Scientists have created temperature maps to explain how reduced ignition propensity (RIP) bands influence cigarette burn rate and possibly the chemical composition of the resulting smoke.RIP bands are designed to make a cigarette go out if it is not being actively smoked. Previous studies have shown a significant increase in levels of biomarkers for a few polycyclic aromatic hydrocarbons (PAHs) in smokers of RIP cigarettes, although the toxicological implications of these increases are currently unknown (June et al. Tobacco Induced Diseases 2011, 9:13).
