Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Background:

* Multiple social, psychological, and environmental factors contribute to adolescents' use of cigarettes. Environmental smoking cues have been shown to play an important role in the maintenance of nicotine addiction and in relapse to smoking. However, few studies have examined craving and cue-reactivity in adolescent smokers, even though craving appears to contribute to ongoing smoking and relapse in this age group.
* Another factor central to addiction is the rewarding effect of drugs, or the interaction between the person, the drug, and the environmental setting. However, more research is needed on whether environmental cues lead to increased smoking in adolescents.

Objectives:

\- To determine the effects of smoking versus neutral cues in adolescents who smoke on (1) craving, mood, and autonomic responsivity and (2) the relative reinforcing efficacy of tobacco cigarettes.

Eligibility:

\- Adolescents 12 to 17 years of age who are current smokers (at least five cigarettes per day for the past 6 months).

Design:

* This study will involve three study visits. Participants will be allowed to smoke before all study sessions and will give a breath carbon monoxide (CO) sample before all sessions. Participants must not use any illicit drugs or alcohol 24 hours before sessions.
* Visit 1 (baseline session): Participants will provide a urine sample and will be familiarized with the study room and session design.
* Visits 2 and 3: Participants will be connected to physiological recording devices to measure heart rate, perspiration, and other physical responses. After baseline readings, participants will be exposed to smoking cues at one experimental session and to neutral cues at the other experimental session.
* Before, during, and after cue presentation, participants will complete self-report measures of mood and craving and have physiological measures taken. They will then be re-exposed to smoking or neutral cues and engage in a self-administration procedure to examine the effect of cues on the reinforcing efficacy of cigarettes.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Objective:

To determine the effects of smoking versus neutral cues in adolescents who smoke on 1) craving, mood, and autonomic responsivity and 2) the relative reinforcing efficacy of tobacco cigarettes.

Study population:

25 adolescents who smoke at least 5 cigarettes per day.

Design:

Comparison-controlled, within-subjects design.

Outcome Measures:

During cue trials, primary measures include craving (TCQ-SF, VAS), mood (mood form, VAS), and autonomic (heart rate, blood pressure, skin conductance) responsivity. During self-administration trials, primary measures include breakpoint (final ratio completed), total number of responses, and number of cigarette puffs earned and taken. Secondary measures include baseline smoking history, mood, tobacco craving, smoking expectancies, nicotine dependence, and urinary cotinine and 3-hydroxycotinine.
