Alcohol use and alcohol use disorders in sub-Saharan Africa: A systematic review and meta-analysis.

BACKGROUND AND AIMS: Population-level alcohol use data are available from high-income countries, but limited research has been conducted in sub-Saharan Africa. This systematic review and meta-analysis aimed to summarize population-level alcohol use in sub-Saharan Africa. METHOD: Databases searched included PubMed, EMBASE, PsycINFO and AJOL, without language restrictions. Searches were also conducted in the Global Health Data Exchange (GHDx) and Google Scholar. Search terms encompassed 'substance' or 'substance-related disorders' and 'prevalence' and 'sub-Saharan Africa'. We included general population studies on alcohol use (including any use, high-risk alcohol use and alcohol use disorders) from 2018 onwards. Prevalence data for alcohol use among sub-Saharan African adolescents (10-17) and adults (18+) were extracted. Analyses included life-time and past 12- and 6-month alcohol use. RESULTS: We included 141 papers. Among adolescents, the life-time prevalence of alcohol use was 23.3% [95% confidence interval (CI) = 11.3-37.1%], 36.2% (CI = 18.4-56.1%) in the past year and 11.3% (CI = 4.5-20.4%) in the past 6 months. Among adolescents, 12-month prevalence of alcohol use disorder and alcohol dependence were 7.7% (CI = 0.0-27.8%) and 4.1% (CI = 1.4-7.9%), respectively. Among adults, the life-time prevalence of alcohol use was 34.9% (CI = 17.7-54.1%), 27.1% (CI = 5.0-56.4%) in the past year and 32.2% (CI = 19.8-46.0%) in the past 6 months. Among adults, the 12-month prevalence of alcohol use disorder and alcohol dependence were 9.5% (CI = 0.0-30.4%) and 4.3% (CI = 0.8-9.8%), respectively. The highest weighted life-time prevalence of alcohol use, 86.4%, was reported in Tanzania among adults. The highest weighted past 6-month prevalence of alcohol use, 80.6%, was found in Zambia among adolescents. CONCLUSION: Alcohol use patterns vary across countries and subregions within sub-Saharan Africa, and comprehensive population-level data on alcohol use remain scarce in numerous sub-Saharan African countries. The prevalence of alcohol use disorder is common among adolescents in sub-Saharan Africa.

The prevalence of cannabis use disorders in people who use medicinal cannabis: A systematic review and meta-analysis.

BACKGROUND: The prevalence of cannabis use disorders (CUDs) in people who use cannabis recreationally has been estimated at 22%, yet there is a dearth of literature exploring CUDs among people who use medicinal cannabis. We aimed to systematically review the prevalence of CUDs in people who use medicinal cannabis. METHODS: In our systematic review and meta-analysis, we followed PRISMA guidelines and searched three databases (PsychInfo, Embase and PubMed) to identify studies examining the prevalence of CUDs in people who use medicinal cannabis. Meta-analyses were calculated on the prevalence of CUDs. Prevalence estimates were pooled across different prevalence periods using the DSM-IV and DSM-5. RESULTS: We conducted a systematic review of 14 eligible publications, assessing the prevalence of CUDs, providing data for 3681 participants from five different countries. The systematic review demonstrated that demographic factors, mental health disorders and the management of chronic pain with medicinal cannabis were associated with an elevated risk of CUDs. Meta-analyses were conducted on the prevalence of CUDs. For individuals using medicinal cannabis in the past 6-12 months, the prevalence of CUDs was 29% (95% CI: 21-38%) as per DSM-5 criteria. Similar prevalence was observed using DSM-IV (24%, CI: 14-38%) for the same period. When including all prevalence periods and using the DSM-5, the prevalence of CUDs in people who use medicinal cannabis was estimated at 25% (CI: 18-33%). CONCLUSIONS: The prevalence of CUDs in people who use medicinal cannabis is substantial and comparable to people who use cannabis for recreational reasons, emphasizing the need for ongoing research to monitor the prevalence of CUDs in people who use medicinal cannabis.

How much cannabis is used in a joint in Australia? An experimental investigation into use by potency and frequency.

INTRODUCTION: Cannabis use is highly prevalent in Australia, yet current survey metrics measure tetrahydrocannabinol (THC) exposure with limited accuracy. Often survey items measure cannabis quantity by assuming specific modes of use (i.e., 'how many joints do you use?'), which fail to capture variations in cannabis use and the diverse modes of use (e.g., joints, cones, spliffs). This study investigated how much cannabis is used in these modes of administration in an Australian sample. METHODS: Participants (N = 31, Mage = 25.77; 51% university students) completed the Roll a Joint Paradigm in which they rolled joints, spliffs and packed cones as they would typically, using oregano as 'cannabis.' Participants then prepared each again but with cannabis of higher or lower potency. RESULTS: The amount of cannabis used across different modes of administration was variable: joints (range 0.10-1.25 g), spliffs (range 0.12-1.21 g) and cones (range 0.03-0.41 g). Participants who used cannabis daily rolled three times the amount of cannabis into a joint. DISCUSSION AND CONCLUSIONS: The amount of cannabis used in common modes of administration may be highly variable. Daily use may be associated using larger quantities of cannabis. Titration attempts based on potency were not proportional or consistent across modes of administration. The results indicate people may adjust the quantity of cannabis based on perceived potency, however, not proportional to THC concentration. Inconsistency in the amount of cannabis used based on potency and within different modes of administration may represent a problem for self-report metrics which ask participants to report cannabis use in joints.

Prevalence and correlates of positive parental attitudes towards cannabis use and use intention in Australia during 2016 and 2019.

INTRODUCTION: With recent policy changes around medicinal cannabis in Australia, there is concern about the influence of changing norms of cannabis use on adults who are actively parenting. METHODS: This repeated cross-sectional population study used National and Drug Strategy and Household Surveys to estimate the changes and correlates of cannabis-related attitudes (support of legalisation, approve of regular use, would try or use if legal) among Australian parents from 2016 to 2019. RESULTS: The estimated proportion of parents who supported legalisation and approved regular cannabis use increased significantly. Parents who would try cannabis if it was legal grew from 5.9% (95 %CI: 5.2, 6.7) to 8.1% (95 %CI: 7.2, 9.0). Parents who said they would use cannabis more often increased from 1.6 (95 % CI: 1.2, 1.9) to 2.9 (95 %CI: 2.4, 3.4), an 81% jump in the three years. The strongest associations were observed between a very high level of psychological distress and regular smoking and drinking. For example, people with a very high level of psychological distress were 2.16 times (95 %CI: 1.42, 3.28) and 2.48 times (95 %CI: 1.61, 3.83) more likely to approve legalisation and regular cannabis use, respectively. Daily drinking was associated with higher odds of trying cannabis (OR = 1.66; CI: 1.25-2.20). DISCUSSION AND CONCLUSION: The proportion of parents who would try or use cannabis more often represents a sizeable pool of potential new and frequent users. This highlights the need for education and intervention strategies for parents who use cannabis and care for young children. The associations between mental health and substance use suggest that more research is needed to understand the impact of legalisation on vulnerable groups.

Promotions of vaping products near schools and central business district: A descriptive cross-sectional study.

ISSUES ADDRESSED: The increase of youth vaping in Australia has raised concerns, especially with increasing promotions of vaping products. We observed the visibility of vaping products near high-adolescent-traffic areas. METHODS: We examined stores within walking distance of high schools and the central business district (CBD) in Brisbane, Australia, observing the number and proportion of stores selling or displaying vaping products. Using an observational approach, we analysed advertisements and open displays of vaping products at tobacconists, vape stores, and convenience stores. RESULTS: We identified 61 eligible stores located near schools or in the CBD. Overall, 20% of stores displayed vaping products externally, with higher proportions among vape stores (78%) compared to tobacconists (36%). Additionally, 46% of stores had visible interior displays, with vape stores (89%) displaying them more frequently than tobacconists (71%). Among the 28 stores displaying vaping products, 57% included warnings, one store featured only flavoured products, and 25% showcased nicotine-containing products. Youth-appealing features were present in all but one store, with cartoons (61%) as the most common feature. CONCLUSION: Vapes were displayed near high schools and in the city, often featuring youth-appealing features, such as colours and flavours. SO WHAT?: The exposure to such promotions could normalise vaping and contribute to increased youth uptake. Continued monitoring of vaping product promotions is essential, particularly considering recent policy changes.

The implementation and public health impacts of cannabis legalization in Canada: a systematic review.

AIMS: We provide a narrative summary of research on changes in cannabis arrests, cannabis products and prices, cannabis use and cannabis-related harm since legalization. METHODS: We systematically searched for research on the impacts of cannabis legalization in Canada in PubMed, Embase, Statistics Canada and government websites and Google Scholar, published between 2006 and 2021. RESULTS: Cannabis legalization in Canada has been followed by substantial reductions in cannabis-related arrests and cannabis prices. It has also increased adults' access to a diverse range of cannabis products, including edibles and extracts. The prevalence of cannabis use among young adults has increased, but there have been no marked increases or decreases in use among high school students or changes in the prevalence of daily or near-daily use. Legalization has been associated with increased adult hospital attendances for psychiatric distress and vomiting, unintentional ingestion of edible cannabis products by children and hospitalizations for cannabis use disorders in adults. There is conflicting evidence on whether cannabis-impaired driving has increased since legalization. There is suggestive evidence that presentations to emergency departments with psychoses and cannabis use disorders may have increased since legalization. CONCLUSIONS: Legalization of cannabis in Canada appears to have reduced cannabis arrests and increased access to a variety of more potent cannabis products at lower prices. Since 2019, recent cannabis use in Canada has modestly increased among adults but not among adolescents. There is evidence of increased acute adverse effects of cannabis among adults and children.

Association between pediatric TBI and mental health and substance use disorders: A scoping review.

BACKGROUND: The relationship between pediatric Traumatic Brain Injury (TBI) and long-term mental health and substance use disorders is not well known, resulting in inadequate prevention and management strategies. The aim of this scoping review is to review the evidence on pediatric TBI and the development of mental health disorders and substance use later in life and to identify gaps in the literature to inform future research. METHODS: We searched multiple databases for original articles published between September 2002 and September 2022 on TBI-related mental health and/or substance use disorders in children and youth. Two independent reviewers performed the screening using Arksey and O'Malley and Levac et al.'s scoping review framework. RESULTS: A total of six papers are included in this scoping review. Studies included are comprised of cross-sectional and prospective longitudinal cohort studies. DISCUSSION: A correlation between pediatric TBI and development of certain mental health disorders and substance use is suggested, although much of the current evidence is mixed and does not account for confounding variables. Future studies should aim to closely examine these links and identify modifiers that can influence these relationships.

Prevalence and correlates of cannabis use for medicinal reasons - An Australian cross-sectional study.

Objective: It is important to know the prevalence and source of medicinal cannabis use in the population because non-prescribed medicinal use of cannabis products places individuals at higher risk of harms. We estimated the prevalence and correlates of the use of cannabis for medicinal purposes in Australia, three years after Australians were given legal access. Design: Cross-sectional. Setting: The 2019 Australian National Drug Strategy Household Survey. Participants: Participants were 22,015 Australians aged 14 or above. Outcome measure: Self-reported cannabis use in the last 12 months for medicinal purposes only, both medicinal/recreational reasons, or recreationally only. Those who reported medicinal use were asked if it had been prescribed by a doctor. Prevalence estimates were weighted to the population and multinomial logistic regression examined the correlates. Results: The prevalence of any medicinal cannabis use in the past year was 2.6%. Only 0.8% of the sample reported using cannabis solely for medicinal reasons, 95.9% of whom did not have a prescription. A self-reported diagnosis of cancer was associated with medicinal use only. Self-reported chronic pain was associated with both medicinal only and medicinal/recreational use. Medicinal cannabis use was associated with opioids use. Conclusions: In 2019, the prevalence of cannabis use solely for medicinal reasons remains under 1%, was more common among people with specific medical conditions, but most individuals do not have a prescription. The prevalence of self-reported medicinal cannabis use in Australia is low and there is limited use of the legal pathway for medicinal cannabis.

Childhood maltreatment and disordered eating: The mediating role of emotion regulation.

Childhood maltreatment is pervasive and can result in life-long adverse physical and mental health challenges, including a heightened risk for disordered eating. Current treatments for disordered eating have limited long-term success, partly because the psychological processes involved are not well understood. The current research examined two different components of emotion regulation (expressive suppression and cognitive reappraisal) and three components of cognitive emotion regulation (intrusive thoughts, thought suppression attempts, and successful thought suppression) as potential psychological mechanisms mediating the relationship between various forms of childhood maltreatment and disordered eating behaviours. Data was drawn using an online survey in an Australian community sample. In total, 461 individuals participated (76.80 percent female, M = 43.04 years, SD = 16.23). Participants completed measures for childhood maltreatment (Childhood Trauma Questionnaire - Short Form), disordered eating behaviour (Three Factor Eating Questionnaire - Revised 21), emotion regulation (Emotion Regulation Questionnaire) and thought suppression (Thought Suppression Inventory - Revised). Bootstrapping tests revealed significant mediation pathways between all forms of childhood maltreatment (physical, emotional and sexual abuse, and physical and emotional neglect), and eating behaviours (cognitive restraint, uncontrolled eating and emotional eating), through the emotion regulation strategies of cognitive reappraisal, intrusive thoughts and successful thought suppression. Further longitudinal studies are needed to clarify the direction of causality in these findings of emotion regulation strategies mediating the relationships between childhood maltreatment and disordered eating behaviours.

Do Cannabis Users Reduce Their THC Dosages When Using More Potent Cannabis Products? A Review.

Background: Higher potency cannabis products are associated with higher risks of negative physical and psychological outcomes. The US cannabis industry has opposed any restrictions on THC levels, arguing that people titrate their THC doses when consuming higher potency products. Objective: To review research on the degree to which people who use cannabis for recreational purposes can and do titrate their THC doses. Method: A systematic search was conducted for studies published from 1973 to 2020. We included (1) experimental laboratory studies on dose titration of cannabis products that varied in THC content; (2) observational studies on the use of more potent products; and (3) surveys on whether cannabis users titrate when using more potent products. Results: In some experiments, there were inverse associations between the THC content and the amount smoked and smoking topography, while others indicated higher doses consumed and psychological and physiological effects observed. Findings of observational studies of regular cannabis users were more equivocal. In some surveys, cannabis users reported that they use less when using more potent products, but in other surveys, persons who used more potent cannabis had more adverse effects of use. Discussion: There is some evidence from experimental studies that people who use higher potency cannabis for recreational purposes can titrate their THC doses, but less evidence that regular cannabis users do in fact do so. We need much better experimental and epidemiological research to inform the design of regulatory policies to minimize harms from the use of high THC cannabis products.

Engaging a person with lived experience of mental illness in a collaborative care model feasibility study.

Researchers have explored different types of treatment to help people with a mental illness with other problems they might be experiencing, such as their health condition and quality of life. Care models that involve many different health care providers working together to provide complete physical and mental health care are becoming popular. There has been a push from the research community to understand the value of including people with lived experience in such programs. While research suggests that people with lived experience may help a patient's treatment, there is little evidence on including them in a team based program. This paper describes how our research team included a person with lived experience of psychosis in both the research and care process. We list some guiding principles we used to work through some of the common challenges that are mentioned in research. Lastly, experiences from the research team, lessons learned, and a personal statement from the person with lived experience (AA) are provided to help future researchers and people with lived experience collaborate in research and healthcare. Background In our current healthcare system, people with a mental illness experience poorer physical health and early mortality in part due to the inconsistent collaboration between primary care and specialized mental health care. In efforts to bridge this gap, hospitals and primary care settings have begun to take an integrated approach to care by implementing collaborative care models to treat a variety of conditions in the past decade. The collaborative care model addresses common barriers to treatment, such as geographical distance and lack of individualized, evidence-based, measurement-based treatment. Person(s) with lived experience (PWLE) are regarded as 'experts by experience' in the scope of their first-hand experience with a diagnosis or health condition. Research suggests that including PWLE in a patient's care and treatment has significant contributions to the patient's treatment and overall outcome. However, there is minimal evidence of including PWLE in collaborative care models. This paper describes the inclusion of a PWLE in a research study and collaborative care team for youth with early psychosis. Aims To discuss the active involvement of a PWLE on the research and collaborative care team and to describe the research team's experiences and perspectives to facilitate future collaborations. Method This paper describes the inclusion of a PWLE on our research team. We provide a selective review of the literature on several global initiatives of including PWLE in different facets of the healthcare system. Additionally, we outline multiple challenges of involving PWLE in research and service delivery. Examples are provided on how recruitment and involvement was facilitated, with the guidance of several principles. Lastly, we have included a narrative note from the PWLE included in our study, who is also a contributing author to this paper (AA), where she comments on her experience in the research study. Conclusion Including PWLE in active roles in research studies and collaborative care teams can enhance the experience of the researchers, collaborative care team members, and PWLE. We showcase our method to empower other researchers and service providers to continue to seek guidance from PWLE to provide more comprehensive, collaborative care with better health outcomes for the patient, and a more satisfying care experience for the provider.

Deeply Discrediting: A Systematic Review Examining the Conceptualizations and Consequences of the Stigma of Working in Aged Care.

BACKGROUND AND OBJECTIVES: The stigma of working in aged care can discredit and devalue those working in gerontology. This overlooked workforce issue may underpin complex staffing challenges like chronic worker shortages and inadequate care delivery. Our review synthesizes the existing literature and introduces a conceptual framework based on linguistics to reconcile disparate conceptualizations and negative consequences of this stigma. RESEARCH DESIGN AND METHODS: We conducted a systematic review and assessed peer-reviewed articles published from 1973 to 2019 across 5 databases. Fifty-nine articles were selected based on criteria grounded in stigma theory. RESULTS: Only 10 articles explicitly used the term "stigma" when conceptualizing the stigma of working in aged care. An additional 49 articles conceptualized this stigma in terms of stigma processes (e.g., status loss). Findings from a deeper examination using a linguistic analysis revealed societal groups predominantly conceptualized stigma in 3 distinct ways based on (a) unfavorable character judgment of aged care workers, (b) lower value placed on aged care work, and (c) negative emotional reactions towards working in aged care. Last, stigma was associated with adverse psychological and job-related consequences. DISCUSSION AND IMPLICATIONS: Reconceptualizing this workforce issue and recognizing it as a societal challenge will enable policymakers to design evidence-based interventions at industry and societal levels. We propose workforce challenges in the aged care sector such as attraction, retention, and well-being may lessen with interventions aimed at mitigating the stigma of working in aged care.

Food Addiction and Tobacco Use Disorder: Common Liability and Shared Mechanisms.

As food addiction is being more commonly recognized within the scientific community, parallels can be drawn between it and other addictive substance use disorders, including tobacco use disorder. Given that both unhealthy diets and smoking are leading risk factors for disability and death, a greater understanding of how food addiction and tobacco use disorder overlap with one another is necessary. This narrative review aimed to highlight literature that investigated prevalence, biology, psychology, and treatment options of food addiction and tobacco use disorder. Published studies up to August 2020 and written in English were included. Using a biopsychosocial lens, each disorder was assessed together and separately, as there is emerging evidence that the two disorders can develop concurrently or sequentially within individuals. Commonalities include but are not limited to the dopaminergic neurocircuitry, gut microbiota, childhood adversity, and attachment insecurity. In addition, the authors conducted a feasibility study with the purpose of examining the association between food addiction symptoms and tobacco use disorder among individuals seeking tobacco use disorder treatment. To inform future treatment approaches, more research is necessary to identify and understand the overlap between the two disorders.

Evaluating a model of delivering specialist palliative care services in rural New Zealand.

INTRODUCTION Various methods of delivering specialist palliative care to rural areas have been discussed in the literature, but published evaluations of these models are sparse. This study surveyed the stakeholders of a rural specialist palliative care service (SPCS) to help identify potential gaps and inform planning regarding the future vision. METHODS A survey was sent to all relevant stakeholders across the West Coast of New Zealand, including staff in primary care, aged residential care and the hospital. It focused on understanding the local model of palliative care, the quality of the current service and perceived gaps. RESULTS Thirty-three per cent of the surveys were returned, from a cross-section of health-care providers. The medical respondents rated the quality of the service higher than nursing and allied health participants. All of the groups reported feeling the specialist palliative care team (SPCT) was under-resourced. Additional educational opportunities were considered essential. DISCUSSION Stakeholders found the service easy to access, but improvements in communication, educational opportunities and forward planning were identified as being needed. This information helps the West Coast SPCT plan its future direction and develop a higher-quality service that meets the needs of all stakeholders.
