Action of Tobacco Smoke 



349 



Exp. 7. Man aged 24, a smoker of seven years' standing. Smoked one 

 cigar, not inhaling. 



Exp. 8. Man aged 29, habitual smoker, frequent inhaler of cigarettes. 

 Smoked one Manilla cigar, inhaling all the time. (See fig. 5, e.) 



One last experiment in the series was made by smoking leaves which 

 are known not to contain nicotine. Dried lavender leaves were used for 

 this purpose, these being sold in certain parts of this country as " boys' 

 tobacco." The result of smoking such leaves is to cause a sensation of 

 stinging or scalding in the throat and mouth and some slight rise in blood- 

 pressure, the latter, however, not being comparable to that af tobacco. 

 Fig. 5, f, shows the effect of smoking such leaves. This chart was obtained 

 from the same subject as fig. 5, a and b.
