Evidence from a recent systematic review found that people consistently consume more food and drink when offered larger-sized portions, packages or tableware than when offered smaller-sized versions. This suggests that policies and practices that successfully reduce the size, availability and appeal of larger-sized packages can contribute to meaningful reductions in the quantities of food and non-alcohol drinks people select and consume. The review was unable to highlight clear implications for tobacco control policy in relation to tobacco pack size due to gaps in the evidence base. This study will randomize smokers to smoke from smaller vs larger pack sizes and observe their cigarette consumption.
