"Getting homeless problem drug users into stable accommodation is the first step towards stabilisation and rehabilitation. Based on the estimated numbers of problem drug users and the proportion of homeless people among clients in treatment, there are approximately 75,600 to 123,300 homeless problem drug users in Europe. As facilities are currently available in most countries, and as some countries continue to implement new structures, the effect of these measures will depend on ensuring that homeless problem drug users can access these services."
