While there is increased recognition of the role of family carers in supporting adults with social care needs, some groups of carers are overlooked or hidden from professional view. Carers of people with substance misuse problems may be among this group since they are at risk of feeling guilty and stigmatised; targeting and eligibility criteria may concentrate professionals’ activities on people with high levels of need for practical support and there may be complex family dynamics where the role of carer does not fit traditional models.
