Opioid agonist treatment (OAT) is an important pillar in the treatment of individuals using opioids and its continuation during imprisonment is recommended. Despite this knowledge access to and continuation of OAT is still limited in many countries. The forced discontinuation during pre-trial detention can cause severe withdrawal symptoms, which in turn may significantly impair the defendant's ability to exercise granted procedural participation rights. Furthermore, it can be argued that forced discontinuation of a desired treatment represents a form of a compulsory intervention.
