This makes intuitive sense, anyway: someone who is about to smoke (what turns out to be) their last cigarette before they finally succeed in quitting, does not therefore do a half-assed job of lighting it.

True at least in lab conditions (it's harder to measure force in real world conditions), but this isn't an extinction process. The antecedent of losing something is still present; the consequence is less clear but there's no indication it has changed. Counseling could be seen then as positive reinforcement of an alternative, or as positive punishment of getting angry; assuming it causes a change in behavior.

Interesting, I'll take a look around. Google keywords you would use or any links that you might be able to dredge up from a shallow search would be appreciated.
