Trends in roll-your-own smoking: findings from the ITC Four-Country Survey (2002-2008).

Abstract

OBJECTIVE: To establish the trends in prevalence, and correlates, of roll-your-own (RYO) use in Canada, USA, UK and Australia, 2002-2008. METHODS: Participants were 19,456 cigarette smokers interviewed during the longitudinal International Tobacco Control (ITC) Four-Country Survey in Canada, USA, UK, and Australia. RESULTS: "Predominant" RYO use (i.e., >50% of cigarettes smoked) increased significantly in the UK and USA as a proportion of all cigarette use (both P < .001) and in all countries as a proportion of any RYO use (all P < .010). Younger, financially stressed smokers are disproportionately contributing to "some" use (i.e., ≤50% of cigarettes smoked). Relative cost was the major reas..
