“…In terms of the regulatory changes, many countries temporarily allowed for more flexible service delivery models in the context of COVID-19, for instance, allowing clients to obtain more takeaway (take-home) doses of methadone and buprenorphine, using telemedicine for reviews and evaluations, accelerating the expansion of long-acting injectables (e.g., depot buprenorphine), delivering medications to clients where possible, extending the duration of prescriptions, and increasing access to take-home naloxone (British Columbia Centre on Substance Use, 2020; Farhoudian et al, 2020; Lintzeris et al, 2020; Substance Abuse and Mental Health Services Administration [SAMHSA], 2020). Despite some concerns around policy implementation (Becker et al, 2021; Pérez-Chiqués et al, 2021), early evaluations suggest that these regulatory changes have led to few if any unintended consequences (Brothers et al, 2021; Caton et al, 2021; Kitchen et al, 2022; Lintzeris et al, 2021; Saloner et al, 2022; Welsh et al, 2022), and clients have reported greater self-efficacy and recovery capital as a result of the increased flexibility in treatment (Levander et al, 2021). There have been calls to sustain and expand these improvements to treatment delivery beyond the pandemic (Corace et al, 2022; Durand et al, 2022; Grebely et al, 2020; Green et al, 2020), and in the US the Substance Abuse and Mental Health Services Administration have recently extended the temporary policy changes for another year, and also have plans to make them permanent (SAMHSA, 2021).…”
