Summary

This study compares how people use two generations of IQOS heated tobacco devices—the newer IQOS Iluma i and the older IQOS 2.4—and how each affects their smoking behavior and sensory experience. Participants attend two lab visits, use both devices, and have their puffing patterns recorded. The goal is to see if device design or tobacco stick flavor influences puffing, throat hit, and satisfaction.
