 The risks to participants are minimal. Participants will be healthy cigarette smokers who will abstain from smoking for varying periods of time and may have increased craving at the end of the experimental cue-exposure session. They will be given guided relaxation at the end of the session to reduce craving to pre-session levels and will be fully debriefed following the study. Some participants experience depression or other adverse symptoms during nicotine withdrawal. These will be fully described to the participants, and, if the symptoms become severe, the psychologistcounselor will counsel participants. The only other risks involve loss of confidentiality from information obtained during screening.
