My first impulse was it’s not the same effect, but thinking of it some more I see what you mean. The main problem with it is convincing everyone that fb actually sells a drug and not entertainment/news.

Otoh, if you find out that you’re selling drugs in your cookie shop, should you stop? Because even non-targeting news sites do exactly that in this analogy. They post articles that “everyone” wants to see. Where is a borderline between “free coffee to breakfast” and “heroin store black friday”?
