Forget doing it for your pets. New research suggests offering cold hard cash is the strongest incentive for smokers to kick their dirty habit.

In the study published in the New England Journal of Medicine, 9000 General Electric employees across the US were recruited for the study, with half of them offered $750 to quit smoking, reports HealthDay News.

After a year, 14.7% of the smokers who were offered cash had stayed healthy, while only 5% of the control group who weren’t paid had managed to stay smoke-free.
