It may be useful to compare the constituents of tobacco smoke as determined by Pontag with these results, both expressed in percentages.

Carbon monoxide	Morphine	Nicotine	Ammonia	Pyridine	Hydrocyanic acid

The following shows the nature of the dross opium extract used - expressed in percentages on the extract:

Water	Ash	Morphine	Insoluble in water
8.61	28.45	7.35	3.84

A smoker of this extract would use from five to six grams daily. She is considered to smoke in excess when she burns about double this quantity.

This dross opium extract is admitted by smokers to be stronger in effect than chandoo, so that to the pyridine bases, ammonia, hydrocyanic acid, and such-like substances this strength must be attributed, rather than to the morphine which has been shown to be present in very much less amount than in the smoke of chandoo.
