People who Inject drugs, as an at-risk population in physical and mental disorders, need support
to reduce harm. This study found that the health-related quality of life of these people is affected
more by the pain and discomfort dimension. This can be caused by their social exclusion and
marginalization. Hence, regular planning is necessary to organize the health status of these
people. Due to the hard-to-reach nature of this population, special arrangements such as utilizing
peer groups may be effective to provide them with services.
