Studies in Europe have suggested that injectable diacetylmorphine, the active ingredient
in heroin, can be an effective adjunctive treatment for chronic, relapsing opioid
In an open-label, phase 3, randomized, controlled trial in Canada, we compared
injectable diacetylmorphine with oral methadone maintenance therapy in patients
with opioid dependence that was refractory to treatment. Long-term users of injectable
heroin who had not benefited from at least two previous attempts at treatment
for addiction (including at least one methadone treatment) were randomly assigned
to receive methadone (111 patients) or diacetylmorphine (115 patients). The primary

status and a reduction in illicit-drug use or other illegal activity according to
the European Addiction Severity Index.
