Summary

The most widely-accepted animal model of nicotine withdrawal states stopping nicotine makes rewarding events become less rewarding. The current study will test if this is true in humans. If we find tobacco abstinence does make rewards less rewarding, this would suggest new symptoms to add to official descriptions of nicotine withdrawal. It would also suggest we need to develop new behavioral and pharmacological interventions to correct this problem. If stopping smoking does not make rewards less rewarding, this would suggest this animal model does not apply to the human condition and we need to continue to search for an animal model of tobacco withdrawal that is relevant to smokers stopping smoking.
