The case notes of 69 consecutive intravenous opiate misusers attending
an outpatient treatment unit were reviewed to explore possible factor
s associated with the use of femoral and jugular veins for injection.
A longer history of treatment, a history of parental violence and/or a
buse and evidence of early antisocial behaviour were associated with i
njection into deep veins. Replication of these results and further inv
estigation of the hypothesis generated are recommended.
