“…In accordance with socioecological models, stigmatising public attitudes are reinforced by (drug) policy, laws, societal structures, and the media, and may be reproduced through the practices of some institutions and professionals (da Silveira et al, 2018;Gilchrist et al, 2011;Russell et al, 2011;Skinner et al, 2007;Soh et al, 2019;Stangl et al, 2019;van Boekel et al, 2013;von Hippel et al, 2008). This can undermine provision, access, and the quality of drug treatment, and may reinforce discrimination and broader health and social inequity (Andersen & Kessing, 2019;Lancaster et al, 2017;Rivera et al, 2014;Smith et al, 2016). People who use drugs (PWUD), including those in receipt of treatment, report that perceptions and experiences of public and internalised stigma can lead to reduced self-worth and label avoidance, and act as a barrier to treatment seeking and recovery (Biancarelli et al, 2019;Birtel et al, 2017;Chan Carusone et al, 2019;Luoma et al, 2007;Neale et al, 2011;Stringer & Baker, 2018).…”
