The hydrogen cyanide (HCN) content in mainstream smoke of 157 domestic and imported cigarette samples were determined with continuous flow method, and the results were statistically analyzed. The results showed that: 1) the HCN delivery of domestic cigarettes was obviously higher than that of imported ones; 2) the HCN deliveries of domestic Virginia and blended type cigarettes were significantly higher than that of imported blended type cigarettes; the HCN deliveries between domestic Virginia, blended and imported Virginia type cigarettes, as well as between imported Virginia and imported blended type cigarettes were not significantly different; 3) as for the domestic Virginia type cigarettes of different price categories, the HCN delivery of Category I was much lower than that of Categories IV and V; that of Category I, II and III as well as Category II, III and IV showed no significant difference; the HCN delivery of Category V was significantly higher than that of other categories.
