Effects of Smoking Cues on Tobacco Craving Responses and the Reinforcing Efficacy of Cigarettes in Adolescent Smokers

2014-07-24 14:00:55 | BioPortfolio

Summary

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.

Description

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.

Medical and Biotech [MESH] Definitions

Nicotine is highly toxic alkaloid. It is the prototypical agonist at nicotinic cholinergic receptors where it dramatically stimulates neurons and ultimately blocks synaptic transmission. Nicotine is also important medically because of its presence in tobacco smoke.

Strong dependence, both physiological and emotional, upon morphine.

Strong dependence, both physiological and emotional, upon heroin.

A synthetic opioid that is used as the hydrochloride. It is an opioid analgesic that is primarily a mu-opioid agonist. It has actions and uses similar to those of MORPHINE. It also has a depressant action on the cough center and may be given to control intractable cough associated with terminal lung cancer. Methadone is also used as part of the treatment of dependence on opioid drugs, although prolonged use of methadone itself may result in dependence. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1082-3)

A plant genus of the family SOLANACEAE. Members contain NICOTINE and other biologically active chemicals; its dried leaves are used for SMOKING.
