<P> The Central Drug Authority (CDA) was established in 1992, under section 2 of the Prevention and Treatment of the Drug Dependency Act . Its key functions are to effect the National Drug Master Plan; advise the Minister of Social Development on matters affecting substance and drug abuse; and promote measures relating to the prevention and reduction of drug abuse . </P> <P> Since the 1990s, welfare services have been allocated 10% of the Department's overall budget . According to researcher Lisa Vetten, pay increases for the Department's civil servants have been consistently higher than inflation for the past 10 years; these increases have shrunk the budget for provision of services, and have correspondingly diminished funding to the non-governmental organisation (NGO) sector . She argues underfunding has created a two - tier system of care, in which government services are considerably better resourced than NGO counterparts . Further exacerbating NGOs' situations is the Department's late payment of their subsidies . </P>
