“ charge of mucus from the nose; and there have been several in- 
“stances of headachs, toothachs, and ophthalmias relieved by this 
“means: and this is to be particularly remarked, that when this 
“ discharge of mucus is considerable, the ceasing or suppression of 
“it by abstaining from snuff, is ready to occasion the very disorders. 
“ of headach, teeth, and pine nce- a which it had formerly re- 
“ lieved. 
“« Another effect of snuffing to be taken notice of is, that as a part 
“ of the snuff is often carried back into the fauces, so a part of this 
* is often carried down into the stomach, and then more certainly 
“ produces the dyspeptic symptoms mentioned. These are the con- 
“ siderations that relate to snuffing; and some of them will readily 
“ apply to the other modes of using this drug. 
«« Smoking, when first practised, shows very strongly the narcotic, 
% vomiting, and even purging-powersof tebaceo, and it is very 
« often useful as an anodyne; but by repetition these effects dis- 
“appear, or only show themselves when the quantity smoked is 
« beyond what habit had before admitted of; and even in persons 
“ much accustomed to-it, it may be carried so far as to prove a 
“ mortal poison. From much smoking all the same effects may 
* arise which we said might arise from the excess in snuffing. 
«‘ With respect to the evacuation ef mucus which is produced by 
« snuffing, there are analogous effects produced by smoking, which 
« commonly stimulates the mucous follicles of the mouth and fauces, 
“and particularly the excretories of the salivary glands. By the 
“evyacuatien from both sources, with the concurrence of the nar- 
“ cotic power, the toothach is often greatly relieved by it; but we 
‘¢ have not found the smoking relieve headachs and ophthalmias so 
«« much as snuffing often does. Sometimes smoking dries the mouth 
‘and fauces, and occasions a demand for drink; but, as commonly 
‘« the stimulus it applies to the mucous follicles and salivary glands 
«« draws forth their liquids, it occasions on the other hand a frequent 
_ spitting.
