Heroin Offenses in the EU, Trends 1999-2004
"Over the same five-year period, the number of 'reports' and/or the proportion of drug law offences involving heroin decreased in the majority of reporting countries, except Belgium, Austria, Slovenia and Sweden, which reported upward trends in the number of 'reports' involving heroin and/or the proportion of drug offences that involved heroin.
"The opposite trend can be observed for cocaine-related offences: in terms of both number of 'reports' and the proportion of all drug offences, cocaine-related offences have increased since 1999 in most reporting countries. Bulgaria is the only country to report a downward trend in cocaine offences (both numbers and proportions of drug offences)."
