Quark: What's that disgusting smell?
Nog: I think it's called 'tobacco'. It's a deadly drug. When used frequently, it destroys the internal organs.
Quark: If it's so deadly, then why do they use it?
Nog: It's also highly addictive.
Rom: How do they get their hands on it?
Nog: They buy it in stores.
Quark: They buy it? If they'll buy poison, they'll buy anything. I think I'm going to like it here.
