Transdermal nicotine delivery systems are a cigarette smoking cessation aid designed to deliver nicotine into the systemic circulation via the skin. They have been found to reduce craving, thereby enhancing a patient's success for quitting smoking. However, side effects such as sleep disturbances and skin irritation, as well as incomplete smoking cessation are commonly experienced by users of such systems. Chrono Therapeutics, Inc. has developed an innovative programmable transdermal drug delivery system called the Chrono Quit Smoking Solution (CQSS2) that provides "off" periods (periods in which little to no nicotine is delivered), which is an advantage over existing systems that currently provide continuous delivery. The most important features of the CQSS2 are the periodic automatic dosing, plus the reduced side effects of sleep disturbances and potentially, skin irritation. The period when less nicotine is being delivered through the skin allows the skin an opportunity to "recover", thereby potentially reducing skin irritation. Another major benefit is the automatic dosing, which provides higher drug dosage at specific times of the day, leading to potentially greater success in quitting smoking. In this study, the CQSS2 will be used in conjunction with the Digital Coach application (app). The Digital Coach is a custom mobile app that provides behavioral support for the CQSS2. Together, the CQSS2 and the Digital Coach comprise the CQSS2 System.
