controversial scheme to give addicts heroin at supervised clinics has led to a reduction in crime. More than a hundred addicts took part in the scheme in London, Brighton and Darlington which was part funded by the government. http://news.bbc.co.uk/1/hi/uk/8254872.stm
Here's a report by Danny Shaw, the BBC home affairs correspondent:
Is this the right approach to tackling the problem of drugs and crime? If you've been a drug user or the victim of drug related crime are you in favour of this approach? Are you happy with any measures that reduce crime or do you feel that this is an example of society going soft on drug addicts?
In 1994 the Swiss embarked on their Heroin Assisted Treatment project. This resulted in a significant improvement of health (both mentally and physically) for the majority of the over 1200 participants. In addition, a massive reduction in criminal behavior was observed.The HAT outpatient centers are spread over the following Swiss cities : Basel, Bern, Biel, Brugg, Burgdorf, Chur, Geneva, Horgen, Lucerne, Olten, Reinach, Schaffhausen, Solothurn, St. Gallen, Thun, Winterthur, Wetzikon, Zug, Zürich and in two prisons Oberschöngrün (canton Solthurn) and Realtà
The Swiss Federal office for public health reports that :
In many cases, patients’ physical and mental health has improved, their housing situation has become considerably more stable, and they have gradually managed to find employment. Numerous participants have managed to reduce their debts. In most cases, contacts with addicts and the drug scene have decreased. Consumption of non-prescribed substances declined significantly in the course of treatment.
Dramatic changes have been seen in the situation regarding crime. While the proportion of patients who obtained their income from illegal or borderline activities at the time of enrollment was 70%, the figure after 18 months of HAT was only 10%.Each year, between 180 and 200 patients discontinue HAT. Of these patients, 35-45% are transferred to methadone maintenance, and 23-27% to abstinence-based treatment.The average costs per patient-day at outpatient treatment centers in 1998 came to CHF 51. The overall economic benefit - based on savings in criminal investigations and prison terms and on improvements in health - was calculated to be CHF 96. After deduction of costs, the net benefit is CHF 45 per patient-day.
