Searching for specific quote?

Question

I'm looking for the origin of a quote.

It goes something like "You always look happy at the beginning of an addiction."

And I could swear that it was between two people talking. I remember a second person asking "then what happens?" and the guy replying "then you die."

If anyone can tell me where this is from, or if i even have it right.. I'd greatly appreciate it.
