SIFs and Public Consumption
"Consumption rooms can reduce significantly the level of drug use in public. The extent to which this is achieved depends on their accessibility, opening hours and capacity to accommodate drug consumptions that would otherwise occur in public.
"The location of consumption rooms needs to be compatible with the needs of drug users but also to take account of the needs and expectations of local residents. A reduction in the number of public consumptions can contribute to improvements in the neighbourhood by helping to reduce public nuisance associated with open drug scenes. However, facilities near illicit drug markets are not able to solve wider nuisance problems that result from these markets.
"Police actions against drug markets and drug scenes in other neighbourhoods may sometimes increase public order problems near consumption rooms. This implies that, if rooms are to contribute to reducing public nuisance rather than be blamed for aggravating it, there needs to be consultation not only with local residents but also with police, so that action to discourage open drug scenes does not at the same time deter drug users from making use of the facilities."
