'A pack a day for 20 years': Smoking and cigarette pack sizes

The extensive literature on smoking behaviour has focused on numerous aspects such as the factors that influence the decision to start smoking and, for smokers, what factors influence consumption and decisions to quit. This study focuses on the determinants of the typical daily volume of cigarette consumption. In particular the impact of cigarette pack sizes on the typical daily consumption of smokers is investigated. Results are presented from a statistical model which allows for `pack-effects¿ in daily consumption levels.
