Are some products too dangerous to be marketed in any circumstance? What regulations, if any, would you place on marketing cigarettes? Handguns? Prescription drugs?
As a starting point, refer to The American Marketing Association’s Statement of Ethics, found atwww.marketingpower.com/AboutAMA/Pages/Statement%20of%20Ethics.aspx which provides guidelines for marketing products.
This code of ethics can be used to locate other codes and regulations that may address this issue.
