Summary The changes in hand blood flow induced by sham smoking and tobacco smoking were studied in 15 normal subjects. The data were analysed by techniques that took full account of intra‐ and inter‐subject variance. A reduction of 16‐27% was observed during tobacco smoking, with little difference between an inhalation rate of one or three per minute. No significant fall in hand blood flow occurred during sham smoking. Similarly, a tachycardia was induced by tobacco smoking but not sham smoking. Our results indicate a specific effect of tobacco smoke even at the usual inhalation rate of one per minute.
