  19. Menthol Cigarettes • A report of the FDA’s Tobacco Products Scientific Advisory Committee (TPSAC)

  20. Menthol Cigarettes • Menthol is an organic compound (a naturally occurring monocyclic terpene alcohol), either derived from natural sources or synthesized, widely used in consumer and medicinal products • Pharmacologically, menthol in cigarette smoke has a cooling effect that may facilitate deeper inhalation and mask the irritation by nicotine and other smoke components • Menthol is present in most cigarettes in the United States, and in about 30% of cigarettes it is present in high enough concentration to make menthol the characterizing flavor

  21. Menthol Cigarettes • The FDA is charged with addressing the impact of the use of menthol in cigarettes on the public health • Its scientific committee developed a report on this topic, released in March 2011 • Menthol cigarettes are not common worldwide, but products are being developed

  22. Menthol: Possible Effects on Public Health Image source: Tobacco Products Scientific Advisory Committee (TPSAC), FDA. 2011

  23. TPSAC Conclusions: • Based on the conclusions to the nine questions, TPSAC provides the following general conclusions: Menthol cigarettes have an adverse impact on public health in the United States There are no public health benefits of menthol compared to non-menthol cigarettes

  24. TPSAC’s Recommendation to FDA Removal of menthol cigarettes from the marketplace would benefit public health in the United States
