Sure, there's the advertising, but the drugs themselves are inert in the sense that it's how they're used that influences whether they're being used wisely and safely or incorrectly and dangerously.
In terms of drug advertising, such as erectile dysfunction drugs and so on, what some manufacturers would say is that advertising the drugs provides information to consumers. The style of ad we see in the U.S. gives you information about the drug and provides some information about the side effects. That's a regime that's currently not allowed in Canada.
I forget the second part of your question.
