Part (ii) Methodological notes
| Country | Methods of percentages calculation and other notes | |
|---|---|---|
| Belgium | From 2000 to 2002, data refer to the number of persons and only the main offence is reported, although the same person could be counted several times if arrested several times during the same year. | |
| Before 2000 and 2003-2005, data refer to the number of offences and each offence is represented as one separate record in the database. | ||
| Since 2006 data refer to the number of offences and only the main offence and the main substance is mentioned. Offences without a specified substance are included. These changes are likely to affect comparability across time. | ||

| Since July 2001 drug use and possession for use have been decriminalized and made an administrative offence.
