Examining the cost and impact of dosing fees among clients in opioid agonist treatment: Results from a cross‐sectional survey of Australian treatment clients

Introduction Opioid agonist treatment (OAT) clients frequently bear costs associated with their treatment, including dosing fees. This study aimed to explore the financial and social impact of dosing fees upon clients.
