The purpose of this research was to examine three important aspects of the smoking phenomenon that are, and will remain, important for the future of tobacco control research and policy. First and currently one of the most debated and researched topics in the tobacco research field relates to the group of products regarded by some as the potentially reduced exposure products (PREPs). We studied determinants of use of these products. Second aspect was to examine the socioeconomic subgroup of smokers based on their occupations who might potentially benefit from the use of PREPs and the third stage involved studying the smoking-behavior related subgroup of highly dependent hardcore smokers who might be the prime candidates for potential harm reduction through the use of PREPs.
