Taking to someone after cocaine, it isn't just "chat"; it's also a delusion that makes you believe you're saying something very profound, and it's making you look good. You just keep talking.

Coke, in general, is a very bad drug by design. It takes away everything from you and becomes a sole source of happiness.

People lucky and strong enough to survive this can see what was happening to them, especially when they see some other person on coke doing that.
