OBJECTIVES: We compared biomarkers of exposure and potential harm in smokers of American Spirit (AS) to smokers of Marlboro, Newport, Camel, and Pall Mall. METHODS: We conducted secondary analysis on: (1) data from a randomized clinical trial (RCT); and (2) the Population Assessment of Tobacco Use and Health (PATH) Study. Biomarkers analyzed included: total nicotine equivalents (TNE); 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol and its glucuronides (total NNAL); N'-nitrosonornicotine and its N-glucuronide (total NNN);3-hydroxypropylmercapturic acid(3-HPMA); 2-hydroxypropylmercapturic acid (2-HPMA), 3-hydroxy-1 methylpropylmercapturic acid (HMPMA); S-phenylmercapturic acid(SPMA); 2-cyanoethylmercapturic acid (CEMA); phenanthrene tetraol(PheT);1-hydroxypyrene (1-HOP);8-iso-PGF2α; white blood count(WBC); prostaglandin E metabolite(PGEM); and high sensitivity C-reactive protein(hsCRP). RESULTS: AS smokers did not differ in TNE but had higher TNE per cigarette compared to other brands. Total NNAL, total NNN, CEMA, and 3-HPMA were lower in AS smokers. All other biomarkers were no different in AS smokers compared to all or the majority of the other brands. CONCLUSIONS: Levels of total NNAL, total NNN, acrylonitrile, and acrolein were reduced in AS smokers; however, it is not known whether reductions in exposure to these toxicants contribute to reduced harm. Higher TNE per cigarette smoked in AS smokers suggests a greater addictive potential compared to other brands. Regulatory action to ensure that consumers are not misled about the risks of the AS brand are recommended.
