Serum SCN levels for all PC smokers were higher than for non-smokers and lower than for current cigarette smokers. Levels were related to the amount of product smoke. Prior cigarette smokers had higher SCN levels when compared to PC users who had never smoked cigarettes, smoked a larger number of tobacco products per day, and reported inhaling into the chest more often. Prospective data on baseline cigarette smokers demonstrated that smokers who stopped all tobacco products had a greater drop in SCN and CO than those who switched to PC. The findings strongly suggest that cessation of all tobacco products is the best strategy for decreasing exposure to tobacco smoke. <\/jats:p>","DOI":"10.2105\/ajph.77.11.1412","type":"journal-article","created":{"date-parts":[[2008,11,29]],"date-time":"2008-11-29T13:03:17Z","timestamp":1227963797000},"page":"1412-1416","source":"Crossref","is-referenced-by-count":19,"title":["Does switching from cigarettes to pipes or cigars reduce tobacco smoke exposure?"],"prefix":"10.2105","volume":"77","author":[{"given":"J K","family":"Ockene","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T F","family":"Pechacek","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T","family":"Vogt","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K","family":"Svendsen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"844","reference":[{"key":"p_1","doi-asserted-by":"publisher","DOI":"10.1207\/s15324796abm0702_1"},{"key":"p_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(81)90187-2"},{"key":"p_3","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(73)91950-8"},{"key":"p_4","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(73)90668-5"},{"key":"p_5","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-82-4-537_1"},{"key":"p_6","doi-asserted-by":"publisher","DOI":"10.1378\/chest.72.1.33"},{"key":"p_7","doi-asserted-by":"publisher","DOI":"10.1016\/S0007-0971(81)80009-5"},{"key":"p_8","doi-asserted-by":"publisher","DOI":"10.1001\/jama.1985.03360230062023"},{"key":"p_9","doi-asserted-by":"publisher","DOI":"10.1001\/jama.1982.03330050059032"},{"key":"p_10","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.2.6099.1387"},{"key":"p_11","unstructured":"US Department of Health, Education, and Welfare, Public Health Service: Smoking and Health: A report of the Surgeon General.
