The Impact

BackgroundMarketing claims often have promoted specific perceptions that users should expect from acutely smoking that cigarette brand. Yet, little controlled study has determined the degree to which actual perceptions are based on the cigarette’s tobacco constituents in the absence of knowledge about the brand’s identity.Methods194 adult dependent smokers rated their perceptions on ‘liking’, ‘satisfying’, ‘strong’ and perceived amount of ‘nicotine’ after smoking ad lib one of their preferred brands of cigarettes. All did so either when blinded (n=118) or unblinded (n=76) to the brand they were given, with the blinding conditions from separate studies. These between-groups secondary analyses determined differences in perceptions based on blinding to brand, controlling for age and cigarettes/day.ResultsAll perceptions were lower for those smoking own brand under blinded versus unblinded conditions, as hypothesised. Consistent with lowered perceptions for smoking one’s own brand obtained from the 118 blinded to brand, their ‘somewhat’ ratings for a ‘how similar to own brand’ item indicated uncertainty, just mid-way between ‘not at all’ and ‘very much’ on the 0–100 visual analogue scale. (The 76 unblinded were already informed it was their own brand.)ConclusionsAcute perceptions of one’s own cigarette are substantially lower when smokers are simply unaware of brand, relative to those aware it is their preferred brand. Results support the notion that perceptions of smoking own brand are enhanced by marketing efforts to associate brands with expectations of pleasurable subjective effects, beyond the impact due solely to the cigarette’s manufactured product constituents.

AbstractBiomarkers of exposure to harmful tobacco constituents are key tools for identifying individuals at risk and developing interventions and tobacco control measures. However, tobacco biomarker studies are scarce in many parts of the world with high prevalence of tobacco use. Our goal was to establish a robust method for simultaneous analysis of urinary total 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL), N′-nitrosonornicotine (NNN), and cotinine at the Advanced Centre for Treatment, Research and Education in Cancer (ACTREC) in Mumbai, India. These biomarkers are validated measures of exposure to the carcinogenic tobacco nitrosamines 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) and NNN and the addictive alkaloid nicotine, respectively. The established method is characterized by excellent accuracy, linearity, and precision, and was successfully applied to the analysis of 15 smokeless tobacco (SLT) users and 15 non-users of tobacco recruited in Mumbai. This is the first report of establishment of such procedure in a laboratory in India, which offers the first in-country capacity for research on tobacco carcinogenesis in Indian SLT users.
