Retrospective analysis of changing characteristics of treatment-seeking smokers: implications for further reducing smoking prevalence.

Objective: The goal of the current study was to empirically compare successive cohorts of treatment-seeking smokers who enrolled in randomised clinical trials in a region of the USA characterised by strong tobacco control policies and low smoking prevalence, over the past three decades.

Design: Retrospective treatment cohort comparison.

Setting: Data were collected from 9 randomised clinical trials conducted at Stanford University and the University of California, San Francisco, between 1990 and 2013.

A randomized clinical trial of the efficacy of extended smoking cessation treatment for adolescent smokers.

Introduction: Relatively few well-designed smoking cessation studies have been conducted with teen smokers. This study examined the efficacy of extended cognitive-behavioral treatment in promoting longer term smoking cessation among adolescents.

Methods: Open-label smoking cessation treatment consisted of 10 weeks of school-based, cognitive-behavioral group counseling along with 9 weeks of nicotine replacement (nicotine patch).

Assessing teen smoking patterns: the weekend phenomenon.

Background: Adolescent cigarette smokers may have more daily variability in their smoking patterns than adults. A better understanding of teen smoking patterns can inform the development of more effective adolescent smoking cessation interventions.

Methods: Teen smokers seeking cessation treatment (N=366) reported the number of cigarettes smoked on each day of a typical week.

Failure to improve cigarette smoking abstinence with transdermal selegiline + cognitive behavior therapy.

Aims: To examine the effectiveness of transdermal selegiline for producing cigarette smoking abstinence.

Design: Adult smokers were randomly assigned to receive selegiline transdermal system (STS) or placebo given for 8 weeks. All participants received cognitive behavior therapy (CBT).

Withdrawal symptoms over time among adolescents in a smoking cessation intervention: do symptoms vary by level of nicotine dependence?

Nicotine dependence may be expressed differently in teens than in adults. Thus, it may not be sufficient to build diagnostic and cessation treatment strategies for teens based on adult-derived clinical and research data. This is the first study to prospectively examine the development of withdrawal symptoms by level of nicotine dependence among adolescent smokers.
