2. 2 Basic question To evaluate drug policies in any country, it is important to have information on three aspects of these policies: 1)to what extent criminal law and criminal justice interventions are directed towards supply of drugs and to what extent towards demand for drugs; 2)to what extent criminal law and criminal justice interventions regarding demand constitute either purely repressive interventions, or involve also alternative measures intended to divert offending drug users to the treatment system; 3)what are the reasons for eventual different patterns;

8. 8 Selection mechanisms in the criminal justice system: „funnel model” Output:number of reported (registered) offences Output: number of prosecutions Output: number of convictions Output: number of people serving prison term Input: number of really committed offences

9. 9 Tasks for the future it may be worth effort to learn more about and to attempt to explain significant differences in outcomes of the selection mechanism and criminal justice interventions between European countries; however, this may be difficult without certain data being available throughout Europe on the national level; targeted data collection and specific research projects may be necessary here;

16. 16 Preliminary conclusions law enforcement effort in most countries seems to concentrate on the use related offences; this is especially visible in some countries ranked quite low on supply related offences, but being champions in use related offences rates, and because of this also champions in general drug offences rates; more precise knowledge is highly desirable about reasons for this pattern; this may be of great importance for evaluating impact of the law enforcement effort on various aspects of the drug problem;

19. 19 Preliminary conclusions attrition rate (difference between registered offences rate and convictions rate) seems to be huge in case of some countries; this suggests that many registered drug offences are never prosecuted, and it never comes to conviction for them; as this rate seems to be generally lower in case of supply related offences, it may mean that use related cases are mostly responsible for that phenomenon; it is highly desirable to know why is it so: are these cases just dropped off for some reasons, or are they diverted to be dealt with in other way?

20. 20 Conclusion gaps in the knowledge about criminal justice interventions in case of drug offences seem to be quite substantial throughout Europe; because of this the need to collect more data and to conduct research in this area seems to be especially acute!
