There are plenty of people who take homeopathic and other alternative products instead of prescription products because they can't afford the prescription products, and fraudulent advertising makes them think the alternative is more or less equivalent.

I actually had someone at a pet store try to sell me homeopathic medication instead of dewormer because they were out of actual dewormer. Do you think that's harmless to someone who doesn't know the difference between giving their pet real medication vs. magic woo water?
