Notes

ACE touchscreen question "How soon after waking do you smoke your first cigarette of the day?"

Field 3466 was collected from participants who indicated they currently smoke tobacco on most or all days, as defined by their answers to Field 1239 and currently smoke manufactured or hand-rolled cigarettes, as defined by their answers to Field 1239

Please note that the categories do not include a response for 15-30 minutes. This occurred due to an oversight during the design of the initial data collection process. However we have kept the response options the same during subsequent data collection exercises to maintain consistency for analytical purposes.
