Section 57 of the Prevention of and Treatment for Substance Abuse Act, 2008 specifically provides that the MECs must establish Provincial Substance Abuse Forums for their respective provinces. This is not a delegated power but a conferred power by the Act and the Minister cannot interfere with the powers conferred by legislation to her provincial counterparts as this would be in conflict with section 41 of the Constitution of the Republic of South Africa read with the Intergovernmental Relations Framework.
In terms of the same Act, the Minister is only empowered to establish the Central Drug Authority (CDA), which represents the national sphere of government. The Minister therefore does not have any executive or legislative mandate to establish Provincial Substance Abuse Forums and Local Drug Action Committees.
Provincial MECs are better placed to respond to this question.
