You will be asked to attend five lab sessions: one where you will use your own cigarette and four where you will sample an electronic cigarette. You will not be able to smoke any cigarettes or other combustible products (e.g. cigars, marijuana) prior to each visit. During the visits, you will complete questionnaires asking you about your mood and your response to the product. You will also have a breath test for carbon monoxide and vital signs will be taken. We will collect one urine sample from you.
Following lab sessions, you will take home all four JUUL pods and a device to sample as you wish for three days. At the end of the three days you will choose one pod to continue to use for another week. You will complete daily questionnaires about how much you use the electronic cigarette pods and your own cigarettes. You will not be charged for these pods.
