Low threshold services are typically provided within community or city settings, either by statutory or community organisations. Services may be staffed by counsellors, key workers or support workers who would normally seek to engage informally with clients and deliver brief, harm reduction focused interventions. In addition, low threshold services often depend on volunteers for staffing and provide new drugs workers who may require high levels of supervision with an entry point into drugs work. A range of issues have emerged in relation to low threshold service provision including high volumes of clients accessing a service, variation in approach and aims of low threshold services and health and safety implications for workers and clients in regard to service users being severely intoxicated, using substances on the premises or overdosing.
