"Consumption rooms achieve the immediate objective of providing a safe place for lower risk, more hygienic drug consumption without increasing the levels of drug use or risky patterns of consumption.

"Direct benefits of supervised injecting appear to be a reduction in some of the risk behaviours related to injecting, in particular improvements in injecting practice, use of sterile equipment and lack of opportunity for sharing drugs. Other benefits are that, if medical emergencies should occur, immediate medical intervention is possible, and the consumption equipment used in the rooms is correctly disposed of. Client surveys consistently show that service users appreciate the hygienic conditions, safety and peace that the rooms provide."
