Chronic pain and mental health issues like depression and anxiety significantly contribute to disease burden in Western countries. While cannabinoids are suggested to have analgesic, anxiolytic and antidepressant properties, evidence, especially for long-term use, is inconclusive. This 12-month observational study evaluated the effects of prescribed medicinal cannabis for 96 patients suffering from pain, as well as sleep disturbances, depression and anxiety.

Introduction: Western Australia has one of the highest rates of Aboriginal children entering out-of-home care in Australia. Kinship care is the preferred culturally safe out-of-home care option for Aboriginal children, yet all jurisdictions, including Western Australia, are far from meeting best-practice national standards. Intersectoral collaboration is a key primary healthcare principle and internationally recognized for improving health systems and outcomes.

Adolescent boys (age 9-19) are impacted differently by humanitarian emergencies. However, academic research on adolescent health and child protection has tended to focus on the direct impacts of an emergency rather than indirect impacts that may arise after a crisis. We sought to identify child protection concerns affecting adolescent boys in emergency settings and boys who are more vulnerable to harm through a case study of the humanitarian response to the 2017 Rohingya refugee crisis.

Article Synopsis
  • The study explored the ethical perspectives of alcohol and other drug (AOD) clinicians, highlighting that there has been insufficient focus on how ethics play a role in their clinical practice.
  • Participants, consisting of 30 AOD clinicians in Victoria, Australia, shared insights through various qualitative methods, revealing four key ethical goals that guide their work.
  • The findings suggest that while clinicians may not explicitly use ethical language, their goals—such as helping clients, challenging stigma, and ensuring safety—are fundamentally ethical, indicating a need to enhance the understanding and integration of ethics in AOD clinical settings.

Naturalistic and placebo-controlled studies suggest ayahuasca, a potent psychedelic beverage originating from Indigenous Amazonian tradition, may improve mental health, alter personality structure, and reduce alcohol and drug intake. To better understand ayahuasca's therapeutic potential and to identify factors that influence therapeutic efficacy, we conducted a naturalistic, longitudinal study of facilitated ayahuasca consumption in naïve participants using a comprehensive battery of self-report questionnaires. Ayahuasca naive individuals registering for ayahuasca ceremonies were asked to complete a range of validated questionnaires assessing mental health, alcohol/cannabis use, relationships, personality, and connection to self and spirituality, prior to and 1 month after attending an ayahuasca ceremony.

Background: Although long-term alcohol and tobacco use have widely been recognised as important risk factors for cancer, the impacts of alcohol and tobacco health policies on cancer mortality have not been examined in previous studies. This study aims to estimate the association of key alcohol and tobacco policy or events in Australia with changes in overall and five specific types of cancer mortality between the 1950s and 2013.

Methods: Annual population-based time-series data between 1911 and 2013 on per capita alcohol and tobacco consumption and head and neck (lip, oral cavity, pharynx, larynx and oesophagus), lung, breast, colorectum and anus, liver and total cancer mortality data from the 1950s to 2013 were collected from the Australian Bureau of Statistics and Cancer Council Victoria, the WHO Cancer Mortality Database and the Australian Institute of Health and Welfare.

While universal health coverage (UHC) has been praised as a powerful means to reduce inequalities and improve access to health globally, little has been said about how patients experience and understand its implementation locally. In this article, we explore the experiences of young Chileans with type 1 diabetes when seeking care in Santiago, within Chile's UHC program, which sought to improve people's access to health care. We argue that the implementation of UHC, within a structurally fragmented health system, did not lead to the promised equitable health care delivery.

Background: Although previous quantitative studies have documented the association between exposure to alcohol portrayals and drinking attitudes in Western countries, few qualitative studies have explored this matter in Thailand. A better understanding of the association in young Thais is required for a more efficient alcohol policy development. This study aims to explore the information young Thais have learnt from exposure to alcohol portrayals in society and the media, examine how this exposure shapes their drinking attitudes, and investigate the alignment of policy-makers' views on drinking with those of young people.

Introduction And Aims: The dominant Thai alcohol companies have strategically employed brand advertising and brand sharing (using a very similar branding for both alcoholic and non-alcoholic products) to circumvent restrictive alcohol advertising regulations. As empirical evidence confirms that exposure to alcohol advertisements increases youth drinking, young Thais could be at risk of constant and incidental exposure to alcohol advertising, hence leading to increased alcohol consumption. This study aims to explore young people's perceptions of these alcohol branding strategies and to examine how exposure to such advertising strategies affect their attitudes towards alcohol use.

Importance: Understanding whether the population-level consumption of alcohol and tobacco is associated with cancer mortality is a crucial question for public health policy that has not been answered by previous studies.

Objective: To examine temporal associations of alcohol and tobacco consumption with overall cancer mortality in the Australian population, looking across different sex and age groups.

Design, Setting, And Participants: This population-based cohort study conducted a time series analysis (autoregressive integrated moving average models) using aggregate-level annual time series data from multiple sources.

Introduction And Aims: The recognition of the association between the use of alcohol and negative health outcomes have led to the endorsement of the World Health Organization's global strategy to reduce the harmful use of alcohol. Given the capacities, capabilities and sociocultural contexts of Thailand, this study aims to examine the Thai alcohol policy against the global strategy's recommended policy measures for marketing control and identify areas for further policy development.

Design And Methods: Semi-structured interviews were conducted with the stakeholders from three sectors: the government, academia and civil society.

Aims: This study aims to measure the prevalence rates and patterns of help-seeking behavior as a consequence of being harmed by drinkers in five Asian countries (India, Sri Lanka, Vietnam, Lao PDR and Thailand).

Methods: A total of 9832 respondents aged 18-65 years from the WHO/ThaiHealth Collaborative Project were surveyed between 2012 and 2014 about their experiences of being negatively affected due to another's drinking, and whether and where they sought help, focusing on four adverse aspects of harms from others' drinking.

Results: The prevalence of seeking help from any source in the past year due to harm from others' drinking ranged from 7% to 20%.

The small, decentralised communities, known as outstations which satellite larger Indigenous Australian remote communities have often been conceptualised as places that are beneficial to health and well-being. This paper provides an exploration of the meaning of an outstation for one family and the benefits that this connection brings to them, which are expressed in a deep connection to the land, continuing relationships with ancestors and a safe refuge from the stresses of the larger community. We argue that the outstation provides a place for people to be in control of their lives and form hopes and plans for the future.

Background: Harm from alcohol-attributable aggression and violence is linked to diminished personal safety and reduced physical and mental health and wellbeing in many countries. But there has been limited evidence on these harms in low- and middle-income countries (LMICs). This study measured harm from others' drinking-related aggression, violence and misconduct in five Asian LMICs (Thailand, Sri Lanka, India, Vietnam, and Lao PDR), aiming to compare the magnitude and pattern of harm across countries by gender, age group, educational level, rurality, and country-level indicators.

Background: We report here selected findings from a mixed-methods study investigating the role of Australian rare disease patient organisations (RDPOs) in research. Despite there being many examples of RDPOs that have initiated and supported significant scientific advances, there is little information - and none at all in Australia - about RDPOs generally, and their research-related goals, activities, and experiences. This information is a pre-requisite for understanding what RDPOs bring to research and how their involvement could be strengthened.

This paper examines young people's perceived vulnerability to sexually transmitted infections (STIs) and their efforts to create a sense of personal safety within an environment in which risks may be high and where STIs are highly stigmatised. The paper reports on findings from research involving both Indigenous and non-Indigenous 16- to 25-year-olds from remote, rural and regional Australia, including communities in the Northern Territory, Western Australia and South Australia. The study used qualitative methods, including body mapping and scenario based interviewing, to explore how young people made decisions about potential sexual partners and how STIs were understood within the context of young people's everyday social worlds.
