Table 6 Examples of justifications for exclusion of people who use drugs from research

From: The ethics of community-based research with people who use drugs: results of a scoping review

Citation Justification for exclusion
Aldridge and Charles 2008 [47] Describes assumptions held by researchers that exclusion is justified if a participant is deemed “too intoxicated” to participate (based on biochemical or bio-behavioural screening).
DuBois et al. 2011 [48] Describes how financial resources may limit the number of community members who can be included or involved in research.
Levine et al. 1991 [26] Suggests there is strong evidence to support exclusion if a drug-using participant is ‘a threat to safety’.
Striley et al. 2008 [30] Describes assumptions held by researchers that exclusion is justified because participant may become non-compliant with research protocols or follow-up appointments
