According to a recent report from the Health Research Board, drug poisoning was identified as the cause of death in 48% of cases among people experiencing homelessness in Ireland. The study analyzed data from various sources to examine the relationship between substance use and mortality rates in this group. Researchers found that approximately 90% of individuals who died while homeless had a documented history of substance use. The findings indicate a high prevalence of substance use among people experiencing homelessness and highlight its significant contribution to mortality rates. The report provides evidence of the ongoing public health challenge posed by substance use within the homeless population in Ireland. The study's results may inform future policy and intervention strategies aimed at reducing drug-related deaths and improving health outcomes for people experiencing homelessness.
