Summary
The use of substitution drugs for
the treatment of opioid dependence
represents a key evidence-based response
to heroin problems in Europe. However,
the diversion of these medicines from
their intended use in drug treatment to
non-medical use and sale on illicit drug
markets is a cause for concern. The use of
diverted substances has been associated
with fatal and non-fatal overdose
and an increased incidence of opioid
dependence. This analysis summarises
the context of opioid substitution
treatment in Europe, what diversion is
and what current measures are being
implemented to reduce it, and considers
the implications for the future.
