Current Every-Day Smokers (based on responses to the Tobacco - Smoking Status [Adult Protocol]) are asked the age when they initiated smoking every day. Current Some-Day Smokers and Former Smokers (based on responses to the Tobacco - Smoking Status [Adult Protocol]) are asked the second question about the age when they initiated smoking fairly regularly.
