Penn Medicine Study Finds $600 Cash Incentive Doubles Smoking Cessation Rates

Nine out of every 100 heavy smokers successfully quit the habit when offered up to $600 in cash, compared to five out of 100 who received only standard medical support. The findings, published in JAMA this month, come from a trial conducted by researchers at Penn Medicine who sought to determine if immediate financial rewards could overcome the psychological and physical hurdles of nicotine addiction.

Lead researcher Joanna Hart, a pulmonologist at Penn Medicine, noted that many patients express regret about starting to smoke, yet the addictive nature of nicotine makes cessation difficult. The study specifically targeted individuals referred for lung cancer screening who faced barriers to high-quality healthcare, such as low incomes. These participants were typically long-term, heavy smokers, defined as those who smoked a pack a day for 20 years.

The trial compared two groups of patients. The first group received referrals to free telephone counseling quitlines and access to free nicotine replacement therapy, which are common approaches to quitting. The second group received the same standard interventions plus a cash incentive structure. Participants in the cash group earned rewards if they stopped smoking and did not relapse by the six-month mark, a milestone verified through urine or blood tests.

Hart explained that while the long-term health benefits of quitting are well documented, the immediate discomfort of withdrawal and the grief of giving up a long-held habit often deter patients. The financial incentive provided a tangible, immediate reward that helped smokers navigate the irritability and stress during the initial cessation period. The success of this method aligns with previous data supporting the use of financial incentives in healthcare.

Although paying for healthy behavior is not new, with other trials offering money for colonoscopies or annual checkups, some still question the logic of paying people to stop a bad habit. Hart countered that the $600 payment is minimal compared to the high healthcare costs associated with treating lung disease, heart disease, and stroke resulting from tobacco use. She added that once patients pass the withdrawal phase, which typically lasts six to 12 months, they are unlikely to return to smoking.

Looking ahead, researchers hope that health systems, insurers, and employers will adopt cash incentives for smoking cessation. Hart also suggested exploring payments for lung cancer screenings, noting that many patients do not complete these tests even when they are quick and painless. She referenced recent attention on Pope Leo’s lung cancer surgery as an example of how early detection makes the disease highly treatable, despite the condition’s scary reputation.

For smokers not receiving financial incentives, Hart recommended adding friction to the smoking habit. This includes creating rules to smoke only outside or removing cigarettes from the house to interrupt the automatic impulse to light up. She emphasized that quitting offers benefits at any age, stating that even a 70-year-old smoker stands to gain fewer health problems and a better quality of life by giving up cigarettes.
