title: Transfer factor in smokers and non-smokers after smoking two cigarettes.
abstract: Impairments of lung functionality as long-term effects of cigarette smoking have been well established. To our knowledge, no study on acute recovery patterns in any important lung function index after smoking a very limited number of cigarettes has ever been reported. The present study reports recovery patterns of lung transfer factor (TF) and related parameters in smokers and non-smokers who smoked two Camel cigarettes. Lung transfer factor and other indices were determined by the single breath-holding technique. From our results, the TF and related indices of healthy Malaysians are similar to previously published normals of comparable age. On smoking two cigarettes, male smokers began to recover from the 30th minute; male non-smokers had not begun recovery even by the 50th minute. Extrapolation of the recovery curves suggests that a "safer" interval between cigarettes for male smokers is about 114 minutes.
