Smokers believe “light” and “ultra light” cigarettes decrease health risks of smoking (Kozlowski, Goldberg, et al., 1998; Giovino et al., 1996). Smokers switch to low yield cigarettes instead of quitting (Giovino et al., 1996). Changes increased sales without harm reduction “The weight of the evidence indicates that lower-tar and nicotine yield cigarettes have not reduced the risk of disease proportional to their FTC yields” (IOM, 2001). Past modifications did not alter exposure: changing puff topography, covering vent holes New FDA regulation will eliminate use of “light” etc. Newer cigarettes: Eclipse, Advance, Omni Bold claims of reduced carcinogens Breland, Kleykamp, Eissenberg, 2006 Cigars 5.4% of US adults use (>1 in past 30 days) 3.9% of middle school students 10.8% of HS students Kreteks (clove cigarettes) and Bidis Pipes Waterpipe, or hookah CO exposure is much higher than cigarettes (Eissenberg et al., 2011) http://www.smokefree.gov/tob-cigarillo.aspx SOURCE: Adapted by CESAR from University of Michigan, “Smoking Stops Declining and Shows Signs of Increasing Among Younger Teens,” Press Release, 12/14/2010.

Effective media campaigns: ▪ ▪ ▪ ▪ Based on good market research Identify and tailor message to specific groups (market segmentation) Last longer and more intensive Use multiple media (TV, radio, newspapers) Primarily focus preventing illegal sales to minors Retailer education Active enforcement Systematic review by Stead, 2008 (Cochrane Collaboration) Active enforcement more effective in reducing sales to minors Little evidence of impact on perceived availability of tobacco products or on prevalence of youth smoking (only three controlled trials) Enacted in 1992 Required States to enact laws prohibiting the sale or distribution of tobacco products to those under 18 years old Required unannounced inspections of retail outlets and reporting of results “False buys” Established targets for “violation rates” Failure to meet targets could result in loss of funds—up to 40% of SAPT Block Grant Synar Violation Rates by Year Violation Rate 50% 40% 30% 20% 10% 0% 1997 1998 1999 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 Year Create a financial disincentive to use tobacco Based on known relationship between price and sales Elasticity of demand (Ed ) is percentage change in sales as a result of percentage change in price Ed = -1.5 (10% increase in prices results in 15% reduction in sales Relationship between price and sales (demand) complicated by role of addiction Adults Ed = -.40 (NCI, 1993) Less research on youth Illegal product for youth Generally believed that youth are more price sensitive Less disposable income Less addicted Youth Ed = -.9 to -1.5 “Policies that affect the price of tobacco products are the single most effective means of decreasing tobacco use, especially among youth and young adults.” (CDC, 1998) Tobacco companies often respond by decreasing wholesale price Excise Tax in Dollars State Tobacco Excise Taxes 5.00 4.50 4.00 3.50 3.00 2.50 2.00 1.50 1.00 0.50 0.00 4.35 3.46 1.41 NY RI TX State 0.30 0.17 VA MO Mission and Goals History and Organization Activities Opportunity for Student Participation The Virginia Youth Tobacco Projects (VYTP) Research Coalition was established to advance the prevention and treatment of youth tobacco use and nicotine dependence through a coordinated, multi-university program of basic and applied research. Build a statewide program of research on the causes and prevention of youth tobacco use Create active multi-university collaborations in carrying out the VYTP research program Attract new faculty scholars to work on problems of youth smoking Use VTSF funding as a base for attracting additional outside funding for youth tobacco research in Virginia Translate research findings into improved prevention services and policies The VYTP Research Coalition established in 2002 with funding from the Virginia Tobacco Settlement Foundation, now called the Virginia Foundation for Healthy Youth The VFHY supports three types of activities related to youth tobacco use: Media campaign Community-based prevention programs Research The VYTP Research Coalition includes over 40 faculty from seven of Virginia’s universities: The College of William and Mary George Mason University James Madison University University of Virginia Virginia Commonwealth University Virginia Tech Virginia State University VCU-IDAS serves as coordinating center Targeted grant funding to support research Small grant awards to fund preliminary/pilot studies and encourage participation by new investigators Research conference to disseminate findings to researchers, policy makers and practitioners Coalition meetings to facilitate networking and the development of new research collaborations Reports to facilitate research translation Statewide survey assessing: Frequency and quantity of use Perceived availability of tobacco products Exposure to environmental smoke Attitudes towards tobacco use Exposure to tobacco advertisements Conducted every other year beginning in 2001 Public school students in grades 6 through 12 Multi-stage sampling frame Access is being provided to students and postdocs for the first time Award ($500) for best student and best postdoc study Opportunity to present at VYTP conference in spring 2012 And, thank you for not smoking!
