South African Dental Journal, 69 (1): 21029-4864http://hdl.handle.net/10566/2237Substance abuse is an escalating health problem. Apart from the serious consequences experienced by drug users, such abuse negatively affects the operational activities of law enforcement officers, teachers and health care workers.
