Randomized Controlled Trial
Evaluation of biomarkers of exposure to selected cigarette smoke constituents in adult smokers switched to carbon-filtered cigarettes in short-term and long-term clinical studies.
Cigarette smoke is a complex aerosol that includes a gas vapor phase and a particulate phase. Inclusion of activated carbon in the cigarette filter can reduce some of the gas-phase smoke constituents implicated as toxicologically relevant. The present study evaluated exposure to selected gas-phase constituents when adult smokers switched to prototype cigarettes with a highly activated carbon filter. ⋯ The reductions continued consistently (p<.001) throughout the long-term studies. Switching to test cigarettes minimally affected the particulate-phase biomarkers. Statistically significant and consistent reductions in selected gas vapor phase biomarkers were observed when smokers switched to activated carbon filter cigarettes.

Randomized Controlled Trial
A smoking cessation intervention plus proactive quitline referral in the pediatric emergency department: a pilot study.
The prevalence of adult tobacco users who utilize the emergency department as patients or parents is disproportionately higher than the national average rates of tobacco use. Thus, it is advised that the emergency department be utilized as a venue for providing tobacco cessation counseling to adult tobacco users. Using a randomized control trial design, this pilot study evaluated the effect of a brief tobacco cessation intervention for tobacco using parents of children brought to a pediatric emergency department. ⋯ Quitline counselors were unable to reach 54% of participants. Our results reveal increased intentions to quit and trends toward quitting, however we experienced difficulties with participant retention. Suggestions for improvements in point prevalence and retention are given.

The National Institute of Mental Health (NIMH) convened a meeting in September 2005 to review tobacco use and dependence and smoking cessation among those with mental disorders, especially individuals with anxiety disorders, depression, or schizophrenia. Smoking rates are exceptionally high among these individuals and contribute to the high rates of medical morbidity and mortality in these individuals. Numerous biological, psychological, and social factors may explain these high smoking rates, including the lack of smoking cessation treatment in mental health settings. ⋯ A more complete understanding of nicotine and tobacco use in psychiatric patients also can lead to new psychiatric treatments and a better understanding of mental illness. Greater collaboration between mental health researchers and nicotine and tobacco researchers is needed to better understand and develop new treatments for cooccurring nicotine dependence and mental illness. Despite an accumulating literature for some specific psychiatric disorders and tobacco use and cessation, many unstudied research questions remain and are a focus and an emphasis of this review.

This study used over-the-counter (OTC) sales of nicotine replacement therapy (NRT) to investigate the impact of the introduction of smoke-free legislation in Scotland in March 2006 on smoking cessation behaviour. The time series of NRT sales (units and value) in Scotland from 2004 to 2006 were compared with the same period for the rest of the UK, and analysed using an ARIMA time series model. ⋯ There was no significant increase in NRT sales for the second half of 2006. These data suggest an increase in smoking cessation behaviour in the period immediately before the introduction of smoke-free legislation, but this was not sustained beyond the first few months of the post-legislation period.
