A 55-year-old woman with a 23 pack-year smoking history is taking varenicline (Chantix) and shows generalized staining. Which intervention is most likely to promote successful smoking cessation?

The most effective cessation approach combines counseling/behavioral support with pharmacotherapy (such as varenicline); counseling significantly increases quit rates beyond medication alone.Other options: Switching products, relying on willpower, or treating the staining does not address cessation as effectively as combined counseling plus medication.Key exam takeaway: Smoking cessation works best with counseling PLUS pharmacotherapy (the '5 A's' framework).
