Two types of tests will be conducted with each participant, regardless of self-reported quit status. NicAlert strip tests (semi quantitative test) will be used to test saliva cotinine during weeks 2, 3, 5, 6, 8, 9, 11, and 12 of the participant's participation. This test will provide us with an accurate indicator of whether or not women have quit smoking while reducing the cost of the pilot study. A quantitative liquid chromatography cotinine test conducted by ARUP Labs will be used to test urine during weeks 1, 4, 7, and 10 for all women regardless of self-reported and smartwatch smoking status. This test, while more expensive, will provide us with the concentration of cotinine for each participant. This number can be directly compared to the self-reported and smartwatch reported number of cigarettes smoked as a way to validate self-report and smartwatch accuracy even when a participant has not quit smoking completely.
