occur as the adolescent brain undergoes cognitive and emotional development, and key psychosocial transitions are made. Adolescence is the peak time for initiation of substance use, with tobacco and alcohol usually preceding the use of illicit drugs. Substantial variation is noted between countries in the levels, types, and sequences of substance use in young people, indicating that a young person's use of substances depends on their social context, drug availability, and their personal characteristics. The Global Burden of Disease (GBD) 2013 study suggests that the burden attributable to substance use increases substantially in adolescence and young adulthood. In young men aged 20-24 years, alcohol and illicit substance use are responsible for 14% of total health burden. Alcohol causes most health burden in eastern Europe, and illicit drug burden is higher in the USA, Canada, Australia, New Zealand, and western Europe. Large gaps exist in epidemiological data about the extent of drug use worldwide and much of what we know about the natural history of substance use comes from cohort studies in high-income countries undertaken decades ago, which hinders effective global policy responses. In view of the global epidemiological transitions from diseases of poverty to non-communicable diseases, the burden of disease and health risks among adolescents and young adults is likely to change substantially, in ways that will no doubt see substance use playing an increasingly large part.

Abstract
INTRODUCTION AND AIMS Substance use and psychotic symptoms/disorders are associated. There has been little examination of this issue in young offenders, despite elevated substance use in this group. DESIGN AND METHODS Semistructured interviews were conducted by trained researchers with 514 young offenders. Psychotic symptoms were assessed using a previously validated screening measure, with scores ≥3 indicative of possible psychotic disorder. Associations between this indicator and patterns of offending, common symptoms of mental disorders and health risk behaviours, including substance use were examined. The extent to which substance use and psychotic symptoms remained associated after adjustment for possible confounding was evaluated. RESULTS Thirteen percent screened positive for psychosis. Participants who screened positive for psychosis were more likely than those who did not to have: unstable housing; been expelled from school; a family history of substance use/mental health problems, and depressive symptoms. Amphetamine, sedative and cannabis dependence were all strongly associated with screening positive for psychosis. Screening positive remained significantly associated with amphetamine and sedative dependence, and daily cannabis and sedative use, in multivariable regressions. DISCUSSION AND CONCLUSIONS One in eight young offenders reported symptoms consistent with psychosis. Symptomatology was strongly associated with heavy use of a range of illicit drugs. Given the frequency of these symptoms and the potential for them to be related to or exacerbated by drug use, this study highlights the importance of co-ordinated alcohol and other drugs and mental health treatment for young offenders, both due to co-occurrence and given the possibility that treating SUDs may impact on mental health symptoms.

Abstract
Psychotic symptoms and syndromes are frequently experienced among individuals who use methamphetamine, with recent estimates of up to approximately 40 % of users affected. Although transient in a large proportion of users, acute symptoms can include agitation, violence, and delusions, and may require management in an inpatient psychiatric or other crisis intervention setting. In a subset of individuals, psychosis can recur and persist and may be difficult to distinguish from a primary psychotic disorder such as schizophrenia. Differential diagnosis of primary vs. substance-induced psychotic disorders among methamphetamine users is challenging; nevertheless, with careful assessment of the temporal relationship of symptoms to methamphetamine use, aided by state-of-the art psychodiagnostic assessment instruments and use of objective indicators of recent substance use (i.e., urine toxicology assays), coupled with collateral clinical data gathered from the family or others close to the individual, diagnostic accuracy can be optimized and the individual can be appropriately matched to a plan of treatment. The pharmacological treatment of acute methamphetamine-induced psychosis may include the use of antipsychotic medications as well as benzodiazepines, although symptoms may resolve without pharmacological treatment if the user is able to achieve a period of abstinence from methamphetamine. Importantly, psychosocial treatment for methamphetamine dependence has a strong evidence base and is the optimal first-line treatment approach to reducing rates of psychosis among individuals who use methamphetamines. Prevention of methamphetamine relapse is the most direct means of preventing recurrence of psychotic symptoms and syndromes. Long-term management of individuals presenting with recurrent and persistent psychosis, even in the absence of methamphetamine use, may include both behavioral treatment to prevent resumption of methamphetamine use and pharmacological treatment targeting psychotic symptoms. In addition, treatment of co-occurring psychiatric disorders including depression and anxiety is important as a means of preventing relapse to methamphetamine use, which is often triggered by associated symptoms.

Abstract
Background Methamphetamine (METH) use, especially in females, has become a growing public health concern in China. In this study, we aimed to characterize the factors that contributed to drug craving in female METH users under isolated compulsory detoxification. We characterized factors contributing to craving such as duration of detoxification, history of drug use and self-reported mood state. Methods Subjects (N=113) undergoing a 1- to 3-year METH detoxification program were recruited from the Zhejiang Compulsory Detoxification Center for Women. The Questionnaire of METH-use Urge (QMU) was used to evaluate the level of craving for METH. The Abbreviate Profile of Mood States (A-POMS) was applied as an assessment for the negative mood disturbances. Results The participants were at a mean age of 25.2, primarily lowly educated and unemployed, and single. Smoking was the only route of METH administration at an average dose of 0.5 g/day, and 4 times/week. The reported craving level was positively correlated with the negative mood disturbances and the weekly dose of METH, but independent of the duration of detoxification. Furthermore, all five aspects of negative mood disturbances, including fatigue, bewilderment, anxiety, depression and hostility, were shown to positively correlate to the self-reported craving level after controlling for weekly dose of METH. Conclusions The data demonstrate a robust correlation between mood distress and craving for METH. Our results call for close evaluation of mood distress in treatment of METH users in China.

Abstract
Accumulating evidence suggests that genetic factors contribute to the vulnerability to methamphetamine (MAP) abuse and associated psychiatric symptoms. Chronic MAP abuse leads to psychosis, which may be of a transient or a prolonged type. Serotonergic dysfunction has been proposed as one of the contributory factors in the development of MAP psychosis. Our PET studies revealed that the serotonin transporter (5-HTT) density in global brain regions is significantly lower in MAP abusers. In this study, we examined the role of a functional polymorphism in the 5' flanking region of the 5-HTT gene (5-HTTLPR) in the development of MAP psychosis in a Japanese population. We analyzed DNA samples from 166 MAP patients (95 with transient and 71 with prolonged psychosis) and 197 age-, sex-, and geographic-origin-matched healthy controls. Patients were also subdivided according to the presence (n= 119) or absence (n= 148) of spontaneous relapse. We observed significant genotypic association of the 5-HTTLPR polymorphism with MAP psychosis (P= 0.022), particularly in patients who show prolonged psychosis. The frequency of the S allele in patients with prolonged psychosis was significantly higher than that of the controls (P= 0.045); it was further higher in patients with prolonged psychosis with spontaneous relapse (P= 0.004). 5-HTTLPR has been suggested to regulate the transcriptional activity of 5-HTT, with S alleles showing lesser transcriptional efficiency and also lower 5-HT(1A) receptor-binding potential. Prolonged MAP use, combined with the high frequency of 5-HTTLPR S-alleles, may lead to reduced 5-HTT levels and 5-HT(1A) receptor-binding potential in the brain, resulting in the dysfunction of the serotonergic system. Thus, we suggest a possible role for the 5-HTTLPR polymorphism in MAP psychosis.

Abstract
Background Illicit methamphetamine use continues to be a public health concern in the United States. The goal of the current study was to use a relatively inexpensive methodology to examine the prevalence and demographic correlates of nonmedical methamphetamine use in the United States. Methods The sample was obtained through an internet survey of noninstitutionalized adults (n = 4,297) aged 18 to 49 in the United States in 2005. Propensity weighting methods using information from the U.S. Census and the 2003 National Survey on Drug Use and Health (NSDUH) were used to estimate national-level prevalence rates. Results The overall prevalence of current nonmedical methamphetamine use was estimated to be 0.27%. Lifetime use was estimated to be 8.6%. Current use rates for men (0.32%) and women (0.23%) did not differ, although men had a higher 3-year prevalence rate (3.1%) than women (1.1%). Within the age subgroup with the highest overall methamphetamine use (18 to 25 year olds), non-students had substantially higher methamphetamine use (0.85% current; 2.4% past year) than students (0.23% current; 0.79% past year). Methamphetamine use was not constrained to those with publicly funded health care insurance. Conclusion Through the use of an internet panel weighted to reflect U.S. population norms, the estimated lifetime prevalence of methamphetamine use among 18 to 49 year olds was 8.6%. These findings give rates of use comparable to those reported in the 2005 NSDUH. Internet surveys are a relatively inexpensive way to provide complimentary data to telephone or in-person interviews.

Abstract
OBJECTIVE A case of drug-induced psychosis related to crystalline methamphetamine is described, highlighting the phenomenology and relevant treatment. RESULTS A 44-year-old woman with borderline personality traits and severe drug dependence developed a protracted drug-induced psychosis related to chronic high-dose crystalline methamphetamine use. Complete resolution of symptoms occurred with antipsychotic medication and abstinence from methamphetamine. Rapid recurrence of symptoms occurred at a time of high stress associated with minimal methamphetamine use and cessation of low-dose quetiapine. Symptoms rapidly resolved with abstinence, quetiapine and reduction of stressors. CONCLUSIONS A drug-induced psychosis resembling paranoid schizophrenia can occur with repeated or high-dose use of methamphetamine. While this generally resolves rapidly with cessation of stimulant use, some cases of protracted drug-induced psychosis in vulnerable individuals have been documented. Behavioural sensitization can also occur, and neuroleptics may prevent the recurrence of further psychosis triggered by ongoing low-dose methamphetamine use.

Abstract
A series of N-aromatic, N-heteroaromatic, and oxygenated N-phenylpropyl derivatives of 1-(2-benzhydryloxyethyl)-piperazine and 1-[2-[bis-(4-fluorophenyl)methoxy]ethyl]piperazine, analogues of GBR 12909 (1a) and 12935 (1b), was synthesized and examined for their dopamine (DAT) and serotonin (SERT) transporter binding properties. One of these compounds, racemic 3-[4-(2-benzhydryloxyethyl)piperazin-1-yl]-1-(3-fluorophenyl)-propan-1-ol (33), had DAT affinity as good as, or better than, GBR 12909 and 12935, and was more selective for DAT over SERT than the GBR compounds. Both trans- (43) and cis- (47) (+/-)-2-(4-[2-[bis-(4-fluorophenyl)-methoxy]ethyl]piperazin-1-ylmethyl)-6-methoxy-1,2,3,4-tetrahydronaphthalen-1-ol had relatively good SERT selectivity and, as well, showed high affinity for SERT.

Abstract
A striking finding of the Illicit Drug Reporting System (IDRS) in recent years has concerned the emergence in Sydney of a number of different forms of potent methamphetamine. This paper demonstrates the operation of the IDRS in detecting and documenting an increase in both the availability and use of these forms of methamphetamine in Sydney, and Australia more widely, since 1998. Data from different components of the IDRS are utilized to propose that there are currently at least three forms of methamphetamine available in Sydney that are considered by the market to be distinct commodities: methamphetamine powder ('speed'), base methamphetamine ('base') and crystalline methamphetamine ('ice'/'shabu'/'crystal meth'). Base and ice are more potent forms of methamphetamine than speed, and international experience, along with preliminary data obtained from the IDRS, suggest that their use is associated with harms in a number of domains.
