The ITC Policy Evaluation Project started its first project, the ITC Four-Country Project, to measure the psychosocial and behavioural factors of smoking in Australia, Canada, the United Kingdom, and the United States. The ITC team is currently collecting a seventh wave of data. The other ITC countries joined the project at different times after the Four-Country project began, and therefore are in different waves of data collection.
