Sharing (borrowing or lending) injection paraphrenia in the month preceding interview was reported by just over half (52%) the sample. Participants who had engaged in this behaviour were more likely to have initiated heroin use via injecting (71% vs 61%, χ2 = 4.37, df = 1, p < .037) and to have recently initiated someone to injecting (12% vs 23%, χ2 = 7.95, df = 1, p < .005) compared to those who not shared injection paraphernalia. There was no difference in terms of age at first heroin injection.
