RESUMO
The National Center for Complementary and Integrative Health (NCCIH), a component of the National Institutes of Health (NIH), has a broad interest in the study of the biological activities of natural products with a strong research emphasis on products for which there is compelling preclinical evidence for potential biological activity that may lead to a health benefit or treatment interventions, and/or products that are widely used by the American public. Use of cannabis for medical purposes is legal in 38 states and the District of Columbia. As a result, the use of cannabis products to treat medical conditions in the United States continues to climb without sufficient knowledge regarding risks and benefits. In keeping with NCCIH's natural product research priorities and in recognizing this gap in knowledge, NCCIH formally launched a research program in 2019 to expand research on the potential therapeutic benefit of minor cannabinoids and terpenes for the treatment of pain. This Viewpoint provides additional details and rationale for this research priority at NCCIH. In addition, NCCIH's efforts and initiatives to facilitate and coordinate an NIH research agenda focused on cannabis and cannabinoid research is described. Significance Statement Trends in the use of cannabis products to treat medical conditions continues without sufficient knowledge regarding risks and benefits. Research is needed to help the public and health care providers make informed decisions about cannabis and cannabinoids for medical purposes. NCCIH along with other NIH Institutes, Centers and Office is expanding its study on the safety, efficacy, and harms of cannabis; a complex mixture of phytochemicals that need to be studied alone and in combination.
RESUMO
Significant changes have occurred in the policy landscape surrounding cannabis legalization, production, and use around the globe and across the United States. With widespread availability of novel cannabis and cannabis-based products, there is an urgent need to understand their safety and effectiveness for medical indications. Three primary barriers contribute to the difficulty in initiating research geared toward answering the most pressing public health questions: the US regulatory status of cannabis and cannabinoids, sources for cannabis and cannabinoid study medications, and limited funding and resources to support studies. Despite these hurdles, research is rapidly increasing, and recent changes in the United States have paved the way for exciting new work. Here, challenges and barriers to cannabis and cannabinoid research are described from the perspectives of the National Institute on Drug Abuse, National Institutes of Health; the US Food and Drug Administration; and 2 clinical researchers. Barriers specifically to studying cannabis, cannabinoids, and cancer are emphasized.

As of April 2020, 121 individuals from 47 nations had completed 124 NIDA International Program INVEST Drug Abuse Research Fellowships. This is the first comprehensive effort to assess the fellowships from the combined perspectives of career outcomes, migration patterns, publications, cost per publication, and funding. We searched electronic sources such as university websites, ResearchGate, LinkedIn, PubMed, and NIH databases to find current curriculum vitae, journal articles published in 2018 and 2019, and funding records. We found electronic records for 94.2% of former NIDA INVEST fellows (n = 114); 55.5% were male (n = 67). The majority are at least partially involved in addiction research, prevention, or treatment (85.9%; n = 98), primarily at academic institutions (73.7%, n = 84) as faculty members (65.8%, n = 75) conducting research (86%, n = 98). Nearly three-fourths (74.6%, n = 85) are still working in their home countries; and 74.6% (n = 85) coauthored at least one research article indexed in PubMed during 2018 or 2019. Of the 656 unique research articles, 52.4% (n = 344) were published by multinational groups. The average cost to NIDA for each peer-reviewed publication was $19,677. More than half (53.5%, n = 61) of the fellows received funding through 431 unique grants-led by NIDA (55), other NIH Institutes and Centers (57) and other U.S. funders (55). Using the measures of career outcomes, migration patterns, publications, cost per publication, and funding INVEST fellowships are cost-effective mechanisms to advance scientific knowledge, build addiction research capacity, foster international cooperation, and promote adoption of evidence-based addiction policies and interventions around the world.

PURPOSE OF REVIEW: For more than 25 years, the National Institute on Drug Abuse (NIDA) has supported research-training programs, establishing a global research network and expanding the knowledge base on substance use disorders. International research to inform approaches to opioid addiction is particularly important and relevant to the United States, where opioid misuse, addiction, and overdose constitute an emerging public health crisis. This article summarizes the NIDA International Program and illustrates its impact by reviewing recent articles about treatment approaches for opioid use disorders (OUD). RECENT FINDINGS: Studies in several countries have demonstrated the effectiveness of physician office-based opioid substitution therapies. Other research has demonstrated the effectiveness of different formulations and doses of the opioid antagonist naltrexone, as well as different approaches to providing naloxone to treat opioid overdose. Continuing research into implementation of evidence-based treatment in international settings with limited resources is applicable to US regions that face similar structural, legal, and fiscal constraints. SUMMARY: The current review describes international research on OUD treatment and opioid overdose, most coauthored by former NIDA fellows. The findings from outside the United States have important implications for best practices domestically and in other countries that are experiencing increases in OUD prevalence and related overdose deaths.

Over the past decade, the amount and variety of addiction research around the world has increased substantially. Researchers in Australia, Canada, United Kingdom, United States, and western Europe have significantly contributed to knowledge about addiction and its treatment. However, the nature and context of substance use disorders and the populations using drugs are far more diverse than is reflected in studies done in Western cultures. To stimulate new research from a diverse set of cultural perspectives, the National Institute on Drug Abuse (NIDA) has promoted the development of addiction research capacity and skills around the world for over 25 years. This review will describe the programs NIDA has developed to sponsor international research and research fellows and will provide some examples of the work NIDA has supported. NIDA fellowships have allowed 496 individuals from 96 countries to be trained in addiction research. The United Arab Emirates and Saudi Arabia have recently developed funding to support addiction research to study, with advice from NIDA, the substance use disorder problems that affect their societies. Examples from Malaysia, Tanzania, Brazil, Russian Federation, Ukraine, Republic of Georgia, Iceland, China, and Vietnam are used to illustrate research being conducted with NIDA support. Health services research, collaboratively funded by the U.S. National Institutes of Health and Department of State, addresses a range of addiction service development questions in low- and middle-income countries. Findings have expanded the understanding of addiction and its treatment, and are enhancing the ability of practitioners and policy makers to address substance use disorders.

New scientific knowledge and effective, evidence-based interventions have provided health leaders and policymakers a remarkable paradigm to guide the development of addiction treatment services around the world. The definition of addiction as a brain disease, validated screening and assessment tools, medication-assisted treatment, and effective behavioral treatments have served as vehicles for both the United States and other countries to guide the transformation of their substance abuse treatment systems. Seeking to expand international research and infrastructure, the National Institute on Drug Abuse (NIDA)'s International Program has engaged international investigators and institutions in addiction research to promote dissemination of addiction science globally. This paper presents three mixed-methods case studies to exemplify the use of advancements in evidence-based practice in addiction treatment as guides and tools for the creation or further development of treatment systems in three countries, Vietnam, Lebanon, and Abu Dhabi. Results indicate that a framework of evidence-based medicine and empirical science creates a necessary platform from which objective conversations about addictions may begin. Other facilitative factors that help create treatment programs internationally include: a receptive and supportive government, support from international donors and technical experts, networking and interest from other international organizations, and often a synergistic and concerted effort by multiple entities and partners. Despite substantial differences in the circumstances that generated these initiatives and the varying scope of the services, common themes across these efforts have been the implementation of science-based approaches to systems transformation and support for a public health approach to addressing drug abuse and addiction.
RESUMO
This special issue of Substance Use & Misuse addresses the public health issue of volatile substance misuse (VSM), the inhalation of gases or vapors for psychoactive effects, assessing the similarities and differences in the products misused, patterns, prevalence, etiologies, and impacts of VSM by examining it through sociocultural epidemiology, neuroscience, and interventions research. The Canadian, US, and Australian guest editors contend that, when compared with other drugs used at a similar prevalence, VSM has attracted relatively little research effort. The authors and editors call for further research to develop evidence-based policies and comprehensive interventions that respect culture and context-specific knowledge.
