The effect of chewing gum on tobacco withdrawal
(Disponible en anglais seulement.)
The authors assessed smoke craving and nicotine withdrawal in 20 smokers, half of whom were given free access to chewing gum during an enforced period of abstinence. They found that chewing gum does reduce craving and helps with withdrawal when a nicotine-dependent person cannot smoke.

Comment: Hopefully this coping technique for short-term abstinence can be translated into one for successful cessation.
