This report concludes that street level heroin prices remained relatively stable, but purity levels fell. There were reports that during this time, heroin use decreased with some users switching to or increasing their use of other substances, particularly benzodiazepines and alcohol.
During the period of reduced supply, new presentations to drug treatment for opiate use fell and there were no significant changes in drug related acquisitive crime, though there was a decline in heroin possession offences.
