“Diff” refers to difference scores (post-smoking minus pre-smoking score, negative scores indicate a reduction in symptoms post-smoking). At baseline, both groups smoked a usual brand cigarette.

ATSQ = American Thoracic Society Questionnaire; AV = aversion subscale; CES = Cigarette Evaluation Scale; CO = Expired breath carbon monoxide; CR = craving reduction subscale; Diff = difference score; ERTA = Enjoyment of Respiratory Tract Sensations; Ln TNEs = Total Nicotine Equivalents, natural log transofrmed; mFTQ = Modified Fagerström Tolerance Questionnaire; NWQ = Nicotine Withdrawal Questionnaire; PANAS Neg = Positive and Negative Affect Scale, Negative Affect subscale; PR = Psychological Reward Subscale; QSUF1/F2 = Questionnaire on Smoking Urges Factor 1/2; SS = Smoking Satisfaction subscale.
