Randomisation
Subjects who completed the study screening assessments were assigned a unique randomisation identification number. Subsequently, each subject, based on the identification number, were assigned to use the study products according to one of four product sequences, which were prepared by Celerion, Inc. These sequences were ABCD, BDAC, CADB and DCBA where A is the Pulze HTS with iD Intense American Blend sticks, B is the Pulze HTS with iD Regular American Blend sticks, C is the Pulze HTS with iD Regular Menthol sticks, and D is subjects’ usual brand cigarettes.
