Feb. 11, 2009 -- No matter how much people are told about the hazards of
cigarette smoking, cold hard cash may be
the best motivator to get people to quit, a new study suggests.
University of Pennsylvania enrolled 878 employees of a multinational company
in a smoking-cessation program. They were assigned randomly to one of two
groups: 442 employees received information about the benefits of quitting, and
436 were told they would receive money in addition to participation in
Financial incentives were $100 for completing an educational session, $250
for quitting smoking within six months (as confirmed by a biochemical test),
and $400 for biochemically confirmed abstinence for an additional six
The researchers found that employees given financial incentives to quit were
much more likely to give up the habit than colleagues who only received
The nine- or 12-month quitting rate, as confirmed by testing, was 14.7% in
the incentive group, compared to only 5% in the group that only received
information, say the study researchers, led by Kevin G. Volpp, MD, of the
University of Pennsylvania School of Medicine.
"The [financial] incentive group had significantly higher rates of smoking cessation than did the
information-only group nine or 12 months after enrollment," the researchers
"Incentive-group participants also had significantly higher rates of
enrollment in a smoking cessation program, completion of a smoking cessation
program and smoking cessation within the first six months after
At a 15- or 18-month follow-up, 9.4% of the incentive group had remained
quitters, nearly three times the rate of the information-only group.
The researchers suggest that employers might do well to offer financial
incentives to get employees to quit because the financial benefit to employers
of workers quitting smoking is about $3,400 per year.

Volpp and one of his colleagues report receiving fees from health insurance
organizations, pharmaceutical firms, or both.
