- Maximum Age: None
- Healthy Volunteers: f

Study Arms:
- Contingency Management (CM) (Type: EXPERIMENTAL): Condition provides contingent monetary reinforcement for smoking reductions (first 5 days) then for smoking abstinence (subsequent 14 days). Expired carbon monoxide (CO) levels will be the basis for determining reductions and abstinence.
- Noncontingent Reinforcement (NR) (Type: ACTIVE_COMPARATOR): Controls for effects of receiving payments, providing daily breath samples for CO level, and degree of interaction between patient and research staff. NR will allow them to earn an amount which is matched in amount to the expected average earned in CM contingent only on providing breath samples independent of the CO level attained.

Based on this trial design, predict the completion outcome and termination type (if applicable).
