There has been divergent comments on advertising practices in Nigeria, such comments cover every aspects of advertising including advertising economic effects, social impacts, its truthfulness and deception among others. This research tested whether the opinion expressed by these commentators is a reflection of public opinion on advertising. It was found that public perception of advertising in Nigeria is not too critical overall. However, certain practices of advertising were deplored. Moreover, it was found that a person's attitude toward advertising is independent of either a person's perception of the extent of consumer's degree of vulnerability in a purchase situation or his attitude toward business. A persons attitude toward advertising is however dependent on his/her sex and his/her usage or non-usage of the product being advertised. The study recommends among others that government should enforce that advertisements for alcohols and cigarettes should contains warnings about their possible health implications.
