Multimodal assessment of the effect of chewing gum on nicotine withdrawal.

The present study was designed to evaluate the usefulness of chewing gum to reduce nicotine withdrawal, craving, and salivary cortisol concentrations during temporary nicotine deprivation. A total of 20 male smokers were studied under conditions when gum was and was not accessible during a 4-hour deprivation period. All subjects smoked an initial cigarette shortly after arrival for the two experimental sessions and were informed that they would be unable to smoke for the remainder of each session. The sessions consisted of each subject watching a movie, then waiting in the lab for two consecutive 30-min intervals. Self-reported nicotine withdrawal and craving were assessed four times and salivary cortisol five times during each experimental session. Results from this study indicate that chewing gum helps with self-reported withdrawal but not craving when a smoker is prevented from smoking. This study also provides preliminary data on the use of salivary cortisol as a physiological marker that may map these self-reports of nicotine withdrawal and craving.

The effect of chewing gum on tobacco withdrawal.

When smokers are in situations where smoking is prohibited, chewing gum is believed to reduce cravings to smoke. However, there is little scientific evidence to support this widely held assumption. The present study assessed craving for a cigarette and nicotine withdrawal in 20 dependent cigarette smokers under one of two conditions. All subjects smoked an initial cigarette upon arrival to the experimental session and were informed that they would not be allowed to smoke for the remainder of the session. The session consisted of each subject watching a movie, then waiting an additional 30 minutes. Half of the subjects were assigned to a Gum Condition where they were given free access to chewing gum throughout the experimental session; half were assigned to a No-Gum Control. Nicotine withdrawal was assessed immediately following the movie (Time 1) and again 30 minutes later (Time 2). Results from this study indicate that chewing gum reduces craving and helps with withdrawal when a nicotine-dependent person cannot smoke.
