Objectives (1) Compare social norms and perceived peer use between college student cigarette, e-cigarette and/or hookah users and nonusers; and (2) Determine variables associated with social influences. Participants Undergraduate students attending a large university in the Southeast U.S. (N=511). Methods An April 2013 online survey assessed use of three types of tobacco, social norms, perception of peer use, number of smokers in life, exposure to secondhand smoke, and demographic characteristics. Results Participants indicated greater acceptance of emerging tobacco products than for cigarettes and consistently overestimated the percent of peers who use various tobacco products. Males and current users had higher social norm scores for all three forms of tobacco. Conclusion To counter marketing of alternative tobacco products, education about the dangers of their use needs to be implemented across college campuses as part of a comprehensive tobacco control strategy that also includes tobacco-free campus policies.

Several authors have demonstrated that coumarin (1,2-benzopyrone) in combination with cimetidine can produce objective antitumor responses in some patients with advanced renal cell carcinoma. The purpose of this report is to review the clinical development of coumarin, with or without cimetidine, with special reference to renal cell carcinoma (RCC). Previously unpublished data concerning the survival of a population of patients with RCC, who were treated on a phase I trial of coumarin and cimetidine, are presented. The rationale and study design of an active randomized, double-blinded, placebo-controlled trial of coumarin for RCC are discussed. A progress report is given for an ongoing phase I trial of oral 7-hydroxycoumarin, the major human metabolite of coumarin.

Public support for Lexington-Fayette County, Kentucky's smoke-free law, perception of health risks from exposure to secondhand smoke (SHS), smoking behaviors, and frequency of visiting restaurants, bars, and entertainment venues were assessed pre- and post-law. Two cohorts of noninstitutionalized adults (N = 2,146) were randomly selected and invited to participate in a 10- to 15-min telephone survey. Public support for the smoke-free law increased from 56% to 63%, and respondents were 1.3 times more likely to perceive SHS exposure as a health risk after the law took effect. Although adult smoking and home smoking policy did not change post-law, adults frequented public venues at least as much as before the law. Lexington adults favored the smoke-free legislation despite living in a traditionally protobacco climate. The smoke-free law acted as a public health intervention as it increased perception of risk of heart disease and cancer from SHS exposure.

Polytobacco users were more likely than single users to consume emerging tobacco products, (ie, hookah and electronic cigarettes). Males, underclassmen, and racial/ethnic minorities were more at risk for polytobacco use. As young people are particularly prone to nicotine addiction, there is a need to further investigate polytobacco use among college students.
