that legal repressiveness may have little deterrent on drug injection and may have a high cost in terms of HIV and perhaps other diseases among injectors and their partners - and that alternative methods of maintaining social order should be investigated, the authors concluded.
That would be because their research showed no correlation between injecting drug use and "legal repressiveness" but did show a positive correlation between law enforcement activities and the incidence of HIV in the IDU population.
It's food for thought anyway.
