RT Journal Article SR Electronic T1 Divergence between strength indicators in packaging and cigarette engineering: a case study of Marlboro varieties in Australia and the USA JF Tobacco Control JO Tob Control FD BMJ Publishing Group Ltd SP 398 OP 402 DO 10.1136/tc.2009.033217 VO 19 IS 5 A1 Bill King A1 Ron Borland A1 Shadeed Abdul-Salaam A1 Gregory Polzin A1 David Ashley A1 Clifford Watson A1 Richard J O'Connor YR 2010 UL http://tobaccocontrol.bmj.com/content/19/5/398.abstract AB Objectives To investigate how the tobacco industry is adapting to regulatory action in accordance with provisions of the Framework Convention on Tobacco Control that targets misleading packaging and labelling. To relate the packaging and labelling of new cigarette varieties to their construction and performance.Methods The principal design features and tar, nicotine and carbon monoxide yields of the Marlboro ‘brand family’ in Australia were measured and compared with those of the US equivalents.Results Marlboro Red and Blue/Medium, could not be differentiated in preliminary tests in Australia, but were different in the USA. However, yield testing showed Marlboro Blue/Medium did not have lower tar and nicotine yields in either country, indeed being higher in Australia.Conclusions Colour can be used to market cigarettes as ‘milder’, independently of ISO yields and ‘Light’/’Mild’ descriptors. Banning of ‘Light’ and ‘Mild’ brand descriptors may be inadequate to end belief in less harmful cigarettes so long as the tobacco industry remains free to engineer ‘mildness’ and to use colours, other descriptors and design features to characterise varieties it wants to market as ‘milder’.
