Researchers and healthcare providers are constantly looking for innovative and effective ways to help people quit smoking. One of those ideas, paying smokers to quit, seems to be successful, according to a large review study. Financial incentives varied from cash, to vouchers for goods, to self-deposits, meaning the participants paid themselves to quit, and the dollar amount ranged from $45 to $700. No matter the amount, those who received rewards were significantly more likely to have stopped smoking than those who received no payment. Those people were also less likely to start smoking again after the incentive program was complete.
