Figure DLO-3. Indexed trends in reports for drug law offences by type of drug in the EU Member States, 2004–09


1. The trends represent the available information on the national number of reports for drug law offences (criminal and non-criminal) reported by all law enforcement agencies in the EU Member States; all series are indexed to a base of 100 in 2004 and weighted by country population sizes to form an overall EU trend; the figures between brackets refer to the total number of offences as reported in 2009 (before weighting).

2. The general term 'reports for drug law offences' is used, since definitions and study units differ widely between countries. For definitions of the term 'reports for drug law offences', please refer to <a href="https://www.emcdda.europa.eu/stats11/DLO/methods">Drug law offences - methods and definitions</a>.

3. Countries that in 2007 carried out changes in the information system likely to affect comparability across time (Estonia, Ireland, Latvia, Luxembourg and Slovakia) as well as countries with missing data for two or more consecutive years are not included in the trend calculations. The trend line for both heroin and cocaine is based on 16 countries (83 % of the EU population 15-64), for cannabis on 16 (87 % of the EU population 15-64), for amphetamine on 13 (79 % of the EU population 15-64) and for ecstasy on 15 (82 % of the EU population 15-64).

4. Additionally, where 2009 data are missing (2 countries) 2008 data are used, for missing 2004 data (2 countries) 2005 data are used.

5. Cyprus and Portugal were not included in the trend calculation for amphetamine due to low number of cases reported.
