Psychosocial interventions are the mainstay of treatment for cannabis misuse for people of all ages. 'Drug misuse and dependence UK guidelines on clinical management (2007)' notes that there are no medications suitable for treating cannabis misuse and advises that clinicians should consider psychosocial interventions, especially brief motivational interventions in mild cases. More heavily dependent misusers may require structured treatment. In cases of co-morbidity with depression and anxiety, treatment will include cognitive behavioural therapies.
With regard to under-18s, local authorities will be supported in carrying out a local needs assessment and planning for the full range of services that will respond to young people's substance misuse needs, and also enable them to have clear protocols in place to meet the needs of vulnerable young people.
