The purpose of this article is to gain insight in the South African tobacco industry, its influence on the community and the role of anti-tobacco campaigns. This is done by conducting an empirical investigation of the attitudes and behaviour of smokers and non-smokers regarding the national government campaigns against tobacco products. Consequently, it will contribute in determining the efficiency of the anti-tobacco campaigns as well as the effect of the Tobacco Products Control Amendment Act, 1999 (Act 12 of 1999) on smokers and non-smokers. It is postulated that by applying the principles of marketing (demarketing and remarketing) it could contribute significantly in influencing smoking behaviour amongst South Africans.

This study (1) quantitatively compared steroid production in cultured Y-l mouse adrenal tumor cells exposed to Camel and Carlton-smoke derived residues, and (2) localized the effects in the cell. Basal steroid production was increased by Camel residues but not by Carlton, while ACTH stimulation was interfered with by both residues. Camel basal stimulation was comparable to that of cAMP, and was abolished by Cytochalasin D. The stimulation was also comparable to that of cholera toxin, which activates adenyl cyclase. Results indicate that residue components dissolve in the membrane stimulating adenyl cyclase at a point similar to or before that utilized by cholera toxin for its stimulating effect.
