The Barnabas Charitable Service Association Limited was founded in 1981 by a group of Christians who were inspired by a Bible figure, Barnabas as a comforter for those in need and they chose the female abusers of dangerous drugs as their target group for service.
The agency was registered as a non-profit making organization in 1987 and became a member of the Hong Kong Council of Social Services and the Community Chest subsequently. In 1998, the agency began to receive subvention from the HKSAR government.
