To the Editor: George,1 who has received a research grant from Pfizer on smoking cessation, makes the manifestly incorrect statement that “there is no evidence for the effectiveness of cold turkey cessation, especially in moderate to heavy smokers”. In fact, it has always been the case that the most common method used by ex-smokers in their final successful attempt to quit is cold turkey.2
