8.2.4 Gold et al. (A-5) investigated the effectiveness on smoking cessation of a nicotine patch, bupropion
SR, or both, when co-administered with cognitive-behavioral therapy. Consecutive consenting
patients 1n = 1642 assigned themselves to one of three treatments according to personal
preference: nicotine patch 1NTP, n = 132, bupropion SR 1B; n = 922, and bupropion SR plus
nicotine patch 1BNTP, n = 592. At their first smoking cessation class, patients estimated the number
of packs of cigarettes they currently smoked per day and the numbers of years they smoked.
The “pack years” is the average number of packs the subject smoked per day multiplied by the
number of years the subject had smoked. The results are shown in the following table.
