Health Canada Test Method T-115 - Determination of Tar, Water, Nicotine and Carbon Monoxide in Mainstream Smoke.Applicable to the collection and quantitation of the tar and nicotine content of sidestream tobacco smoke.Modifications for Intensive Smoking Conditions.I hope that the publication of this comprehensive information about the tar yields of brands of cigarettes will cause smokers to consider again the risk they are taking to their health by continuing smoking, but, if they are unwilling to stop the habit, to smoke a brand of cigarette with a tar yield significantly lower than the brand at present smoked. There has in recent years been some reduction in the average tar yield of cigarettes smoked because of the increase in the smoking of filter-tipped cigarettes instead of plain cigarettes and the change by some smokers to brands with a lower tar yield. Testing will continue, and I hope to be ready to publish a revised list about the end of the year, and biannually thereafter. This information about tar and nicotine yields of cigarettes is to be made available in poster and leaflet form and will be given wide publicity by the Health Education Council and others.

There are good grounds for believing that those smokers who choose to continue smoking are less likely to damage their health if they smoke cigarettes with a low tar yield. Cigarette smoke tar is known to contain substances which can causeĬancer and is thought also to be a major factor in causing bronchitis and emphysema. The level of tar yield is regarded as more important to health than the level of nicotine. Differences between brands of up to 2 mg of tar can generally be ignored. Where more than one brand have the same figure for tar yield, the brands with that figure are in alphabetical order. The figures which are set out below are rounded averages and the brands are listed in order of tar yield, those with the lowest tar yield being at the top. The packets of cigarettes from which the samples were obtained were purchased from retail outlets in various parts of the country during each of the six months July to December 1972. I have received from the Laboratory of the Government Chemist the tar and nicotine yields which were obtained from samples of 150 cigarettes of each of 101 brands.
