[en] Purpose: In 2013, during a recent heroin-assisted treatment trial, participants in heroinassisted
treatment (HAT) decreased significantly more their street heroin use than
participants in oral methadone treatment. After the trial, HAT was discontinued. To examine
whether the treatment benefits were sustained three months after the trial, the use of street
heroin by the participants was analysed in a follow-up study.
Results: At the follow-up assessment, street heroin use increased in the experimental group.
The two groups no longer showed a significant difference (p=0.55) in the level of street
heroin use.
Conclusion: A predetermined and forced end of HAT was followed by a significant increase
in the level of street level use.
