Drug Offences 95
More differences could be found with regard to the typical forms of personal use
offences (i.e. consumption and possession of small quantities; see table E.3.3).
While the majority of countries included both types in their data, many countries
excluded consumption and/or possession of small quantities. Both types were
excluded from police and conviction statistics in Albania, the Czech Republic, Italy,
Portugal and Russia, probably due to “real” decriminalization of personal use offences.
The same is true in principle for Estonia, where small quantities are only
included in the data if there is intent of trafficking. In Germany, consumption is
fully excluded while possession of small quantities is only excluded on convictions
level (the latter is due to mere procedural decriminalization).
Some other countries only exclude one: consumption (Denmark, Lithuania, Portugal,
Ukraine) or possession of small quantities (Belgium [convictions level only],
the Netherlands), therefore not leading to a full decriminalization of personal use
offences (see also table E.7, below).
