Part (ii) Methodological notes

CountryMethods of percentages calculation and other notes
BelgiumBetween 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: someone can have more than one drug in his/her possession; not only the main substance is mentioned. Offences without a specified substance are included. These changes are likely to affect comparability across time.
