"The municipality is responsible for organising an accident and emergency service to attend to the population’s need for emergency assistance. This includes emergency assistance for people with mental illness and drug or alcohol problems.
"Emergency drug and alcohol treatment facilities have been established in several cities in recent years. The measures are organised differently, and the type of services offered varies. What they have in common is that they are open 24 hours a day, are easily accessible and provide assistance to users in an acute life situation."
