Participant milestones
Measure
Nicotine Lozenges
Nicotine lozenges, 2 or 4 mg, taken without restriction by mouth from 7 pm the evening before surgery until surgical admission the next day. Dosed according to time to first morning cigarette; if within 30 minutes of awakening, 4 mg lozenge used. If first cigarette smoked greater than 30 minutes of awakening, 2 mg lozenge used. Subjects also received an abstinence advisement: a brief (approximately 2 minute) behavioral intervention advising abstinence from smoking after 7 pm the night before surgery, the potential benefits of abstinence and to use a lozenge at usual smoking times.
Placebo Lozenge
Placebo lozenges, matching in appearance the 2 and 4 mg active nicotine lozenges, taken by mouth without restriction from 7 pm the night before surgery to the time of surgical admission the next day. Subjects also received an abstinence advisement: a brief (approximately 2 minute) behavioral intervention advising abstinence from smoking after 7 pm the night before surgery, the potential benefits of abstinence and to use a lozenge at usual smoking times.

OTHER_PRE_SPECIFIED outcome

Timeframe: Morning of surgery, pre-operatively

This item was measured using the Minnesota Nicotine Withdrawal Questionnaire, self-reported for the prior 24 hour period. This questionnaire consists of 15 items, each rated from 0 to 4, with a possible score of 0 to 60. A lower score indicates lesser withdrawal symptoms, and a higher score indicates greater withdrawal symptoms.
