The expansion of world Ovide regulation aimed at reducing the ignition propensity of cigarettes is compelling major changes in cigarette designs that impacts deliveries, burn properties, construction, and consumer perception. The process started when Congress passed the Cigarette Safety Act of 1984, which established the Technical Study Group (TSG). The TSG's mandate was to evaluate the technical and economic feasibility of creating a cigarette with a reduced propensity to ignite upholstered furniture. The TSG issued a report in 1987 stating that it is technically and maybe commercially feasible to produce a cigarette with low ignition propensity and recommended the formation of a group to develop test methods. Congress passed the Fire Safe Cigarette ACT of 1990, which created the Technical Advisory Group (TAG) to develop a test method. The TAG issued a report in 1993 proposing two test methods. During the same time period many studies were performed and results published independently by the tobacco industry and CORESTA. ASTM published testmethod E2187 "Standard Test Method for Measuring the Ignition Strength of Cigarettes", which based on testing cigarettes on 15, 10, and 3 sheets of Whatman #2 filter paper. New York State was the first to implement low ignition propensity (LIP) cigarette regulation based on this test method in 2000. The regulation mandated that cigarettes sold in the state to have at least 75% Self Extinguishments on 10 sheets. This presentation will review the history and current status of LIP regulation, methods of complying, and new scientific findings.
