Who is the drug user activist?: recounting the conceptualisation of drug user activism in the United Kingdom.

The British model of harm reduction has been referenced as a pioneering approach to substance use in Europe. While many have described the development of UK drug policy through different governments, few studies have focused on the role that drug user activists played in the UK drug policy reform movement. We examine the different conceptualisations of UK drug user activists in literature, including published academic journals and grey literature (news articles, podcasts, websites and unpublished dissertations).

Our Voice NOLA: Leveraging a Community Engaged Citizen Science Method to Contextualize the New Orleans Food Environment.

Objective: We employed the Our Voice citizen scientist method using a mobile application (app) to identify and contextualize neighborhood-level features influencing food access and wellbeing in New Orleans, Louisiana.

Design: A three-phase, multi-method study comprised of: (1) a researcher-assisted tag-a-long neighborhood walk (referred to as a 'journey') with the Discovery Tool (DT) app to document neighborhood-level features via geo-coded photos and audio-recorded narratives; (2) a post-journey interview to enable citizen scientists to share their lived experiences; and (3) a community meeting with citizen scientists and local stakeholders.

Setting: Various neighborhoods in New Orleans, Louisiana, USA.

The "Our Voice" Method: Participatory Action Citizen Science Research to Advance Behavioral Health and Health Equity Outcomes.

Citizen science research that more fully engages the community can systematically involve people from under-resourced groups to create practical health-enhancing improvements across physical, social and food environments. Exemplary health equity-focused outcomes include key health behaviors (e.g.

Integrating Photovoice and Citizen Science: The Initiative in Practice.

Community engagement methods like photovoice have allowed researchers to gather and incorporate the experiences and perspectives of community members in their work but have at times faced challenges regarding systematization, accessibility, and scalability. This practice note describes the Our Voice initiative, one example of a community-based participatory research framework that aims to build on photovoice theories and best practices and address these challenges by incorporating the use of a mobile app as well as elements of participatory action-based citizen science to support community-driven data collection, analysis, and advocacy. We explore the application of the Our Voice method and evaluation of multilevel participant and community outcomes across three different Bay Area, California, communities.

Community-Based Approaches to Reducing Health Inequities and Fostering Environmental Justice through Global Youth-Engaged Citizen Science.

Growing socioeconomic and structural disparities within and between nations have created unprecedented health inequities that have been felt most keenly among the world's youth. While policy approaches can help to mitigate such inequities, they are often challenging to enact in under-resourced and marginalized communities. Community-engaged participatory action research provides an alternative or complementary means for addressing the physical and social environmental contexts that can impact health inequities.
