Taxes, Cigarette Consumption, and Smoking Intensity: Reply This paper shows that smoking intensity, i.e. the amount of nicotine extracted per cigarette smoked, responds to changes in excise taxes and tobacco prices. We exploit data covering the period 1988 to 2006 across many US states. Moreover, we provide new evidence on the importance of cotinine measures in explaining long-run smoking behav...

This report describes patterns of cigarette smoking and interest in smoking cessation programs among employees in a public worksite (n = 6,000) and a private worksite (n = 14,000). Of the 622 employees who attended an employee assistance program (EAP) orientation, 110 (18%) were current smokers. A significantly greater proportion of public employees smoked cigarettes, smoked more heavily, and e...

Gastric emptying after a test meal was studied in 17 normal volunteers--10 habitual smokers and seven non-smokers. The solid component of the test meal was labelled with technetium and the liquid component with indium. After one meal the habitual smokers smoked two cigarettes. Emptying curves were produced for both technetium and indium, and the differences between curves for meals with and wit...

OBJECTIVES To describe smoking rates, age of initiation, and smoking cessation efforts among Aboriginal adolescent girls and boys in British Columbia, and examine the relationships between cigarette smoking and socio-demographic characteristics, depression and domains of life satisfaction. METHODS A secondary analysis was conducted of data collected from the British Columbia Youth Survey on S...

Studies of the effects of smoking on leukocyte telomere length (LTL) using cigarettes smoked per day or pack years smoked (PYS) present limitations. Reported high levels of smoking may not increase toxin exposure levels proportionally. Nicotine metabolism ratio (NMR) predicts total cigarette puff volume and overall exposure based on total N-nitrosamines, is highly reproducible and independent o...

BACKGROUND Spermatozoa are a group of cells that consume adenosine triphosphate (ATP) rapidly. Creatine kinase (CK), produced by creatine phosphate, is an energy reservoir for the rapid buffering and regeneration of ATP and can play an important role in sperm motility. Therefore, this study investigates the effects of cigarette smoking on human sperm CK activity in males who smoke. MATERIALS ...

BACKGROUND Approximately one-fourth of all cigarettes sold in the United States have the descriptor "menthol" on the cigarette pack. It is important to determine what socio-demographic factors are associated with smoking menthol cigarettes if indeed these types of cigarettes are related to smoking initiation, higher exposure to smoke constituents, nicotine dependence, or reduced smoking cessati...

1. The EEG and cardiovascular effects of smoking tobacco cigarettes of varying nicotine content were studied in Japanese chronic tobacco smokers. 2. Thirteen female and fifteen male adult normal volunteers were recruited for this study. 3. Each subject was asked to stop smoking the evening before coming to the laboratory the next morning, so they were approximately 10-12 hr deprived of cigarett...

OBJECTIVE Exposure to toxins in tobacco smoke is influenced by how a cigarette is smoked. Cigarettes have been designed to allow for a range of puffing behavior and to provide different, nonlinear tar and nicotine yields in response to different puffing profiles. However, puffing behavior and its influence upon risk-exposure has yet to be assessed outside the laboratory, in smokers' natural env...

We assessed the association between electronic cigarette (e-cigarette) use and peer cigarette smoking, a major risk factor for the initiation of cigarette smoking in adolescents. Data from the 2013 Korea Youth Risk Behavior Web-based Survey of 65,753 nonsmokers aged 13-18 years were analyzed using multiple logistic regression. A total of 3.8% of the Korean adolescents were 'ever e-cigarette' us...
