In delinquency, connected with alcohol, the immediate and acute effect of the substance is prominent, whereas in delinquency connected with drugs, one has to deal with chronic effects. The criteria for judging drunken offenders also stand as a model for judging the responsibility of the addicted offender for his crime. We consider: 1. the personality of the offender 2. the way, the amount and the point of time of the last intake of the drug 3. the potential dependence 4. the psychopathological state at the time of offense and at the time of examination 5. the kind of the offense itself. Most cases, which have to be examined, deal with indictable offenses, which were undertaken, in order to get new supply, i.e. "supply-offenes". These cases surmise, that the offender is physically addicted, that he knows about withdrawal symptoms from own experience, and that he committed the crime purely for securing his personal supply. We differentiate between direct "supply-offenses" (i.e. direct stealing by the addict himself) and indirect "supply-offenses" (i.e. mainly trading and commission business). For the latter offenses the state of consciousness and insight at the time of offense does not serve as a suitable criterion for judging the responsibility for the crime, since these offenders usually are not deprived of their drugs and therefore in a stable state of mind. Therefore the inner situation and the motivation for carrying out the crime has to be analysed carefully. For these indirect "supply-offenses" reduced responsibility for the offense has to be considered, whereas for direct "supply-offenses" a total lack of responsibility can be assumed.
