21. Heroin-Assisted Treatment and Decline in Problematic Heroin Use

"Heroin misuse in Switzerland was characterised by a substantial decline in heroin incidence and by heroin users entering substitution treatment after a short time, but with a low cessation rate. There are different explanations for the sharp decline in incidence of problematic heroin use. According to Ditton and Frischer, such a steep decline in incidence of heroin use is caused by the quick slow down of the number of non-using friends who are prepared to become users in friendship chains. Musto's generational theory regards the decline in incidence more as a social learning effect whereby the next generation will not use heroin because they have seen the former generation go from pleasant early experiences to devastating circumstances for addicts, families, and communities later on."

22. Target Population

"As one of the responses to dramatically increasing drug scenes, heroin maintenance trials were implemented in Switzerland from 1994 onwards. The target population for this new treatment consists of heroin users who did not comply with other forms of treatment and who presented serious health and/or social problems."

23. Drug Treatment and Crime Reduction

"With respect to the group of those treated uninterruptedly during four years, a strong decrease in the incidence and prevalence rates of overall criminal implication for both intense and moderate offenders was found. As to the type of offense, similar diminutions were observed for all types of offenses related to the use or acquisition of drugs. Not surprisingly, the most pronounced drop was found for use/possession of heroin. In accordance with self-reported and clinical data (Blaettler, Dobler-Mikola, Steffen, & Uchtenhagen, 2002; Uchtenhagen et al., 1999), the analysis of police records suggests that program participants also tend strongly to reduce cocaine and cannabis use probably because program participants dramatically reduced their contacts with the drug scene when entering the program (Uchtenhagen et al., 1999) and were thus less exposed to opportunities to buy drugs. Consequently, their need for money is not only reduced with regard to heroin but also to other substances. Accordingly, the drop in acquisitive crime, such as drug selling or property crime, is also remarkable and related to all kinds of thefts like shoplifting, vehicle theft, burglary, etc. Detailed analyses indicated that the drop found is related to a true diminution in criminal activity rather than a more lenient recording practice of police officers towards program participants.
"On average, males had higher overall rates than females in the pretreatment period. However, no marked gender differences were found with regard to in-treatment rates. Taken as a whole, this suggests that the treatment had a somewhat more beneficial effect on men than women. This result is corroborated by self-report data (Killias et al., 2002). With respect to age and cocaine use, no relevant in-treatment differences were observed. As to program dropout, after one year, about a quarter of the patients had left the program, and after four years, about 50% had left. Considering the high-risk profile of the treated addicts, this retention rate is, at least, promising."

25. Reasons for Discontinuing Treatment

"Finally, the analysis of the reasons for interrupting treatment revealed that, even in the group of those treated for less than one year, the majority did not actually drop out of the program but rather changed the type of treatment, mostly either methadone maintenance or abstinence treatment. Knowing that methadone maintenance treatment – and a fortiori abstinence treatment – is able to substantially reduce acquisitive crime, the redirection of heroin maintenance patients toward alternative treatments is probably the main cause for the ongoing reduction or at least stabilization of criminal involvement of most patients after treatment interruption. Thus the principal post-treatment benefit of heroin maintenance seems to be its ability to redirect even briefly treated high-risk patients towards alternative treatments rather than back 'on the street'."
