Availability of treatment varies by drug
Problematic users of stimulants (e.g. cocaine and crack) lack access to generally effective treatment.
In Lambeth, for example, an inner London borough with approximately 2,000 drug users in treatment per year, some 93 per cent of all problematic drug users use crack, on its own or in combination with other substances. Seventy per cent of the treatment budget, however, goes to sustaining services for opiate users.
