Characteristics of recent drug abuse-related deaths in the city of Sheffiel
d were examined from the coroner's records. Almost all of those who died of
poisoning from a drug of abuse were known to be dependent on heroin yet le
ss than half were receiving treatment. Benzodiazepines were frequently dete
cted alongside opiates during toxicology, the source of which was likely to
be the deceased's own prescription.
